EyeBuy

Custom app development
Livestream shopping
MVP
EyeBuy is a livestreaming shopping app, allowing you to watch a live stream and instantly order things that you like. It was a new project in our portfolio — we hadn’t made such apps before, but we accepted the challenge.
Our e-commerce developers built an app, and in our first streams we used the Socket.io library and added every real-time user into a variable.
Test streams attracted big brands such as Letoile, Mascott, and Decathlon. On the Mascotte stream, the number of unique viewers reached 500 (as opposed to 40 on the prototype stage).
Users added items to the cart right on the stream and were redirected to an already compiled cart on the shop’s website.
We used React and React Native for the frontend app development for web and mobile respectively, and Node.js for the backend part.

EnerGO

IoT
UX/UI design
Custom app development
EnerGO is a power bank renting app that works in the Moscow metro and cafés. Users can take one power bank from one station and return it at another. The client got this idea after his trip to China, where he met manufacturers of big and small power banks.
Initially, we planned to make just one app, for power bank users, but two additional apps came along the way: an app for advertisers and an app for maintenance.
The main app consists of two blocks: the user app and the module for working with the station. We had to decipher original Chinese documentation from a reference project to make sure everything works as planned.
We contacted the station manufacturers from China and reverse-engineered the old code written in Java — that’s where Node.js came in handy.
We designed and developed all three apps.
As of 2021, there were 730 stations in Moscow, 100 of them in the metro. EnerGO estimated its active users number at 2 million.

Accelerist

Website development
Fundraising
UX/UI design
Accelerist is an online fundraising platform that helps non-profit organizations raise money from commercial organizations. NPOs can find sponsors through filtered search, email them, and communicate directly. Basically, our task was to create a Tinder for NPOs.
We built the code, created UX/UI design, and enhanced user flow. One of the biggest changes we made — we removed the need for sponsors to register.
Their data is taken from the databases and presented as cards on Accelerist, and any NPO can e-mail them a potential pitch. For that, we integrated ZoomInfo.
We used Node.js for the backend and React for the frontend.
The development took 5 months and cost the client $49,400.

Fitness App

Custom app development
UX/UI design
FitTech
FitnessApp is an app that connects coaches to their clients. Potential athletes can find new coaches or get in touch with the trainers they used to work with in the gym. We developed the app from scratch and created the design.
For coaches, we implemented access to clients’ info and training schedules, as well as an ability to create fitness programs.
For clients, we provided access to their personal programs, notifications about messages and training, and a training calendar; we also added a chat for both parties.
The app was built on React Native, the web — on React, and the backend was written on Node.js using the nest.js framework.
The project took us 3 months.

Node js development services process

1

Discovery & planning

Result: A clear product vision, technical roadmap, and prioritized feature list.
Time period: 1-4 weeks
Our product discovery process, although an added service, is almost necessary in today's world. In that phase, we dig into your business needs, audience, and product vision to define a solid foundation for development. Discovery is perhaps one of the most important stages of Node.js development, as it can save you thousands of dollars. Quantitative and qualitative analysis, as well as calculating unit economy, can find that some features aren’t necessary or worth investing into.
You’ll get a detailed project plan and timeline. And, more importantly, you won’t be paying for the features your users don’t actually need.
2

UX/UI design

Result: Intuitive, conversion-focused interface ready for development.
Time period: 6-12 weeks
Our designers turn your concept into an experience users will love. We craft user flows that reflect real customer behavior and design visuals that make every interaction intuitive. You’ll see interactive prototypes before development starts — so you can test, refine, and feel confident in the direction. The outcome is a product that not only looks great, but solves real business problems through usability and engagement.
3

Development & integration

Result: Fully functional, scalable app built on a reliable Node.js backend.
Time period: 8-16 weeks
Once the design is approved, our developers get to work. Using Node.js and complementary tools like Express.js or NestJS, we build a clean, modular backend that’s easy to maintain and scale.
We handle API development, databases, and integrate third-party services seamlessly to ensure your app works fast and securely. Throughout the process, you’ll get regular updates, demos, and access to our project management tools to stay in control of the development process.
4

Testing & quality assurance

Result: A stable, bug-free product ready for launch.
Time period: in parallel
We test every feature across devices and environments throughout the entire development process. Automated and manual QA checks help us detect and fix issues early, ensuring everything works exactly as intended. However, this stage is where we run the final tests, with the goal to ensure smooth performance, top security, and zero critical bugs. We test every component of your app — functionality, security, performance, and compatibility.
5

Launch & ongoing support

Result: A live product supported and optimized for growth.
Time period: ongoing
After the launch, we keep your product in top shape. Our support team monitors performance, applies updates, and implements new features as your business evolves. If you need optimizing load speed, adding integrations, or scaling for more users, we make sure your product continues to deliver value. With Purrweb, you get a long-term tech partner who helps your product grow sustainably instead of a one-time vendor.

Why develop with Node.js

High performance for demanding apps

Node.js is built for speed. Its event-driven, non-blocking architecture allows apps to process thousands of simultaneous requests without slowing down. It’s perfect for fast-paced environments like marketplaces, dashboards, or SaaS products.
For example, global platforms like Netflix and LinkedIn use Node.js to serve millions of users while keeping response times fast. As a result, users enjoy a seamless experience, and your business scales without performance issues.

