About Me

Hello! I'm Istiak Ahmed, a Product-focused Founding Engineer with 2+ years of building backend systems. I specialize in iterative architecture for evolving business needs and privacy-first design.

I build scalable backend systems with a focus on extensibility and security. My experience includes designing database architectures for 50+ tables, implementing CI/CD pipelines for rapid deployments, and integrating privacy-focused solutions like client-side encryption. I thrive in startup environments where I can architect systems from the ground up while ensuring reliability through rigorous testing.
