🎯 Professional Summary

20+ years leading R&D and platform architecture in safety-critical, ISO-certified domains. Track record spans medical devices, semiconductor EDA, and SaaS platforms β€” built and certified from zero.

Core Impact:

  • Designed SDLC and quality systems compliant with IEC 62304, ISO 13485, ISO 14971 β€” patterns transfer to ISO 26262, DO-178C, IEC 61508, and ISO 27001
  • Led 4 international regulatory approvals (FDA 510(k), CE, KFDA, CCC) with 1,200+ pages of auditor-ready traceability documentation
  • Orchestrated 10+ microservices in C++, Rust, Go, Python (RabbitMQ/Redis) at Pozalabs (audio SaaS)
  • Achieved 2x throughput and 50% latency reduction on medical imaging systems at Ray
  • Built 4+ production systems from blank repo to certified release across 2 IPO companies

Since March 2026, CTO at Flonics β€” a Seed-stage medical device startup preparing for its Pre-A round β€” owning development, operations, and management across all projects with a lean team.

πŸ”­ Currently

CTO at Flonics (since 2026.03) β€” a Seed-stage medical device startup preparing for its Pre-A round, running lean. Owning development, operations, and management across all projects while leading R&D for medical imaging-based blood flow diagnostics, with ISO 13485 / IEC 62304 processes applied from day one. Maximizing lean-team leverage through an automation-first operation: reporting generated from GitHub issue/PR records, CI/CD test automation, SonarQube security gates, AI code review, and AI-driven triage and reporting of findings β€” extending to regulated documentation for device certification, verified through human approval gates and automated traceability audits.

Long-term interest: CTO / Head of R&D / Research Director roles in any ISO-certified domain β€” automotive functional safety, industrial IoT, defense/aerospace, or regulated SaaS. The common thread is building rigorous engineering organizations under standard-driven constraints, not the specific industry vertical.
