Background
About
I'm Edward Sarker, a senior technologist with deep experience across full-stack engineering, security architecture, and technical leadership. I've built and scaled systems for startups, guided engineering teams through critical transitions, and hardened security postures for organizations handling sensitive data.
My consulting engagements are designed to be self-contained: clear scope, measurable outcomes, and knowledge transfer that leaves your team stronger than when I started. No long-term dependency. Just results.
