What I'm looking for

I’m looking to build secure Ruby on Rails products in Agile teams—optimizing APIs, databases, and performance while delivering user-centric features with strong test coverage and code reviews.

I’m a Full Stack Developer with almost 2 years of experience building scalable, high-performance web applications using Ruby on Rails and JavaScript. I focus on clean architecture and API optimization to deliver user-centric solutions with measurable business impact.

I’ve delivered secure, data-driven systems serving 100K+ users and 1K+ vendors, improving performance by 25%. I implemented secure RBAC and data isolation for 1,000+ marketplace sellers, and reduced production bugs by 20% through enhanced test coverage and peer code reviews.

At Bestpeers Infosystem Pvt Ltd (Jun 2024–Present), I engineered full-stack modules, designed RESTful APIs, integrated third-party payment services, and optimized SQL queries and background jobs with Sidekiq to reduce API response times. I enjoy working in Agile sprints with designers and QA teams, and I’m excited to keep shipping reliable, scalable features—like Stripe-powered payment workflows and audit logging—end to end.
