Full Stack Software Engineer

Building production-scale applications for startups, SaaS companies, and international teams

I'm Abubakar Sohail, a Senior Full Stack Software Engineer focused on building scalable backend systems for SaaS and startup environments.

My work centers around API-first architectures, real-time collaboration, and performance optimization in production systems. At Devsinc, I help architect multi-tenant platforms, reduce latency, and ship features used globally.

I work closely with product and engineering teams to turn business requirements into reliable software—not just working code.
