Startup Speed

Enterprise-Grade Reliability

Who am I?

I’m a freelance full-stack engineer with 11+ years of hands-on experience in B2B SaaS and fintech. Fully remote by default, I’ve led and mentored distributed teams across multiple time zones, building trust through clear, proactive communication.

Along the way, I’ve made my share of mistakes—over-architecting early prototypes, underestimating integration complexity, and sometimes shipping without enough tests. Those lessons drove me to embrace iterative delivery, rigorous QA, and transparent client check-ins, so every release adds real value without surprises
