Why JavaScript —
and why it's not going anywhere

JavaScript is the only language that runs natively in every browser on the planet. Add Node.js, and the same language powers your backend too — which changes how teams are built and how fast products ship.

One language, full stack

One language, full stack

Frontend and backend in JS means shared context, shared tooling, and engineers who can move across layers without friction.

The largest ecosystem on the planet

The largest ecosystem on the planet

npm has more packages than any other registry. Whatever you need to build, someone's already solved half of it.

Built for the modern web

Built for the modern web

Real-time features, async by default, event-driven architecture — JS was designed for how the web actually works today.

Zero friction to scale

Zero friction to scale

From startup MVP to enterprise platform — the stack grows with you. Node.js handles serious concurrency without breaking a sweat.

AngularJS → Angular migration
jQuery refactoring
Monolith decomposition

JS-powered storefronts and headless builds — for when the platform needs to get out of the way.

What we actually
build with JavaScript

icon

Web Applications

Custom SPAs, portals, and dashboards — built for the people who use them, not just to check a box.

icon

Real-Time Features

Live updates, notifications, collaborative tools — for apps where latency actually matters.

icon

APIs & Backend Services

Node.js APIs that connect your frontend, mobile, and third-party services without becoming a maintenance nightmare.

icon

Headless Storefronts

Fast, flexible eCommerce frontends decoupled from the backend — Shopify Hydrogen, headless CMS, custom builds.

icon

Internal Tools & Dashboards

The unglamorous stuff that keeps businesses running.

icon

Legacy JS Migrations

AngularJS, jQuery, JS monoliths — we've done the messy migrations so you don't have to figure it out alone.

Why Vilmate

Your Team, Not a Rotation
Speed Without Shortcuts
ISO-Certified Quality
Nearshore Advantage
image
You work with the same developers start to finish. No handoffs, no "let me check with the team", no lost context mid-project.
image
We move fast — but not at the expense of code quality or architecture. Fast and clean aren't mutually exclusive.
image
Our processes are ISO-certified. That means structured code reviews, clear documentation, and predictable delivery.
image
Based in Eastern Europe, we overlap with US and EU working hours. Real-time collaboration without the timezone headache.

Questions we hear
before projects start

Do you work with TypeScript?
Yes — TypeScript is our default on most new projects. We can also work with existing JS codebases and migrate them incrementally if needed.
Can you take over an existing JavaScript project?
That's one of our most common starting points. We do a code audit first, then onboard without disrupting your current release cycle.
Do you build both frontend and backend, or just one?
Both. Our fullstack JS teams cover the entire product — from the UI to the API layer and database integrations.
Which frameworks do you use?
Mostly React, Angular, Node.js, and NestJS. We recommend based on your project constraints, not our comfort zone.
How do you handle knowledge transfer if we bring development in-house later?
We document as we go — architecture decisions, component logic, API contracts. Handoff is part of the process, not an afterthought.

    E-commerce Personalized Search Examples Make Personalization Easier to Judge #AI & ML
    Personalized search is easy to like in theory. Better results, smarter product discovery, more relevant buying journeys—all sound great. Also slightly abstract, until you see what can happen when a real shopper types a real query, and the store uses the context already sitting in front of it. Theory still matters. That is why we […]

    E-commerce Personalized Search Makes Every Query Work Closer to Purchase #AI & ML
    A shopper lands on an e-commerce site with a clear idea in mind, clicks the search icon, that tiny symbol of promised convenience, and types something simple: “black dining table.” There is a small hope behind that query. Maybe the store will understand the style, price range, previous browsing, and the fact that they have […]
