The reverseBits stack
Pick the stack that fits your roadmap, not the other way around.
Thirteen production-grade technologies, each owned by senior specialists who ship them every day. Browse what we build with — and on each tech page, see the team, projects, and qualify-fit criteria that decide whether we're right for you.

Long-running Node services with backpressure, structured logging, and observability you can debug at 2am.
Express.js
16 specialists
The minimal API surface that just works
When the team just needs a thin REST layer over Postgres — typed routes, JWT, validation, no ceremony.
NestJS
12 specialists
Modular monoliths the team won't outgrow

Flask
9 specialists
Right-sized Python services without the framework tax
When Django is too much; SQLAlchemy + Marshmallow + a clean blueprint structure that scales to many endpoints.
Python
26 specialists
From data pipelines to ML inference and back

Mobile
4 technologies
Flutter
13 specialists
One codebase, two stores, zero compromise on feel
BLoC architecture, native channels for the 5% the framework can't reach, and a CI that ships to both stores.

Kotlin + Compose, on every screen size that matters
Jetpack Compose UIs, Coroutines + Flow data layers, and Play Console release tracks managed properly.
How we pick
Choosing a stack is an engineering decision, not a fashion one.
The stacks above aren't a marketing menu. They're the four-step gauntlet every engagement runs through before a single PR opens.
Step 01
01Audit constraints
Team skills, hiring market, runtime budget, infra you already pay for. The stack lives inside these.
Step 02
02Pick the boring 80%
Use the framework the docs are written for. Reach for novel tools only where they earn their keep.
Step 03
03Prove with one slice
Build one production-shaped feature end-to-end before scaling the team. Catches integration mistakes early.
Step 04
04Hand over with rails
Lint, types, CI, runbooks, on-call docs. Your team owns the code on day one, not month six.
FAQ
Things teams ask before signing the SOW.
Direct answers, no marketing prose.
Yes — a typical product engagement uses one frontend, one backend, one mobile stack, and shared design tooling. We staff cross-functional pods of 3–6 specialists.
Most adjacent stacks (Vue, Spring, Rails, Laravel, .NET) are within reach via senior engineers we trust. We'll tell you upfront if we're not the right fit instead of pretending to be.
Two questions: how much animation/sensor work does the product need, and how big is the engineering team. We've published a one-pager on the trade-off — ask and we'll send it.
Both. Roughly 60% greenfield, 40% rescuing or modernising codebases that fell behind their team. The qualify section on each tech page details when we're a good fit for either.
Yes. Named engineers, named designers, no bait-and-switch. Resumes are real and the staffing plan is contractually binding.
