I am a Software Engineer dedicated to building scalable, high-performance backend systems and production machine learning applications.
With over 4 years of hands-on experience, I specialize in architecting distributed microservices using Go (Golang) and Python. My work spans designing mission-critical enterprise platforms—such as the Agricultural Lab Management and Reporting System (ALMRS) under the Ministry of Agriculture—to developing AI-integrated solutions with LangChain, Docker, and PostgreSQL.
On the research front, my work in transformer-based topic modeling has been published by Springer Nature ('Proceedings of the 3rd International Conference on Big Data, IoT and Machine Learning'). I was also honored to be selected as a top finalist in the Harvard-founded Aspire Leaders Program from over 54,000 global applicants.
Whether collaborating on production engineering roles, enterprise architecture consulting, or academic research, I bring polyglot programming rigor, systems thinking, and end-to-end execution to complex technical challenges.
From undergraduate honors and selective Harvard leadership training to active graduate research in Computer Science.
Enrolled in the Master of Science in Computer Science (MScCS) program at AIUB (Admitted: 03-Jun-2026). Currently undertaking advanced graduate coursework across machine learning, neural networks, blockchain cryptography, and modern computing advancements.
Selected as a top finalist in a prestigious global academic and leadership development program founded by Harvard University faculty. Completed HarvardX coursework, leadership simulations, and capstone social impact project with mentorship from Harvard faculty.
I am open to discussions regarding AI Systems research collaborations, funded PhD opportunities (Fall 2026 / 2027), and specialized machine learning engineering initiatives.
