Building an AI product? Launching a SaaS? Need someone who can take ownership instead of simply writing code? I am a Full-Stack AI Engineer with 8+ years of experience helping startups and growing businesses design, build, and scale production-ready software. From AI-powered applications and SaaS platforms to workflow automation and complex integrations, I focus on building products that solve real business problems not prototypes that need to be rebuilt six months later. I have delivered 20+ production projects, improving application performance by 40%, reducing production bugs by 50%, and helping teams ship faster with scalable architecture and clean, maintainable code.

I've built LLM orchestration layers with retry logic, streaming responses, and guardrail systems, input classifiers, output filters, and rate limiting, for conversational AI modules that handle real user sessions, not demo scripts. ⚡Async AI processing pipelines using BullMQ & Redis job queues, turning raw input (call transcripts, uploaded documents) into structured, validated output on a queue architecture built to survive production load. 🌐Browser automation & AI document processing: Python and Playwright engines that navigate dynamic third-party websites, paired with GPT-4o Vision to extract structured data from scanned PDFs and images for downstream automation. 💡Daily AI-native development workflow: Claude Code, Cursor, Lovable, and Windsurf, used inside real client codebases to accelerate delivery, not just referenced as buzzwords. 🧠RAG pipelines, vector search (Pinecone), n8n, Automation, LLM Integration, and LangChain-based AI agents for document-grounded chat, retrieval, and knowledge assistants. 🤖AI agents & workflow automation | LangChain/LangGraph agents, RAG pipelines, n8n automations that replace manual processes 🏗️ 𝐈𝐍𝐃𝐔𝐒𝐓𝐑𝐈𝐄𝐒 𝐈'𝐕𝐄 𝐁𝐔𝐈𝐋𝐓 𝐅𝐎𝐑 SaaS and workflow-automation platforms, Healthcare and HealthTech (patient/provider data platforms), iGaming and affiliate MarTech (GPT-driven, SEO-heavy platforms), FinTech, EdTech, and enterprise internal tools including CRM/WMS systems. 🎯 𝐖𝐇𝐘 𝐂𝐋𝐈𝐄𝐍𝐓𝐒 𝐊𝐄𝐄𝐏 𝐌𝐄 𝐎𝐍 𝐑𝐄𝐓𝐀𝐈𝐍𝐄𝐑 → I own backend, frontend, AI integration, and deployment under one contract. No handoff gaps between a frontend developer, a backend developer, and an "AI person" one accountable owner, start to finish. → I've delivered inside hard fixed-price sprints, a 3-week, 5-milestone backend-plus-AI build with zero missed deliverables, and inside open-ended, long-term maintenance contracts on live production codebases still generating revenue today. → I use Claude Code, Cursor, and Lovable inside real client codebases to move faster, without leaving behind code that can't be handed to another developer six months later. → I ask what the business outcome is before I choose the stack. The right architecture is the one that ships and holds up under real usage, not the most technically interesting option on the table.
