About

I build complex AI and software systems from architecture to production - spanning backend platforms, cloud infrastructure, LLM workflows, developer tools, and hardware-software systems. I founded Unfold AI, an AI developer platform that reached 100,000+ installs organically. I built production systems around code understanding, debugging workflows, cloud infrastructure, usage-based billing, and repo-aware AI. In parallel, I led architecture and development of terahertz imaging systems combining acquisition software, embedded control, signal processing, optics/laser systems, and AWS-based analytics. I’m strongest where product, architecture, and deep technical execution meet: taking ambiguous, complex systems from early design to production, leading hands-on development, and building reliable platforms across software, AI, cloud, and hardware boundaries. Open to senior/principal engineering, founding engineer, AI platform, backend/infra architect, and technical leadership opportunities.

    Founded and built Unfold AI, an AI developer platform for code understanding, debugging, repo-aware automation, and agentic development workflows. The product reached 100,000+ installs organically, 400+ weekly active users, and hundreds of paying customers/subscribers. Built the platform end-to-end across VS Code extension development, backend architecture, cloud infrastructure, billing, authentication, observability, and LLM-powered developer workflows. Key work included: • Built a repo-aware AI system for codebase understanding, debugging, refactoring, and workflow automation across large repositories. • Developed IDE-native debugging workflows including terminal error capture, stack-trace analysis, root-cause explanations, and one-click fix suggestions. • Architected and deployed the production backend on AWS using TypeScript/Node.js, ECS/Fargate, PostgreSQL/RDS, SQS, CI/CD, observability, and usage-based billing. • Built codebase indexing and context retrieval infrastructure for working with repositories beyond model context limits. • Launched UnfoldCI, an AI-powered GitHub Marketplace product for detecting, analyzing, and fixing flaky tests across CI pipelines • Integrated with GitHub Actions, PR comments, Checks API, and AI-generated pull requests for automated test remediation. Unfold AI focuses on building supervision, debugging, and automation infrastructure for AI coding agents and developer workflows.
