What I'm looking for

I’m looking for an engineering role where I can own backend architecture and ship end-to-end LLM/ML and distributed systems—especially self-hosted AI, RAG, and practical IoT integrations—with strong engineering practices and growth.

I’m a backend-focused software engineer with hands-on experience building production-grade distributed systems, LLM-powered applications, and ML-integrated APIs. I’ve shipped multi-tenant SaaS and AI solutions—from architecture through deployment on K3s and Raspberry Pi clusters.

At Tunemax, I architected and maintained a multi-tenant B2B CRM with role-based access control (RBAC), quote management, FX rate handling, and automated task scheduling built on NestJS + PostgreSQL. I designed a K3s-based microservices environment (dev/prod namespaces, Nginx reverse proxy, Cloudflare Tunnel), built Puppeteer PDF reporting with Metabase BI, and set up a self-hosted Jenkins CI/CD pipeline while addressing real-world deployment issues.

My work also extends into applied AI and research: I initiated a federated learning research stream and contribute NLP preprocessing and model evaluation under academic guidance. On the project side, I deployed a fully private self-hosted LLM assistant on Raspberry Pi using llama.cpp + TinyLlama with quantization, built hybrid NLP routing (exact-match + LLM fallback), and created IoT systems like an ESP32-based milk analyser streaming to ThingSpeak—automating measurement and improving traceability.
