Summary
🤩
Rockstar🎓
Top SchoolDariusz Lasecki is a Senior Software Engineer and Technical Lead with nine years of experience building high-performance ML, quantum, and geospatial systems from research prototypes to production at DeepMind, IBM Research, TomTom and beyond. He helped productionize AlphaFold 3 and the AlphaFold Server, architected large-scale protein folding pipelines and TPU/ GPU autoscaling, and previously drove foundational quantum computing contributions to Qiskit used by 100k+ users. His background in combinatorics and optimization informs pragmatic, mathematically rigorous solutions—from a continental-drift service that improved HD map accuracy tenfold to quantum algorithms that cut qubit and compute costs dramatically. Comfortable across Python, C++, JAX and distributed systems, he bridges research and engineering to ship scalable, mission-critical platforms. An often-overlooked thread through his career is repeated success turning research proofs and prototypes into robust open-source and cloud-native production software.
