Zain Ramzan

I’m a Senior Software Engineer with 6+ years of experience architecting and delivering scalable web applications for enterprise clients. I’m also a founding engineer who built a real estate platform from scratch, supporting 1,000+ daily users across two countries.

In my current role at Intagleo Systems, I take ownership of OMNI, a digital building management platform serving 150+ buildings and 500+ enterprise users. I lead and mentor a team of 4 engineers, set technical direction through code reviews, and integrate AI-native development tools to improve AI-assisted code generation and review productivity by 10%.

I’m especially proud of my focus on performance and security. I implemented an S3 caching migration layer (reducing database read load by 80–95%), refactored shared utilities to reduce bundle size by 43% / 29% / 28%, and improved heap efficiency by 17.3% (total) and 13.4% (used).

On the security side, I conducted penetration testing with OWASP ZAP and remediated 300+ vulnerabilities—eliminating 100% of high-risk and 90% of medium-risk issues. I also built and deployed an IdP-agnostic FastAPI SAML 2.0 service as an AWS Lambda to accelerate enterprise onboarding from days to minutes.
