About Tanvir Ahmed
AI Engineer & Sr. Full-Stack Architect | LLM, RAG, Agents, NestJS, AWS

Job Success
Dhaka, Bangladesh - 2:35 am local time
Most developers can wire up an API call to OpenAI. That's not AI engineering.
I build AI systems that actually work in production — agents with memory, multi-step reasoning, tool use, and guardrails. RAG pipelines that retrieve the right context, not just any context. Local LLM deployments that run on your infra, not someone else's cloud. Workflow automations that handle real business logic, not toy demos.
I'm a full-stack software engineer with 6+ years of production experience, currently operating as lead backend & system engineer at an AI-first SaaS company where I'm actively building and shipping AI products — not studying them.
Right now I'm building Nodi AI — an AI-powered CRM and messaging platform — where I've designed the entire AI layer: customer support agents with persona engineering and multi language switching, RAG-based knowledge retrieval, multi-channel inbox automation (Facebook, Instagram, WhatsApp, Line, LinkedIn), and event-driven webhook architectures. I own the system end-to-end, from LLM prompt architecture to AWS ECS deployment.
I've also built and operate RentaBD, in production, a vehicle rental SaaS platform, designed from scratch — architecture, infrastructure, scaling, and business logic — solo.

AI agents & automation — Customer support agents, lead qualification bots, internal ops agents. Multi-turn memory, tool-calling, escalation logic, persona engineering.
RAG pipelines — Vector search, embedding strategies, hybrid retrieval, context window management. Built on OpenAI, Anthropic, Gemini, DeepSeek, or your own local models.
Local LLM deployment — On-premise inference stacks using Ollama, LM Studio, or custom setups with Mistral, Llama, Qwen, and others. Full privacy, no API costs.
LLM integration into existing products — Drop AI into your existing SaaS without rebuilding it. I'll design the integration cleanly and make it maintainable.
Full-stack SaaS & backend systems — NestJS/Node.js backends, Laravel APIs, Vue/React frontends, PostgreSQL, Redis queues, Docker, AWS. Production-grade, not prototype-grade.

Founders building AI-first products. Teams adding AI to existing SaaS. Businesses that need automation done properly, not hacked together. Clients who value systems that still work six months from now.
I communicate clearly, deliver in structured milestones, and don't disappear once the first version ships. I've worked with clients in Ireland, Australia, the UK, and India — async communication is second nature.
