Manish Rana
Founding Full Stack Engineer
Zero-to-One Products · Fintech · SaaS · AI
Founding engineer with 7+ years building products from 0→1 across fintech, blockchain, SaaS, AI, and workflow automation. Repeated day-one / early-team ownership: architecture, shipping, auth, payments, APIs, and production infrastructure — not just tickets.
Comfortable wearing product + eng hats, iterating fast with founders, and owning systems end-to-end from MVP through scale. Startup strengths: zero-to-one delivery · full-stack ownership · product judgment · ambiguous problem-solving · shipping under constraints.
Outside of code, I recharge by traveling, exploring nature, and spending time with my kid—my best source of inspiration.
