I'm Jahangir, a Software Engineer from Bangladesh.
Here's a quick intro about me and what I love to do
My tech journey
My programming journey began with a curiosity about how technology shapes our world. I found myself drawn to the intersection of AI and practical software applications, leading me to explore machine learning and full-stack development simultaneously.
Diving into AI and ML
As my skills evolved, I found my passion at the intersection of AI and software engineering. I've built everything from RAG-based LLM models for financial insights to time series forecasting algorithms using GRPO and Transformers for my thesis. The ability to create intelligent systems that solve real-world problems continually fascinates me.
Hackathons and Projects
I thrive in the fast-paced environment of hackathons, where innovation meets tight deadlines. Winning the BUET CSE Fest 2024 Hackathon with EasyTrip and becoming a NASA Space Apps Dhaka champion are achievements I'm particularly proud of. These experiences have shaped my approach to problem-solving and teamwork.
These Days
Currently, I'm working as a Software Engineer at Maxint, where I build RAG-based LLM models and develop regression-based auto transaction categorization systems. I'm also completing my B.Sc. in Computer Science and Engineering at Jagannath University, expecting to graduate in April 2025.
When I'm not coding, you might find me playing chess, writing poetry, or exploring new technologies. I'm passionate about knowledge sharing and regularly contribute to open-source projects. My goal is to continue pushing the boundaries of what's possible with AI and software engineering.
