RB-Development is a one-person engineering studio building mobile apps, websites, and backend systems — with an obsession for security, correctness and maintainability.
Every project is handled end-to-end — from the first conversation to deployment and long-term maintenance. No hand-offs, no diluted accountability.
Native Android apps built with Kotlin and Jetpack Compose. From concept and UX to Play Store release, including offline-first architectures and background sync.
Fast, accessible, no-framework-bloat websites and web applications. Built to score well on Lighthouse, work offline, and load on the weakest connection.
High-performance, memory-safe backend services in Rust. Axum, Actix, Tokio — built for predictable latency, strict typing, and honest error handling.
Code review, threat modeling, and remediation guidance. Focused on realistic attackers, real-world trade-offs, and security you can actually ship.
An honest second opinion. Independent review of a codebase or architecture — what's healthy, what's risky, and what it would cost to fix.
Ongoing support for apps and services already in production. Bug fixes, dependency upgrades, incident response, and feature work on a retainer.
A small studio can move fast — but speed without rigor is just technical debt arriving early. Here's how projects actually run.
Before writing code, we talk. What does success look like? Who is this really for? What's been tried? A project that starts with a clear problem statement is already half-solved.
You get a Git repository, a staging environment, and a short weekly update from day one. No "big reveals" — you see the progress, the trade-offs, and the code as it's written.
Launch is the start, not the end. Every project comes with a written runbook, clear handover notes, and the option of a maintenance retainer — because the first production bug is always worse at 3am than at 3pm.
Boring technology where it belongs. Modern where it earns its keep. Everything here has been used in production — not just on a weekend.
RB-Development is run by a single engineer who cares about the whole stack — from the low-level byte to the pixel the user taps. No account managers, no junior hand-offs, no marketing varnish.
Most work comes from word of mouth: teams that want a dependable engineer who can own a feature, a service, or an entire product without needing to be managed. If that sounds like what you're looking for, say hello.
