What I'm looking for

I’m looking to build production-grade products end to end—especially multitenant SaaS, APIs, and LLM-powered automation—where I can keep shipping independently, deepen backend reliability, and work with practical engineering teams that value ownership.

I’m a full-stack developer and architecture student with hands-on experience designing and shipping production software. I focus on Python, JavaScript/TypeScript, and SQL-driven systems, with strong fundamentals in data structures and REST API design.

I’ve independently architected and extended a multitenant SaaS platform using Flask, including subdomain-based routing middleware, per-tenant templating, Celery/Redis background processing, JWT authentication, and Docker Compose deployment. I also added PWA support with a dynamic manifest and per-tenant service workers for a mobile experience.

My projects extend into trading and AI: I built a full-stack forex intelligence SaaS that combines currency-strength analysis with news-driven trade signals across 28 currency pairs. I’ve also designed algorithmic trading systems (MQL5/Pine Script) with state tracking, ATR-based risk management, and Telegram alerts.

More recently, I’m building LLM-powered automation pipelines using local tooling (Ollama) and prompt engineering, including video content generation with Edge-TTS, MoviePy, and yt-dlp, plus a Python-based local assistant (“Nyx”) with system-tool integration, voice I/O, and persistent memory. I enjoy scoping, building, and deploying reliably—end to end.
