Hands-on principal engineer with 20+ years across backend systems, data-heavy products, search/retrieval, internal tools, and founder-led product work. Technical co-founder, CTO/CPO, architect, fractional technical lead, and engineering owner.
I work best where the business goal is clear but the technical shape still needs senior ownership: unclear requirements, fragmented tools and data, API boundaries, retrieval quality, and architecture that has to stay understandable as the product grows. I can own the technical architecture and system shape where needed, and I stay close enough to implementation to keep latency, operability, failure modes, and tradeoffs grounded in reality.
I work across the whole product system: internal tools, backend services, data/retrieval layers, API contracts, observability, and production behavior.
Selected work:
- Fractional principal engineer / architect for ground-up KPI/analytics platform rewrite (5-person team); company later exited for ~€10M.
- Technical founder / CTO / CPO for market-intelligence SaaS: live matching of 1M+ dynamic segments against continuous on-chain/off-chain streams; ClickHouse-backed pipelines processing billions of rows/day with near-real-time downstream availability.
- Marketplace search/matching rewrite (Elasticsearch, percolator-style saved searches, high-volume notification infrastructure) while keeping the live platform in production.
Looking for freelance, contract, fractional CTO, principal engineer, or technical lead roles where one senior person needs to hold the whole system in their head.
Best fit: backend-heavy products, analytics/data infrastructure, complex internal tools, search/retrieval systems, or early-stage teams that need architecture + implementation depth without a large engineering org.
Hands-on CTO / principal engineer with 20+ years in software engineering. Technical co-founder, CTO/CPO, architect, fractional product owner, and engineering lead.
I work best at the intersection of architecture and implementation: designing data-heavy systems well, then staying close enough to the engineering to keep latency, operability, failure modes, and tradeoffs grounded in reality.
Selected work: fractional lead/architect for ground-up KPI platform rewrite; 5-person FTE team; company later exited for €10M. CTO/CPO for crypto/data product; live matching of 1M+ complex dynamic slices against continuous on-chain/off-chain metric streams; high-throughput, near-real-time latency suitable for trading workflows. ClickHouse-backed worker pipelines processing billions of rows/day while preserving near-real-time downstream availability.
Looking for freelance, contract, fractional CTO, principal engineer, technical lead, or data engineering work. Best fit: backend-heavy products, analytics/data infrastructure, complex internal tools, low-latency pipelines, or early-stage teams that need one senior person with both breadth and depth.
Willing to relocate: No, occasional travel OK.
Technologies: Backend architecture, data-intensive product systems, event-driven systems, low-latency pipelines, analytics infrastructure, search/retrieval, Node.js/TypeScript, ClickHouse, DuckDB, PostgreSQL, Redis, Elasticsearch/OpenSearch, Vue, Tailwind
