Ramshad Rahman

I’m a results-driven Senior Full Stack Developer with 6+ years of experience architecting and delivering scalable ERP and web-based solutions. I focus on building reliable platforms that grow with real customer needs, combining strong product ownership with hands-on engineering.

At Eallisto Informatics, I led the transformation of a CRM into a full-featured ERP platform—owning core architecture and business logic—and scaled the product from 25 to 500+ clients with 80% retention. I designed and implemented a complex inventory management system, built a partner portal with workspace provisioning, and integrated payment gateways to support seamless subscription management.

On the platform side, I overhauled authentication from session-based to token-based security, implemented session monitoring to clear stale sessions, and developed REST-consumed services like custom PDF generation and an internal URL shortener. I also integrated third-party applications via REST APIs to keep field sales data in sync in real time, and built internal ERP monitoring tools to proactively detect and resolve production issues.

I’m known for owning complex technical challenges and mentoring junior developers by enforcing best practices across the product. Beyond development, I bring a complementary background in IT infrastructure and systems administration, which strengthens how I design, operate, and support production environments.
