Summary
👤
Senior🎓
Top SchoolCallum Leach is a Principal Engineer and Tech Lead in MLOps with nine years of hands-on experience building high-throughput data platforms, distributed systems, and resilient production infrastructure across startups and enterprises. He has led 0→1 transformations, architected zero‑copy data lakes with Spark integrations (100MB/s throughput, 100M+ rows/s ingestion), and reverse-engineered Databricks toolchains into Go for dramatic performance gains. A prolific open-source contributor to Spark, Go, Databricks and Elixir ecosystems, he combines deep systems-level curiosity with practical product sensibility—having helped secure over $150M in capital through home-grown distributed systems. Comfortable advising C-suite stakeholders, he also drives SOC2/GDPR-compliant infra, CI/CD and network designs while coaching teams to work asynchronously at scale. Outside work he coaches kickboxing to kids and is training as an ultramarathon runner, a reflection of the same endurance and discipline he applies to high-pressure engineering rescues.
