Full-Stack Software Engineer — Automation & AI
I build end-to-end digital products and automate complex workflows. Pragmatic engineering, AI-augmented by design — from architecture to production.
I'm a full-stack software engineer focused on building end-to-end digital products and automating complex workflows: robust backend architectures (Node.js, PHP, Python) and high-performance mobile applications (React Native).
My approach is pragmatic — I don't believe in reinventing the wheel, but in solving business problems efficiently. I integrate AI and agent-based workflows into my daily process (Spec-Driven Development), which lets me accelerate architecture design, refactor code rapidly, and build deterministic data pipelines with a high level of technical quality.
Recently I've designed Human-in-the-Loop automation systems where local LLMs extract, normalize, and learn from data under strict quality safeguards — and I've built and scaled FightersTech, an international mobile platform, from decoupled architecture and GDPR compliance to production deployment on the App Store and Google Play.
Founder & Lead Engineer · 2020 — Present
International mobile platform for the fighting game community, live on the App Store and Google Play. Decoupled architecture (Strapi, PostgreSQL, Kafka), a 9-stage Python automation pipeline with local LLMs (OCR, analyze–verify pattern, confidence scoring) running unattended 24/7, and GDPR compliance designed from the architecture level.

Two integrated systems delivered for a client in the maritime education sector: a web platform on Hexagonal Architecture (PHP 8.3) with an idempotent, rate-limited REST API, and an AI-driven catalog automation system (Python) with mandatory human review, supervised learning from corrections, and 0.90 confidence thresholds. Built entirely with Spec-Driven Development — full code-to-spec traceability.
Open Source · TypeScript
Production-ready NestJS backend baseline: multi-provider JWT/OIDC authentication (Auth0, Supabase, Keycloak), RBAC guard chain, 12-phase GDPR export & deletion pipeline, rate limiting with Redis fallback, and 13 E2E suites with real RS256 cryptographic validation.
