I design and ship AI products, agentic systems, and reliable full-stack software for founders, CTOs, and engineering teams.

For 8+ years, I have built and modernized products across backend systems, frontend experiences, automation, and delivery infrastructure. Today, I combine strong engineering fundamentals with AI-native workflows to increase throughput, shorten feedback loops, reduce avoidable errors, and launch faster without compromising quality or judgment.

• AI agents and LLM systems: Tool-using agents, multi-agent workflows, retrieval, evaluations, guardrails, and human approval flows.
• AI SaaS and MVPs: From an ambiguous idea to a maintainable, testable product with a clear path to production.
• Vibe-code rescue: Turning fragile AI-generated prototypes into secure, structured, production-ready applications.
• Agentic modernization: Using AI-assisted codebase discovery, planning, implementation, and validation to safely evolve existing systems.
• Workflow automation: Removing repetitive work and connecting systems around real business processes.
• Technical partnership: Helping founders and CTOs make sound architecture, scope, and delivery decisions.

I use AI as an engineering multiplier, not a substitute for accountability.

My workflow combines structured context, specialized agents, automated checks, tests, evaluations, code review, and human validation. This lets me explore faster, implement in parallel, catch problems earlier, and preserve the reasoning behind important decisions.

The goal is not to generate more code. The goal is to ship the right system sooner, with less risk.

AI Agents and LLM Systems: Tool-using agents, multi-agent workflows, MCP, RAG, structured outputs, function calling, human-in-the-loop systems, evaluations, guardrails, and AI observability
