Work Experience

Developer

EventHub

Present - Present

Built a full-stack platform that aggregates 100+ active opportunities daily from 5+ platforms into a single dashboard. Automated data extraction using Cheerio and the Google Gemini API to parse unstructured text and posters into clean titles, deadlines, summaries, and application links. Built a personalized skill-matching system that ranks listings based on user skills to surface the most relevant opportunities first. Improved database query response times by 5x by adding PostgreSQL B-Tree indexes on deadline and status columns. Configured node-cron to send automated daily email reminders in batches using Promise.allSettled(), alongside JWT authentication, a Kanban tracker, and Google Calendar sync.

Developer

DevConnect

Present - Present

Built a developer social platform allowing users to share build updates and notes tagged SHIPPED / BUG / LEARNING, with features to follow developers, upvote, and bookmark posts. Designed a normalized 6-model PostgreSQL schema using Prisma ORM, applying compound unique constraints to enforce data integrity and prevent duplicate likes or follows. Implemented cursor-based pagination for the main feed to fetch posts in batches of 15, keeping query response times under 100ms during infinite scrolling. Optimized frontend performance using route-level code splitting, keeping the initial critical bundle payload under 100kB for faster page loads. Secured API endpoints with JWT authentication, bcrypt password hashing, and rate limiting to protect auth and posting routes.

Developer

PrepAI

Present - Present

Built a platform where a user uploads their resume and picks a target role, and the app generates a personalized mock interview tailored to that role and background. Parsed the uploaded resume to pull out skills and experience, then combined that with the selected role to prompt the Google Gemini API for relevant interview questions. Generated targeted technical and behavioral interview questions alongside intention breakdowns and model answers, while evaluating a profile match score and flagging key skill gaps via Gemini. Structured the backend into separate modules for resume parsing, question generation, profile matching, and scoring, keeping the AI logic and application logic independently testable. Used Puppeteer to auto-generate a downloadable, ATS-style PDF report after each session, and stored session history in MongoDB behind JWT-authenticated routes so users can revisit past attempts.
