Work Experience

Software Solution Engineer – Frontend & Integrations

MoEngage

Dec 2023 - Present Bangalore, India
  • Owned end-to-end React.js dashboard builds for enterprise clients (JPMorgan Chase, Citi, Tata) — drove 40% gain in data-insights accuracy via UI/UX redesigns and component refactoring.
  • Achieved 30% load-time reduction via code-splitting, React.lazy, and memoization; established performance budgets adopted team-wide.
  • Shipped 50+ production REST APIs for campaign analytics in Node.js/Express.js, cutting end-to-end latency by 35% via query optimisation and response caching.
  • Built real-time internal monitoring dashboards with live alerting, reducing backend incident MTTR by 40%.
  • Maintained a 1M+ entry PostgreSQL store — composite indexes and N+1 rewrites cut p99 query time by 50%.
  • Led cross-functional integrations with Salesforce and Segment; owned SDK config, webhook validation, and client onboarding docs.

Projects

Easibill

React.jsNext.jsNode.jsPostgreSQLRedisAWS EC2DockerGitHub Actions
  • Architected a modular React/Next.js frontend with drag-and-drop email editor and multi-step campaign builder — zero third-party form dependencies, fully keyboard-accessible.
  • Integrated Resend (transactional email) and Gupshup (WhatsApp Business API) for automated multi-channel refill reminders targeting 120+ pharmacies across tier-2/3 cities.
  • Migrated data layer from MongoDB → PostgreSQL with Drizzle ORM; schema redesign and connection pooling delivered 2× throughput under concurrent production load.
  • Deployed on AWS EC2 with Docker + GitHub Actions CI/CD; implemented Redis caching, per-tenant rate-limiting, and structured JSON observability logging.

Web Analytics SDK

JavaScriptCloudflare WorkersNode.js
  • Built a <5 KB zero-dependency browser SDK capturing sessions, clicks, rage-clicks, and custom events — drop-in <script> tag, no build step required.
  • Sub-10ms event processing latency routing all events through Cloudflare Workers at the edge, eliminating origin cold-start delays entirely.
  • Adaptive batching with exponential back-off and local queue persistence cut origin-server load by ~60% under burst traffic without data loss.

Trackmail

PythonPlaywrightNode.jsMongoDBAWS SESGitHub ActionsClaude API
  • Python/Playwright scraper extracts recruiter and job-poster contacts from LinkedIn, enriching each lead (role, company, seniority) into a structured MongoDB targeting pipeline.
  • Node.js bulk-send engine via AWS SES with full SPF/DKIM/DMARC auth and a 6-week inbox warmup curve — achieved consistent inbox placement on a cold domain from scratch.
  • Jittered send intervals, bounce suppression, and one-click unsubscribe tracking cut spam rate from ~80% (Gmail) to <5%; fully orchestrated via GitHub Actions daily cron.
  • Integrated Claude API to generate hyper-personalised email copy per lead — pulls role, company, and activity context to produce unique subject lines and body variants, lifting reply rate vs. templated sends.
