About Me

I'm a Full Stack Software Engineer who transitioned from Mechanical Engineering into building production-grade web systems. What started as self-directed curiosity turned into end-to-end ownership of live platforms used by real users.

I specialize in designing and building scalable SaaS systems — secure REST APIs, subscription and role-based access control, hybrid database design, real-time infrastructure and AWS deployments. I apply SOLID principles, clean architecture and testing practices to every system I build.

Currently a Founding Software Engineer at MedB Connected Care LLP, where I lead backend architecture, frontend architecture, database design, API design and production deployment for a live healthcare SaaS platform serving real users.

Work Experience

Jan 2025 — Present
Founding Software Engineer
MedB Connected Care LLP Remote ● Active

Built and operated a production-grade healthcare SaaS platform from scratch (0→1), serving as the primary technical decision-maker — defining architecture, database strategy, authentication and deployment workflows independently.

  • Designed multi-tenant, subscription-based access control across doctors, patients, clinics and administrators (4+ user tiers)
  • Architected hybrid persistence: PostgreSQL for transactional consistency, MongoDB for audit logging and high-volume operational data
  • Implemented caching and query optimizations, reducing average API response time by 35%
  • Streamlined onboarding workflows, reducing new user setup time by 40%
  • Engineered real-time notification infrastructure via WebSockets with multi-channel failover (in-app, email, WhatsApp)
  • Deployed on AWS EC2 with Nginx and PM2, maintaining >99% uptime with stable failure recovery
  • Established centralized logging, monitoring and audit visibility across the full system
