Chosen per project — never by hype

The Stack Behind Everything We Ship

We are technology-agnostic on purpose: the product decides the stack, not our comfort zone. Here is what we reach for — and how deep the expertise goes in each area.

Team Skills

The Experts You Get On Your Project

Hire a single specialist or a full pod — every role below is available for services, products and customization work.

App Developers

Flutter-first engineers who ship both stores from one codebase without the cross-platform jank.

Both stores, one codebase
Game Developers

Casual-game specialists — procedural levels, juicy feedback, tiny installs, full monetization.

Retention-first design
Web Developers

From high-converting landing pages to full SaaS products with payments and dashboards.

Fast & SEO-ready
Backend Engineers

APIs, admin panels and automations that stay boring — in the best possible way.

Boring on purpose
UI/UX Designers

Design systems, app screens and store assets that convert browsers into installs.

Screens → store assets
QA & Release Engineers

Testing, store submission, policy forms and rejection fixes — the last mile, handled.

How the Stack Ships

Every Delivery Runs the Same Pipeline

Tools are the easy part — this is the pipeline every project travels, and the checks that pass before code reaches you.

Version control & review

Everything lives in Git with meaningful history. Non-trivial changes get a second pair of eyes before merging.

every PR
CI on every push

Builds, linters and tests run automatically — broken code is caught in minutes, not discovered by users.

1m 47s
Testing where it pays

Unit tests on logic that earns money or breaks silently: payments, limits, parsers, state machines.

3m 12s
Docs & clean handover

Setup guides, architecture notes and deployment steps ship with the code — your next developer starts in hours.

Security basics, always

Prepared statements, server-side verification, secrets out of source, least-privilege keys. Boring and non-negotiable.

Monitoring from day one

Crashlytics/ANR tracking on apps, error logging on web — we know about problems before your reviews do.

Our Rule

How We Choose a Stack for You

It's simple enough to write as code — because that's how we actually run it.

zynvonex — stack-picker.js
function chooseStack(yourProject) { // 1 · product first — never tech first const needs = listen(yourProject.realUsers); // 2 · your hosting & budget reality let stack = fitsWithin(needs, your.hosting, your.budget); // 3 · maintainability beats trendy stack = prefer('boring', 'documented', 'easy to hire for'); // 4 · proof, not preference return weShippedWithIt(stack) ? stack : keepLooking(); }
  • Product first

    Offline support, realtime sync, tiny installs, SEO — what the product needs narrows the field fast.

  • Your hosting reality

    Built for where you can actually run it — shared PHP hosting to serverless — so bills stay predictable.

  • Maintainability beats trendy

    Boring, documented technology wins. Your next developer must be easy to hire.

  • Proof, not preference

    If we propose it, we've shipped with it — with examples from our own products.
