Hi, I'm Ashay Kargaonkar

I'm a Software Engineer with 4+ years of experience building secure, scalable web applications using JavaScript and .NET technologies. I specialize in backend development with C#, ASP.NET Core, and Entity Framework, and frontend development with React, Next.js, and TypeScript. I leverage tools like Postman for API testing, Veracode for security scanning, and Harness for CI/CD automation. For rapid frontend development, I use Windsurf AI to streamline my workflow and enhance productivity.

My expertise spans RESTful API development, SQL/NoSQL database integration, and implementing CI/CD pipelines for seamless deployments. I have extensive experience with cloud-native development, leveraging AWS services including Lambda, App Runner, Cognito, S3, and EC2 to build scalable and resilient applications. Notable projects include ThinkMoves—a web platform built with React and .NET for digitizing chess scoresheets—and AshayTalks, a personal chatbot powered by a custom C# API and JSON data backend. I've successfully led full project lifecycles, modernized legacy systems, and contributed to production-grade applications serving over 1 million daily users. With a Master's in Computer Science and hands-on experience in both backend systems and frontend development, I focus on building responsive interfaces and high-performance systems that solve real-world problems. I'm open to relocation and passionate about creating impactful full-stack solutions that deliver exceptional user experiences.

Overview

ThinkMoves is an AI-powered platform that converts handwritten chess scoresheets into accurate, digital PGNs, making post-game analysis fast, reliable, and shareable. It is built using Azure’s OCR and document classification services to automate the reading and interpretation of structured scoresheets.

Currently supporting the ThinkMoves scoresheet format, the platform identifies key regions like player names, game metadata, and move sequences. It validates extracted moves using chess rules, reconstructing the full game while allowing users to review and edit where needed.

ThinkMoves reduces the effort for players, coaches, and tournament organizers by eliminating manual data entry and enabling digital access to game records. It is designed to expand to support more sheet formats, making it a scalable tool for the broader chess community.

Overview

AshayTalks is a personal AI chatbot I created to give recruiters and collaborators a faster, more intuitive way to understand my background—without digging through resumes or LinkedIn profiles. Built with GPT-4o-mini, it provides clear, reliable answers about my work experience, technical skills, and projects.

I developed AshayTalks to save time during hiring conversations and to offer a more interactive way to showcase who I am professionally. It’s continuously evolving as I add new projects, skills, and experiences, making it a living reflection of my growth as a Software Engineer and Data Scientist.
