> Lead Software Engineer | Web3 & Blockchain | Python · Distributed Systems | Building on Tezos

Location: London, England, United Kingdom
Profile: https://flows.cv/vitaliinazarov

I'm a software engineer with 13+ years of experience across Web3, data engineering, bioinformatics, and ML - spanning startups, enterprise, and research.
Currently at trilitech, I build on the Tezos blockchain. Previously at FactSet, I led a team delivering ESG data pipelines at scale. Before that, I spent 7 years at OnTarget Labs across various projects in pharmaceutical modelling, ML/OCR systems, and e-commerce platforms.
My background is unusually broad: I hold a degree in Computational & Applied Mathematics, studied Bioinformatics, have shipped production systems in Python, C#, C++, and more. I gravitate toward technically complex problems, especially where engineering meets science.
Open to senior/staff engineering roles in Web3, data infrastructure, or deep-tech.
