Hi, I'm Charchit Gangwar
Engineering Integrated and Automated Solutions for Modern, Scalable Applications.
About ME
Code & Dev
I have worked in a fast-paced startup environment at Workik, I engineered a multi-platform automation hub that integrated 6 developer tools like GitHub and Jira. I specialize in architecting end-to-end solutions, from designing secure, multi-tenant REST APIs with OAuth 2.0 to building complex workflow automation pipelines.
This hands-on experience extends to my personal projects, where I've built full-stack platforms from the ground up. My work includes architecting a university hub with real-time messaging using Ably and developing a RAG-based analysis tool with LangChain, containerized with Docker for seamless deployment. I leverage a modern tech stack including React, Node.js, and various databases to deliver robust applications.

Journey & Passion
Driven by a passion for solving complex puzzles, I leverage my strong academic foundation (9.2 CGPA) to build impactful, real-world solutions. I enjoy the entire development lifecycle, from deconstructing a user's problem to architecting an elegant, efficient system. This analytical approach is what fuels my success in competitive programming on platforms like LeetCode and Codeforces.
I'm a firm believer in the power of collaboration and actively contribute to open-source programs like Girl Script Summer of Code. Working within a team to resolve bugs, enhance UX, and achieve shared goals is incredibly rewarding. This blend of focused individual problem-solving and open-minded teamwork defines my approach to creating great software and continuously growing as a developer.
My Projects
Internship Experience
Software Development Intern
Workik
November 2024 - March 2025
I worked as an SDE Intern, where my responsibility was to develop a multi-platform automation hub that integrates multiple third-party apps like GitHub, GitLab, Bitbucket, Jira, etc., via OAuth, webhooks, and REST APIs. I created an event-driven architecture where a user's action (for example, raising a pull request) triggers a response, such as an auto-merge. I worked closely with a team on this project and later led them. I worked with Python, FastAPI, Node.js, Express.js, REST APIs, webhooks, system integrations, and workflow automation.
