I have worked across CTO, Tech Lead, Business Analyst, Product Owner, and Project Manager responsibilities, with a strong focus on turning business goals into practical technical roadmaps. I co-founded Simpli and helped grow it from a two-person startup into a 30-person software house that delivered more than 50 products for startups and enterprise clients. My background combines hands-on engineering with leadership. I enjoy architecture, requirements discovery, solution design, documentation, and aligning delivery with real business needs. In recent years, I have also been deeply involved in blockchain, smart contracts, DeFi protocols, and AI-assisted development workflows, while staying close enough to the code to maintain technical credibility. I value listening, delegation, collaboration, and mentoring. I am looking for a role where I can own both the technical direction and the people side of a team.
