I design, build, and ship production-grade mobile apps and enterprise desktop POS systems. Solo. From scratch. End to end.

Every project below was designed, developed, and deployed by me alone. No team. No outsourcing.

Systems engineer.
Solo builder.

I don't just build screens. I build the whole stack: database schemas, background sync engines, native device bridges, printing protocols, and the UI — all in one codebase.

My background is in building complete, offline-resilient desktop POS systems alongside high-performance mobile apps. The common thread: I own every layer. When the Bluetooth printer drops, I wrote the retry logic. When the receipt format changes, I wrote the ESC/POS renderer.

I take full responsibility for every product I ship: schema design, state architecture, CI/CD pipeline, native platform configuration, and App Store release workflows.

5 Complete systems built solo

How the systems get built.

A real hierarchy — not a wall of badges.

Core Frameworks

  • Flutter & Dart Cross-platform mobile (iOS, Android) and desktop (Windows) — single codebase, native performance.
  • C# / Windows Native Low-level platform bridges: device discovery, USB sockets, print spoolers.
  • Node.js / SQL REST APIs, scheduled jobs, and relational database schemas.

Hardware & Integration

  • ESC/POS & Printing Thermal printer protocol implementation over USB and TCP/IP.
  • Offline-First Storage SQLite, Hive, and Isar with multi-threaded background sync strategies.
  • Method Channels Custom native platform wrappers bridging Flutter to Win32 and Android APIs.

DevOps & Delivery

  • CI/CD Codemagic, Fastlane, and GitHub Actions for automated builds and store uploads.
  • State Management BLoC pattern, Riverpod, Provider — chosen by complexity, not by habit.
  • APIs & Realtime RESTful design, JSON parsing, Firebase, and WebSocket synchronization.

How I build your product.

From first conversation to App Store listing, I own every phase.

01
Discovery & Architecture

I map database schemas, local caching strategies, hardware integrations, and sync models before writing a single widget. Architecture decisions made early prevent rewrites later.

02
Core Engine

Building offline databases, background sync, printer protocol engines, payment gateway bridges, and native platform wrappers. This is where the invisible work happens.

03
UI Implementation

Coding smooth, responsive interfaces at 60 FPS. RTL-first where required. Custom animation systems. State management chosen for the use case, not by default.

04
Release & Support

CI/CD pipelines, automated tests, app store assets and metadata, staged rollouts. I handle the deployment, then stay available for post-launch issues.

Let's build something precise.
