Work Experience

Full Stack Web Developer (MEAN Stack)

Veranda RACE

Feb 2026 - Present

Diagnosed and fixed 6 critical data-correctness bugs in a leaderboard system and re-architected the computation pipeline with parallelisation and two-layer caching — cutting response times from 23–37s to under 500ms. Built a Jodo EMI payment webhook system that reconciles payments to orders and extends LMS subscription access, backed by a cron-driven Testpress batch-sync and validation pipeline. Rebuilt and hardened a 4-year-old legacy backend for the BVM Global Schools platform into a dedicated, validated Node.js/Express service — adding structured request validation and centralized error handling to improve server stability and failure resilience, along with CORS policy configuration, Helmet security headers, CSRF protection, and input sanitization against injection attacks. Built internal dashboards for sales/admissions budget tracking and AWS S3-based file management (uploads, folder parsing, shareable links). Used the Zoho Books API (OAuth token flow) to pull and update invoice records for IT asset reconciliation, cross-referencing vendor rental invoices against internal employee-asset records. Delivered new frontend pages and features on the platform, including a route-aware sticky ad banner with dismissal tracking and a reappear timer. Implemented authentication end-to-end — Mongoose schema validation, Argon2 password hashing, JWT/OAuth session flows, route guards and interceptors.

MEAN Stack Developer Intern

Veranda RACE

Sep 2025 - Jan 2026

Built and maintained Angular frontend modules and Node.js/Express backend APIs across production codebases, gaining end-to-end full-stack exposure. Wrote MongoDB queries, Mongoose schemas, and Express controllers for data-driven features; tested and validated APIs with Postman. Took part in code reviews, sprint planning, and Agile ceremonies alongside senior engineers, quickly picking up team coding standards and deployment workflows. Used AI-assisted debugging tools to trace root causes and implement fixes faster.
