I'm a Senior Software & AI Engineer with 6+ years of experience delivering end-to-end AI systems, from concept to production. I specialize in rapid execution: I can build a fully working AI-powered MVP/POC within 24 hours, and I've shipped the production systems behind that kind of prototype too. Three things I do: 1) AI AGENTS & LLM SYSTEMS - Enterprise document-AI platform on multi-region AWS (sync API + async SQS worker pool): OCR pipeline, document classification with pgvector, schema extraction and form filling with LangGraph agents, fraud and handwriting detection, summarization, citation validation and hallucination checks, text-to-SQL - Deep research agent over ingested documents (Plan-and-Execute, Supervisor-Researcher, RAG + code execution + file generation) - Influencer outreach agent (research + outreach + sales conversation + human in the loop) - Excel processing agent (pandas code generation with structured output and self-reflection) - Text2SQL (ReAct agent with tools) - Real-time voice agents (speech-to-speech pipelines with LangGraph) - Social media content creation system (content creation + quality analysis) - Complex ML use cases using GNNs, RL, CNNs, and more 2) AGENTIC VIDEO PRODUCTION AT SCALE I built agent-driven creative platform. You brief the AI in chat, it plans the piece, generates images, video and audio onto a collaborative canvas, then composes the final ad, reel or film with captions, transitions and music. I also run this pipeline for my own YouTube channels, producing long-form documentaries and shorts end-to-end with AI, so I know what actually holds up in front of an audience, not just in a demo. 3) FULL-STACK APPS SaaS MVPs, dashboards, internal tools, client portals, streaming chatbots and automations. Production deployments primarily on AWS, with strong support for other cloud platforms. Alongside the AI work, I deliver the workflow, API, UI, deployment and automation needed to make it usable. If you need someone who can: ✔ Understand your idea quickly ✔ Architect the right AI approach ✔ Build and deploy fast ✔ Communicate clearly, no jargon ✔ Deliver reliable, scalable results ...I'm here to help.
