Full Stack Developer & Systems Architect

$ With 10+ years of hands-on engineering across the full stack — from bare-metal Linux VPS provisioning to shipping production-grade cross-platform apps — I architect and deliver scalable, maintainable solutions across web, mobile, and desktop.

$ My core stack spans PHP/Laravel, Django/FastAPI, Flutter, React.js, Node.js/Express with deep database expertise in MySQL and PostgreSQL. I design RESTful and event-driven APIs, implement CI/CD pipelines, and integrate third-party services including payment gateways, SMS, email, and AI/LLM backends.

$ On the infrastructure side, I manage LAMP stacks, Contabo VPS, and serverless deployments (Vercel, AWS Lambda). My AI integration work spans LangChain, HuggingFace transformers, and prompt engineering for LLM-powered production applications and intelligent assistants.

$ Whether you need a technical lead for a greenfield project, a senior dev to un-block a complex sprint, or an architect to design a fault-tolerant multi-platform system — I ship reliable, high-quality code.
