About Me
Currently working as a full stack engineer at VAll, shipping AI-driven products, designing backend systems, and managing infrastructure and deployments with around 3 years of experience building production systems.
I've worked across the stack while mentoring engineers and improving system reliability.
I also contribute to open source, including debugging real-world issues, submitting PRs, and helping maintainers ship reliable fixes.
I enjoy building scalable systems and breaking them down to understand how they fail and improve.

💼 Work Experience
- Building QuestCraftAI from scratch, an agentic AI platform serving 40+ NGOs. Designed and developed a 3-agent architecture using React, Node.js, PostgreSQL, pgvector, RAG, and OpenAI Agent SDK to automate internship and quest generation workflows, significantly reducing manual research effort.
- Designed and implemented agentic workflows using OpenAI Agent Builder, Gemini Gems, and Claude Code, orchestrated via internal MCP server.
- Created and deployed a custom MCP server on ECS, exposing 4 tools over VAllIndia's data, powering QuestCraftAI agents and an OpenAI-based chatbot that recommends NGO opportunities based on user resumes.
- Worked on end-to-end development of VAll India’s primary website, driving design and product discussions, using AI-first tools such as Lovable, Cursor and Claude Code for rapid development, and coordinating feature delivery and task delegation across the team.
- Owned and shipped the BYOQ collaboration module, enabling users to create quests, invite participants, and review team submissions through a responsive, validated interface built with React, Tailwind CSS, and shadcn/ui.
- Designed a distributed locking mechanism using S3 conditional writes to prevent duplicate job execution across multiple machines, eliminating race conditions where both servers would pick up the same job simultaneously.
- Implemented integration testing workflow from scratch using Testcontainers and Jest, covering 40+ APIs with automated runs on every PR via CI pipeline, catching environment-specific issues before production.
- Migrated data infrastructure from DynamoDB to PostgreSQL, leading the development of API v2 and successfully managing the full production migration with minimal downtime.
- Mentored 2 software engineers on code quality, scalable architecture, and engineering best practices.
- Prototyped an AI assistant for multilingual conversation support, instant doubt resolution, and mock interviews using Google TTS, Gemini, and STT systems, reducing projected manual support effort by 50%.
- Built an in-house Clash of Clans-style multiplayer strategy game, BOMB, using Unity and C#. Designed and implemented the in-game building placement and construction system, including grid-based interactions and gameplay logic. Fine-tuned a Google Gemini model on 50+ Clash of Clans base layouts to dynamically generate intelligent bot bases with varied defensive strategies.
- Designed and implemented CI/CD pipelines using GitHub Actions and blue-green deployment with Nginx, enabling zero-downtime releases.
- Built an in-house user onboarding and product guidance system using Shepherd.js, replacing an external platform and saving approximately $900 annually in subscription costs.
- Created Snapit AI, an AI-powered resume analysis platform using React, Tailwind CSS, NestJS, PostgreSQL, and Gemini API to deliver grammar correction, resume enhancement suggestions, and role-specific resume evaluation.
- Extended Snapit AI with interactive mock interview capabilities, generating questions and evaluating responses for feedback.
- Created a new task type called communication task. Used openAI whisper to transcribe audio to text and generate feedback using gemini. Help students improve their communication skills while answering technical questions.
- Integrated Razorpay payment gateway with SnapitAI, setting up multiple monthly plans and using webhooks for real-time payment processing and updates, generating around $200 in revenue.
- Owned and delivered multiple features, performed manual/smoke testing, and conducted final code reviews to ensure quality and reliability.
- Automated the mock interview process by enhancing the appointment booking system, migrating from Zoom to Google Meet using Google API, and reducing costs by 60%. Used cron and implemented auto-scheduling, meeting link generation, and automatic upload of recordings to Google Drive.
- Designed a progress report page to track student progress based on different parameters.
- Improved the performance of the landing page website from 55% to 85% by using Cloudinary CDN, removing unwanted code and NPM packages, and lazy loading images and pages.
- Built a coupon and UTM tracking system enabling attribution-based analytics.
- Re-designed the admin & student dashboard (31 Pages) using Tailwind CSS and Material UI.
- Delivered multiple end-to-end features, ensuring system reliability and production readiness.
