Work Experience

Data Scientist

Tatras Data

Jan 2023 - Present

Built and evaluated a self-hosted Whisper Medium transcription pipeline using Python, Redis, Celery, and Docker to support a projected workload of 1,500 candidates and 750 hours of interview audio over 3 days. Performed infrastructure and cost analysis comparing self-hosted Whisper with Groq Whisper, identifying approximately 37% lower projected sprint cost while eliminating the need for 18 parallel Whisper servers. Migrated transcription inference to Groq Whisper Large v3 after latency evaluation, increasing processing throughput from ~0.6× real-time to 200×+ real-time. Built an LLM-driven candidate question-generation workflow using LangGraph to orchestrate candidate-data retrieval, resume parsing, question generation, and database updates. Designed category-specific interview question generation (icebreaker, resume-related, experience-related) using parsed candidate profiles. Integrated MongoDB for retrieval and persistence of candidate information and generated interview questions.

Associate Software Developer

Tatras Data

Jan 2023 - Feb 2023

Built and maintained production full-stack applications using React.js, Python, and FastAPI across frontend, backend APIs, data flow, and third-party integrations. Designed and implemented RESTful APIs handling data validation, business logic, and database interactions for production environments.
