What I'm looking for

I’m looking for a role where I can build production-grade AI systems—especially RAG pipelines, healthcare/fintech applications, and hybrid models—while collaborating in an English-speaking remote team. I’m open to remote or relocation and value practical engineering impact.

I’m a computer science graduate with a GPA of 3.82/4.00 and an aspiring AI Engineer mindset—focused on building production-grade AI systems in healthcare, fintech, and computer vision. I design end-to-end RAG pipelines and hybrid deep learning architectures, combining Python, LangChain, FastAPI, PyTorch, and Docker to ship real solutions that work in constrained environments.

In projects like MediFlow, I built a local healthcare AI platform with document ingestion, clinical extraction (including ICD-10 coding), RAG chat with source tracking, compliance checks against SOPs, and audit history. I also created GOTCHA, a real-time fraud detection platform using a hybrid Random Forest + Isolation Forest + GPT-4o approach, including privacy-first synthetic data generation; and I’ve supported software development in a hospital setting by building Java-based desktop/Android systems connected to MySQL and supporting infection surveillance workflows.
