Full Stack Developer · OmniLithTech (Remote)  |  Next.js, Webhooks, SMTP  |  Apr 2026 – Jun 2026

• Automated lead capture through a secured webhook integrated with MacroDroid, using a round-robin assignment algorithm to eliminate ~5 minutes of manual data entry per call.
• Modernized appointment scheduling by integrating the Google Calendar API with SMTP for instant meeting-link generation and auto-dispatched invites, cutting coordination overhead.
• Built a fault-tolerant CSV/XLSX import pipeline with fuzzy column mapping and algorithmic client allocation, instantly processing and assigning up to 500 records per upload.

Backend Developer Intern · Prysm Labs (Remote)  |  NestJS, Prisma, FCM  |  Feb 2026 – Apr 2026

• Architected a real-time, dual-layer notification engine using Socket.IO for room-based chat and Firebase Cloud Messaging, guaranteeing delivery for alerts and messages.
• Built a privacy-preserving virtual telephony integration with Exotel, handling asynchronous webhook callbacks for call-state tracking and real-time event logging.
• Implemented an OTP system with master overrides and real-time SOS emergency triggers for the TMS platform.

Open Source Contributor · Accord Project  |  TypeScript, GitHub Actions  |  Dec 2025 – Feb 2026

• 35+ merged PRs across 12+ repositories.
• Configured E2E testing infrastructure with Playwright, improving CI stability, and optimized existing CI workflows.
• Migrated template sharing from query parameters to URL hash fragments, contributing 1,500+ lines of code.

SkillBridge: AI-Powered Mock Interview Platform  |  Next.js · PostgreSQL · Redis · Vapi · Gemini · QStash  |  GitHub

• Production-deployed, real-time voice interview SaaS with relationally-sound database models, Firebase session-based auth, and a layered service architecture that reduced inter-layer coupling.
• Moved synchronous LLM calls to async background jobs via message queues with exponential backoff, and added a Redis cache-aside layer (15-min TTL) to cut dashboard database read load.
• Designed an observability stack with a sliding-window rate limiter (4 req/hr/IP) plus Pino and Sentry for structured logging and error tracking.

Vessel: Remote Browser Isolation System  |  Node.js · Docker · WebSockets · CDP · Puppeteer Core  |  GitHub

• Built a streaming pipeline via a custom WebSocket reverse proxy with on-demand port allocation, pulling headless Chromium frames over CDP at 30 FPS with zero cross-session data leakage.
• Devised a TTL-based graceful reconnection mechanism decoupling sockets from container lifecycles, enabling session recovery and automated 2-minute garbage collection.
• Enforced strict Linux cgroup resource limits via the Docker API for stability, eliminating the noisy-neighbor problem.

ForecastIQ: Predictive Forecasting Tool (Team Project)  |  Python · Flask · CrewAI · Gemini · NewsAPI  |  GitHub

• Orchestrated a collaborative 3-agent AI debate mechanism to investigate and explain the root causes of forecasting anomalies.

_{CS Fundamentals: OOP · Database Management Systems · Operating Systems · Computer Networks}