Scalability from day one

When you build with Node.js, you’re setting your product up for long-term growth. It supports both vertical and horizontal scaling — meaning you can easily add features, microservices, or servers as your audience expands. Whether you’re running a startup MVP or preparing for enterprise-level traffic, Node.js keeps performance steady while giving you flexibility to adapt fast to new demands or business goals.

Faster time to market

Node.js uses JavaScript on both the frontend and backend, allowing teams to work faster and more efficiently. Less context switching means fewer delays, faster communication, and shorter delivery cycles. For instance, building an MVP with Node.js can help you validate your idea and attract investors in weeks instead of months. You get your product to market faster — and start getting results sooner.

Rich ecosystem and community

Node.js comes with an enormous open-source ecosystem — over a million ready-to-use libraries via npm (Node Package Manager). That means developers can integrate pre-built solutions instead of reinventing the wheel, cutting down development time and costs.
With a large, active community behind it, Node.js is constantly evolving and supported by best-in-class tools. You’re never stuck waiting for outdated technologies to catch up.

Cost efficiency through full-stack JavaScript

Using Node.js allows your team to build both frontend and backend in a single programming language — JavaScript. That reduces the need for separate specialists, simplifies communication, and speeds up development cycles. But for businesses, this means fewer hours spent, smaller teams required, and lower long-term maintenance costs. You get more value from every dollar invested while keeping quality and speed high.

5 great tools for Node.js development

Express.js

Express.js helps us build stable and scalable web apps quickly. It provides the structure for routes, data flow, and server logic so your app runs smoothly from day one. Express.js is the go-to framework for Node.js because it’s lightweight, fast, and flexible. It gives developers the essential structure for building web apps and APIs without unnecessary complexity.

NestJS

NestJS builds on top of Node.js and Express, adding a powerful layer of organization and scalability. It’s the perfect choice for complex or enterprise-level applications that need long-term stability. NestJS can also help you minimize long-term tech debt and maximize ROI.

Socket.io

If you need live chats or instant notifications, Socket.io is a go-to. It enables real-time features that keep users engaged and ensures data updates instantly — no page refreshes needed. Imagine a logistics dashboard that updates shipment statuses live or a trading platform showing second-by-second market data — that’s what it does best.

TypeScript

In our nodejs development services, we use TypeScript to minimize bugs and improve code quality. It adds static typing to JavaScript, which means potential errors are caught before the app is even run. This drastically reduces runtime bugs — one of the biggest pain points in large Node.js projects. And since both frontend (React, Vue, etc.) and backend (Node.js) can share TypeScript types, your full-stack development becomes more cohesive. 

MongoDB & PostgreSQL

Whether your project needs flexibility or strict data consistency, we pick the right database technology. Node.js works great with both MongoDB and PostgreSQL to ensure speed and stability.

Why Purrweb’s perfect for Node.js

Over 500 finished projects

We have completed more than 500 projects in different niches — MedTech, EdTech, IoT, E-commerce, you name it. Even if your niche is something completely outstanding and innovative, we’re ready to gather the necessary experience as fast as possible.
For example, when crypto was only getting started, and we didn’t have as much experience in it as we do now, we enthusiastically learned everything we could to develop a crypto wallet named Broex.

Real value even before the deal

We will deliver valuable insights even before the deal is made. Our manager will delve into your project’s details and estimate it right after you submit a form. After you get an estimated budget of your Node.js development services and a quick demo of our project discovery phase, we will proceed to signing a contract — and an NDA, if you need it.

Easy collaboration with clear handoffs

We, as a node js development company, design and develop in a way that makes things convenient for everyone — not just for your end users, but also for your in-house team, should you want to continue on your own or scale your project in the future. We will ensure our documentation is full and understandable. No handoff hustle with us!

Basic and complex projects

We’re equally excited about the simplest apps and the most sophisticated things! We will find a way to elevate a basic project to the next level, and also how to handle a complex endeavor with ease and top-notch quality. At Purrweb, we love any kind of a challenge!

What our clients say

William Angel
Personalised — wellness app design

Purrweb is one of the fastest agencies if not the fastest one that I’ve ever worked with. In terms of budget, the cost was very affordable — not too much more than you expect from a typical freelancer yet the quality level that you’re buying for that is definitely top end. I'd love to mention that we originally planned to build MVP design but the design that we got is much better — the guys from Purrweb weren’t just a yes-man, they were challenging some of our ideas with constructive feedback and the product we ended up with as a result is very high quality.

Personalised — wellness app design
Healthcare, Marketplace, Personalized, Push-notifications, Dsdashboards

KEM — Payment app

My name is Seth Abel and I’m CEO at Fintech company called KEM. We provide payment services and help people to connect with each other in terms of the financial matters. We really needed help with developing an MVP. Our banking partners required an MVP from us to demonstrate our ability to put up a product. I think the job was done really swiftly and very effectively. A good product was delivered, so I was really happy with the services and I would definitely recommend Purrweb.

Founder
Buzz

My name is Matt Brzowski, and I'm the founder of a local events app called Buzz. I came to Purrweb with an app idea, and the team helped us come up with a company brand. We went through the whole design process and made an MVP that we could take into development. The design team at Purrweb is extremely qualified and open to iterating on designs. We were at an early stage with our company when we came to Purrweb, and the team was able to stick with us through all the big transformational work. They helped us cater our logo, brand, and our mobile app to accomplish our goals. I really liked the design prowess and the flexibility.
