About Me

I'm a pre-final year Computer Science student at Annasaheb Dange College of Engineering & Technology, Ashta (GPA 8.65). I have a strong foundation across the stack — from low-level DBMS and OS concepts to production-grade cloud deployments.

My work spans Kafka-based microservices, OCR document pipelines, full-stack web platforms, and LLM-powered applications. I'm comfortable diving into large codebases, designing system architecture, and shipping code that is both correct and maintainable.

When I'm not building, I'm solving DSA problems on LeetCode, contributing to open source, or writing technical blog posts about ML concepts.

🎯 Currently seeking internship / full-time backend roles and freelance projects in web development, APIs, and AI integration.

Web Development

Full-stack applications with React, Node.js & Spring Boot. From MVPs to production platforms with auth, payments, and REST APIs.

Backend Systems & APIs

Scalable REST APIs, microservices, event-driven systems with Kafka, and database design with indexing and query optimization.

AI Integration & Automation

Integrate LLMs via LangChain, build agentic workflows, automate repetitive tasks, and add intelligent features to existing systems.

Legacy & Desktop Software

Desktop applications, ERP-style software, chit fund management, and data monitoring tools built with Java, C#, and SQL Server.

Mobile App Development

Cross-platform mobile apps with responsive UIs, backend API integration, push notifications, and real-time features.
