### Hands-on CTO | Lead Software Engineer | 15+ years I build products end to end and still write code most days. I'm the CTO at Hexis, a sports nutrition platform trusted by 40% of the professional peloton at the Tour de France and 50% of the Premier League. I joined as a senior engineer, rebuilt the core data model so multi-day queries went from several minutes to under 700ms (a key factor in closing a $2.1M seed round), moved the platform to GCP and drove our SOC 2 audit. In our CEO's words, I was instrumental in building a product that delivered a 300%+ increase in ARR and found product-market fit. Through Toptal I've worked as a lead engineer and fractional CTO. For an AI startup in financial due diligence I built an agentic RAG platform that indexed 10M+ pages and scored 100% on the Vectara RAG benchmark. I led engineering on Fashion Nova's React Native app on the Shopify Storefront API, and owned HIPAA-compliant auth, payments and audit logging for a US healthcare company. Earlier I led a team of nine at Verizon Media/RYOT on a 3D content tool used by the NFL, HuffPost and Yahoo. Before that I worked on ISSUU's backend, which served 100M+ users a month, and built the SDK and developer marketplace for Danske Bank's District platform. What I work with: TypeScript, Node.js, NestJS, React, Next.js, React Native, Python, Go, PostgreSQL, GraphQL, GCP, AWS, Docker, Kubernetes, Pulumi, Terraform, and LLM tooling like LangGraph, LangChain, LangSmith, OpenAI, Anthropic and Gemini.

I have a long-standing passion for coding, and have received great feedback as tutor & mentor over 10+ years as a Software Engineer. I have an expert mastery of Javascript, Typescript, C#, GIT, CSS, HTML, and have implemented solutions at all levels of the tech stack. I feel strongly that software is built for people, and not the other way around: I strive to provide solutions that meet people where they are. As a programming language enthusiast, I have explored many languages & paradigms, both in terms of practical use and underlying mechanisms. This has given me a uniquely strong ability to: implement solutions that closely match human mental models; understand solutions apart from their coded form; spot incidental complexity in code; deconstruct and re-implement complex code-bases (e.g. when migrating legacy software). As a tutor and mentor, these experiences enable me explain things in human terms, and empathize with the gap between technology and the human mind. My favorite experience as both a software engineer and mentor, is that spark of discovery or understanding while walking someone (or vice versa) through a problem or explanation. Other interests: Piano, Stargazing, Hiking, Camping, Yoga, Mindfulness, Reading, Origami, Retro gaming, Sci-fi, Horror, Dad jokes, Playing with my kids & my dogs.
