Node.js web development agency in Athens.

Node.js put JavaScript on the server and removed the oldest tax in web development: two languages, two teams, and a translation layer between them where the bugs live. With Node.js web development, validation rules, pricing logic and types are written once and used on both sides.

It is also built for the work a modern product actually does — thousands of connections waiting on a database, a payment provider or an ERP at the same time. Node handles that concurrency on a single thread, without the memory cost of a thread per request, which is why Netflix, PayPal, LinkedIn, Uber and eBay run on it.

And it has the largest ecosystem in software. Whatever you need to integrate — a payment provider, an ERP, a courier — a maintained, tested client usually exists already, so the budget goes on your product rather than on plumbing.

APIs

REST and typed APIs designed as the product's interface, not the website's — so the web platform and the iOS and Android apps are two clients of one system that already works.

Integrations

Two-way, real-time connections to ERP, warehouse, accounting, courier and payment systems, with retries and reconciliation for the day one of them is down.

Real-time platforms

Availability, pricing and booking that change by the second, notifications, live dashboards and the queues behind them.

Payments and accounts

Checkout, refunds, invoicing and user accounts, where a transaction either completes or does not — there is no state where money was taken and an order was not written.

Admin and back office

The tools your own team uses every day — orders, content, customers, reports — built on the same API rather than beside it.

TypeScript throughout, so the shape of every request and response is checked before it ships. PostgreSQL underneath, because a system that holds orders, customers and money needs a database that refuses impossible data rather than trusting every line of code that touches it.

On the front, React.js web development in Next.js shares those same types with the server, so the website cannot disagree with the API. On the phone, React Native mobile app development does the same — one set of rules, three places it is enforced.

Most outages in a web product start somewhere else: a payment provider times out, an ERP goes down for maintenance, a courier's API changes a field. Node.js web development done properly assumes that — every external call has a timeout, a retry and a record, and nothing is lost when a partner is slow.

Deployed with monitoring, backups and zero-downtime releases from the first version, so shipping is routine rather than an event, and the first person to know about a problem is us rather than your customer.

Briefing

You tell us what you are building, what exists already and what is in the way. We reply within two working days — with questions, or with the honest answer that you do not need us.

Blueprint

Scope, architecture, the stack and a fixed plan, agreed before a line of code is written. You know what is being built, in what order and why.

Build

The API, the database and the integrations built in Node.js, TypeScript and PostgreSQL, tested against the real systems they connect to. Working software every week or two, on a staging address you can open, rather than a reveal at the end.

Launch and after

Release, monitoring and a named team that stays. The code, the design files and the data are yours.

19 years of work for brands including COSMOTE, Piraeus, Avène, MARKET IN, SCORPIOS, TRVL AIR and NEXTCOMMERCE — national-scale platforms and e-commerce systems integrated with the software that runs the business behind them.

The back end is never a separate supplier's problem: the same team builds the interface on top of it, so a change to one is planned with the other.
