SS Shaheryar Shaikh Backend-first product engineer

Travel Tech @ Vernost

Backend-first, product-aware, scaling for real traffic

Backend systems that stay fast when the product gets busy.

I build scalable products with Node.js, Angular, React, NestJS, MongoDB, AWS, microservices, and APIs that are made for real-world traffic.

I work on bookings, integrations, lending, analytics, and automation with a focus on speed, scale, and user flows that stay clean.

About

Code that solves product problems, not just tickets

I care about performance, maintainability, and user flow equally. Good systems should run well and stay easy to build on.

At Vernost, I build travel products where performance, reliability, and booking flow quality matter every day. I work across Node.js, AngularJS, React, NestJS, MongoDB, and AWS, with a strong focus on maintainable systems.

Before that, I worked on lending, analytics, automation, OCR, and internal tools at iorta and TCS, which sharpened both my product sense and engineering depth.

What I bring to a team

  • Backend systems built for scale with Node.js, Express.js, and NestJS
  • Frontend execution with AngularJS, React, and React Native when needed
  • Hands-on delivery with MongoDB, Redis, AWS Lambda, and CloudFormation
  • Microservices, caching, and supplier integrations that reduce friction
  • REST API design, auth flows, validation, and performance tuning with product impact

Experience

Where I have built, shipped, and improved things

My best work usually sits between system design, delivery speed, and product impact.
