I build production AI systems — Agentic AI backends, multi-LLM routing, MCP architectures — and ship full-stack platforms that scale. 15+ years delivering for US & EU clients.
Deep expertise across the full AI + full-stack spectrum — from LLM orchestration to production infrastructure.
Production systems built from zero — not tutorials or side projects.

The fastest way is to email sirinibin2006@gmail.com or connect on LinkedIn with a brief description of your project or role. I respond within 24 hours. After an initial call to scope requirements, I provide a written proposal with timeline, rate, and contract structure. For short-term engagements I typically work through Startup Tech Consultancy LTD (UK Company No. 12479922), which simplifies invoicing for EU, GCC, and US clients. Engagements can start within 1–2 weeks of agreement.
Day rates range from £600–£800/day for Golang backend engineering and £700–£900/day for AI engineering (LLM integration, agentic AI, FastAPI). Full-stack and React roles are typically £500–£750/day. I am available for immediate start on freelance and contract engagements. I work remotely across GMT, CET, GST, IST, and PST timezones — no location constraint for EU, Middle East, India, or North American clients.
I build production AI systems using OpenAI GPT-4o, Anthropic Claude (with MCP), Google Gemini, and Groq. My specialities are agentic AI (multi-step tool-using agents), RAG pipelines with pgvector and Pinecone, voice AI using OpenAI Realtime API and ElevenLabs, and MCP server authoring for Claude Desktop integrations. I use Python FastAPI for AI backends and Golang for the orchestration layer. I have delivered production AI systems including the AI Chat Bot (StartPOS multi-LLM assistant) and multiple client LLM integrations.
Yes. I built ZATCA Phase 1, Phase 2, and B2B clearance compliance from scratch for StartPOS — including ECDSA cryptographic signing, TLV-encoded QR code generation, UBL XML invoice generation, and B2B clearance integration with the ZATCA Fatoorah API. The solution has a zero-rejection rate in production. For new client projects I can typically deliver a working ZATCA Phase 2 integration within 4–5 weeks of engagement start, including ZATCA-certified testing and sign-off.
I have built Golang systems in production for 8+ years. The most significant is StartPOS — a full ERP/POS platform with 8 Go microservices handling 10,000+ daily transactions on AWS EC2, with MongoDB, Redis, and JWT authentication. I also built the AI Chat Bot orchestration layer in Go — routing between 5 LLM providers with sub-500ms response time. My Go work covers REST APIs, gRPC/Protobuf, goroutine-based concurrency, Docker multi-stage builds (images under 20MB), and Kubernetes deployments.
