About

I’m Roney Silva, a Full Stack Software Engineer from Brazil with 2 years of experience building end-to-end features using TypeScript, Node.js, React, and AWS. I focus on delivering complete modules—from database and API behavior to polished user interfaces—while also digging into tricky production problems and performance bottlenecks.

In my recent work at BuildMate, I’ve helped stabilize critical systems, including resolving incidents tied to WebSocket reconnection behavior, and I’ve achieved measurable results like cutting AWS costs by 48% and eliminating frequent backend deadlocks. I also enjoy building UI experiences that stay responsive (such as PDF generation using Web Workers) and delivering data-heavy dashboards that stay reliable at scale.

Work experience

Software Engineer (Full Stack) — Intern → Junior → Mid-Level · BuildMateAug 2024 – Present · 2 yrs 4 mos

Worked across the stack with TypeScript, Node.js, React, Express, Prisma, PostgreSQL, and AWS services (App Runner, Amplify, EC2, RDS, Route 53, CloudWatch, S3). Contained a production incident that caused the Node.js API to be unavailable by isolating and fixing a reconnection-loop issue affecting WebSocket notifications. Cut AWS costs by 48% and eliminated all 500 errors and TypeScript backend instability related to an incompatibility between App Runner load balancing and WebSocket protocol. Reduced execution time by 98% by removing weekly deadlocks in a Node.js/PostgreSQL routine and replacing loop-based updates with a parameterized Prisma raw query. Improved UX by eliminating UI freezing during PDF generation using React refactoring with Web Workers. Delivered a React/TypeScript/SQL dashboards & metrics module for procurement workflows and built bulk operations with an async processing queue and S3 image storage.
