Sherafgan Bhatti

I’m a Senior Software Engineer with 4.5 years of experience building scalable full-stack web applications across the insurance, HR, and logistics industries. I’m known for owning features end-to-end—from architecture through production—with a consistent focus on performance, reliability, and maintainable code.

At DevsInc, I architected and maintained Rails and React/Next.js applications for US insurance clients, improving performance by 30–40% using Redis caching and eliminating N+1 queries. I built a PostgreSQL multi-tenant architecture supporting 100+ insurance companies on a single instance with complete data isolation.

I’ve delivered complex integrations and production reliability improvements, including a RingCentral IVR routing system using webhook subscriptions and the CallControl API. I integrated third-party platforms like Salesforce, RingCentral, Vertafore/AMS360, Epic, and EzLynx, and I replaced Delayed Jobs with Sidekiq + Redis for more reliable async processing.

I also strengthen teams and systems through mentoring and engineering practices—improving sprint delivery speed by 20% through code reviews and pair programming. I use monitoring tools like Bugsnag and Sentry and AWS infrastructure with Docker and Kubernetes to keep incidents visible and systems stable.
