AI Product Engineer and Founder

Self Employed • Lavoratore autonomo

Sep 2022 - Present • 4 yrs 1 mo

With the help of agentic workflow and vibe coding I ship complete products solo - mobile, web, backend, infrastructure, store release - in the time a team usually spends scoping. Recent work: a WebRTC video consultation app on iOS and Android, a multi-tenant SaaS with per-tenant isolation, a white-label factory that generates branded Android and iOS builds from one config file, and AI agent products with RAG and multi-provider LLM support. Prompt engineering and AI-assisted development do the typing. Judgement about structure, data models, edge cases and what the model quietly got wrong is what you are actually hiring. Flutter, Kotlin, Swift, Node.js, Python/FastAPI, React/Next.js, PostgreSQL, Docker. If you have been burned by AI-generated code that looked right and fell apart, that is the exact gap I fill.

Senior Software Engineer, Android

Portonics Limited • Full time

Sep 2021 - Aug 2022 • 11 mos

Android engineering on a consumer app with 10M+ users. Introduced Clean Architecture to the codebase - clear data, domain and presentation layers, testable use cases and a dependency-injected service layer - so features could ship at that scale without regressions. Kotlin, modern Android tooling, and coaching the team through the new structure.

Senior Software Architect

BJIT • Full time

Jan 2021 - Aug 2021 • 7 mos

Brought onto a React Native project that was at risk of cancellation and architected the WebRTC solution that unblocked it - real-time audio and video working across both platforms. Also rebuilt a search feature from a linear scan to a Trie-based prefix lookup, taking it from O(n) to O(k).
