Work

A journey through code, coffee, and countless commits. Here's where pixels meet purpose, and where I've spent my days building digital experiences that (hopefully) don't break when you need them most.

Technical Lead | Software Development Engineer III

  • Diagnosed and resolved a production outage from Postgres connection exhaustion on a shared primary crashing ECS tasks across services — rerouted 60–70% of read traffic to idle replicas overnight, restoring reads to p50 2–5 ms / p95 15–26 ms across major services, and extended the same replica pattern to Redis.
  • Led a cross-service member-unification migration consolidating 3 legacy member tables and 35+ downstream tables across 5 microservices into a single UUID-keyed accounts + members model — backfilling 5M+ records through a dual-write, feature-flag-gated phased cutover with zero downtime, ending in legacy archival.
  • Designed and shipped a Lambda-based OTP delivery system with isolated senders per channel (WhatsApp via WABA, SMS via gateway) and per environment — sustaining peak volumes of ~1M+ OTPs at a 0% system-side error rate and 97% end-to-end delivery.
  • Overhauled the platform authentication layer and unified registration for all frontends (free and paid) into a single source of truth — eliminating duplicate account creation and adding a Redis-backed rate-limiting layer to secure previously open endpoints.
  • Re-architected the free-member app flow to close a data-exposure risk in the registration API, splitting one endpoint into a frictionless public challenge-registration flow and an OTP-gated, rate-limited dashboard-login flow — enabling personalized journeys for repeat-challenge members.
  • Introduced GrowthBook as the org's unified feature-flag and experimentation platform, gating API rollouts (legacy→v2 cutovers, dual-write toggles, percentage-based read migration) at the NestJS controller level — now the platform standard.
  • Architected a Docker-based Lambda scaffold (Node.js and Python templates with local SQS / API Gateway emulation) adopted as the org-wide standard for all containerized serverless functions, versioned and deployed via ECR.
  • Built a production-grade NestJS service template and a centralized file service that removed duplicated S3 client code, and consolidated GitHub Actions into an org-level shared-workflows repo.
  • Rebuilt the source-attribution pipeline for free-member registration and reactivation flows in partnership with Marketing — restoring attribution across web, mobile-app, and Truecaller surfaces after RCA.
  • Established branch-based dev deployments via GitHub Actions, standardized AWS resource-naming conventions, and launched a new Link service in Golang before transitioning ownership.

Software Development Engineer II

  • Architected a BullMQ queue-driven export pipeline running Puppeteer across parallel Lambda workers, sustaining 500K+ creatives/day across 10+ organizations with real-time status, retry handling, and database updates on every completed job.
  • Led remediation of 800+ platform vulnerabilities to achieve SOC2 compliance, strengthening security posture across all services.
  • Migrated 65+ AWS Lambda functions (Node.js 14 → 18 → 20) with all dependent packages, and authored a custom GitHub Action for CI/CD deployment of Docker-based Lambdas with automatic IAM enforcement.
  • Containerized service deployments (AWS ECS/ECR) and built GitHub Actions CI/CD pipelines, cutting deployment time from 20 minutes to 5 minutes (~75% faster).
  • Engineered a Brand Safety system moderating GIFs and videos on Lambda — combining Google Vision for frame-by-frame content analysis with a real-time rules engine enforcing 30+ workspace-specific brand rules on every creative.
  • Automated canvas image export via Puppeteer-in-Lambda with optimistic credit computation and a stuck-project recovery mechanism, cutting export time by 2m 45s on benchmarked 5,000-creative projects.
  • Designed a scalable version-history system on S3 + Lambda using Brotli compression for 40% volume reduction, paired with S3 lifecycle policies that auto-expire outdated archives to cut long-term storage costs.
  • Built Rocketium's core video editor (comparable to Adobe After Effects), implementing precise timeline manipulation, keyframe movement, and layer snapping to support video production at scale.

Software Development Engineer I

  • Cut analytics processing from several minutes to 10–15 seconds by relocating compute-heavy front-end calculations to the backend, in partnership with backend engineers.
  • Developed a new animation engine on the Web Animations API (WAAPI), delivering stable 50+ FPS playback across browsers for all projects and improving render performance by 40%.
  • Established CI hygiene across 10+ repositories (Husky, Commitlint, PR templates, code review) and a unified logging system consolidating frontend and backend data, resolving 50+ critical on-call issues.
  • Engineered custom data-filter solutions for the Creative Analytics platform serving enterprise clients including Airtel, ADA, and Rappi, streamlining analysis across large creative datasets.
  • Instituted a fail-fast approach to front-end data handling, surfacing malformed or missing data at the point of failure and shortening issue-resolution cycles.
  • Extended the video editor's property and styling system to video elements and rebuilt interface components, including a modular, context-aware context-menu system.
