About

I’m a software engineer specializing in backend and full-stack development with a strong focus on PHP, Laravel, and the Eloquent ORM ecosystem. I design and build production-grade web applications with clean architecture (MVC, Service-Repository pattern, Form Requests, and API Resources), optimized relational database schemas (MySQL, PostgreSQL), and efficient Eloquent queries leveraging eager loading, indexing, and transaction safety.

Alongside core backend engineering, I have hands-on experience implementing scalable asynchronous workflows with Laravel Queues and Redis, setting up CI/CD deployment pipelines (Jenkins, GitHub Actions), containerizing environments with Docker, and building modern user interfaces with React, Next.js, and TypeScript. I have also integrated real-time communication protocols and intelligent AI features into production systems, as well as mentored over 100 students in Object-Oriented Programming (OOP), algorithms, and software engineering.

Thesa.AI

Thesa.AI

Thesa AI is an intelligent, conversational search engine designed to help researchers, students, and professionals navigate the dense world of academic literature. By seamlessly integrating with leading academic databases, it allows users to ask complex questions in natural language and receive accurate, highly relevant answers backed by real scientific papers. Finding specific answers buried inside dozens of dense academic PDFs is time-consuming. Traditional keyword searches often fall short when you are looking for nuanced explanations or specific methodologies. Thesa AI solves this by turning the entire academic corpus of arXiv and Semantic Scholar into an interactive, conversational knowledge base.
