Services

Full-Stack Developer

I build scalable and user-focused web applications using modern technologies like React, Node.js, and PostgreSQL. From frontend interfaces to backend APIs, I focus on performance, clean architecture, and real-world usability.

Front-end Developer

I create responsive, interactive, and visually polished user interfaces using React and modern JavaScript. I prioritize user experience, accessibility, and clean component-based architecture.

Backend & API Development

I design and develop secure RESTful APIs, handle authentication, and manage databases using technologies like Node.js, Express, MongoDB, and PostgreSQL to power scalable applications.

AI Application Development

I build AI-powered features and tools using LLM integrations, LangChain, and custom workflows. My focus is on creating practical AI systems that improve debugging, automation, and user experience.

Projects

AI Log/Trace Debugger

Built a full-stack AI debugging dashboard that visualizes trace steps, tool calls, retrieval flow, latency, token usage, and errors across AI pipelines. It helps developers to quickly understand why an AI system responded a certain way and where failures or slowdowns occur, improving visibility into complex AI systems and enabling faster, more effective debugging.

Anime Tracker

Built a full-stack anime tracking application with authentication, protected routes, and user-specific data management. Each user has access to a personalized dashboard where they can manage their own anime collection through full CRUD functionality. Implemented RESTful APIs and JWT-based authentication to ensure secure data handling and responsive UI design.

Pokedex

Built a responsive frontend Pokedex application that integrates with a public API to fetch and display Pokémon data dynamically. It allows users to browse, search, and view detailed information through a clean and interactive interface. Implemented efficient state management and conditional rendering to handle asynchronous data smoothly and efficiently.

E-Commerces Project

This E-commerce product page provides a dynamic user experience with a lightbox gallery opening on a click, allowing customers to explore detailed visuals and seamlessly switch between images through small thumbnails; the responsive design a seamless and visually engaging shopping experience on different device screen sizes.

DevFinder

DevFinder is a GitHub Profile Viewer project that adeptly leverages the GitHub Users third-party API to fetch pertinent profile information. This project focus on delivering a sleek and user-friendly interface. The responsive design ensures an optimal layout, adapting seamlessly to various device screen sizes for an enhanced user experience.

API Advice Generator

I designed a user-friendly advice generator app using the Advice Slip API, offering interactive elements like hover states and enabling users to generate new advice by clicking the dice icon. The app's seamless adaptation to different device screen sizes, through responsive design, ensures an optimized viewing experience, enhancing the overall usability of the advice generator.
