Iโm a senior AI systems and full-stack engineer with deep experience designing, building, and shipping production AI products end to end. I specialize in turning complex ideas into reliable, scalable systems that actually work in the real world.
My background spans AI/ML pipelines, backend systems, and modern web applications. Iโve led and contributed to projects involving large language models, multimodal analysis (video/audio), RAG architectures, automation pipelines, and subscription-based SaaS platforms. Iโve worked both as a freelancer and as a lead engineer on internal AI products used by real customers at scale.
What I do best is bridge the gap between research and production. I donโt just prototype. I design systems that handle edge cases, cost constraints, performance targets, and long-term maintainability. That includes API design, data modeling, infrastructure decisions, and clear handoffs to frontend or product teams.
Core strengths:
โ AI, Agents & LLM Systems: RAG pipelines (LangChain, Pinecone), Model Context Protocol (MCP), OpenAI/Gemini/Whisper, and custom evaluation frameworks.
โ Backend Engineering: Java Spring Boot, .NET, Python, Ruby on Rails, Node.js, PHP.
โ Workflow Automation: Complex orchestration using n8n and Zapier to connect AI agents with business logic.
Full-Stack Apps: React, Next.js, TypeScript, .NET, Java, PHP, Ruby on Rails, Supabase, Stripe, and secure authentication flows.
Data & Infrastructure: Postgres, MySQL, Docker, AWS, and CI/CD pipelines.
Iโm especially strong in AI products that involve:
โ Advanced RAG: Retrieving context from complex datasets (PDFs, Databases) for accurate LLM responses.
โ Multimodal Analysis: Processing Text, Audio, and Video inputs.
โ Structured Outputs: ensuring JSON reliability and strict evaluation logic.
โ Cost-Aware Workflows: Optimizing token usage and latency.
โ Human-in-the-loop Systems: Designing approval flows for critical AI tasks.
Clients hire me when they need someone who can think like an engineer, a product owner, and a business operator at the same time. I ask the right questions up front, communicate clearly, and deliver systems that are built to last.
If you need help designing a robust RAG system, stabilizing a backend, shipping a full product, or untangling an automation workflow thatโs gotten too complex, I can help.
Happy to jump on a call and talk through your problem before writing a single line of code.
