════════════ ABOUT ME ════════════
Hi,
I am a Data Scientist, ML/NLP Engineer and Python Development Expert with 6+ years working across various domains. My core expertise lies in building end-to-end ML and NLP solutions - from data collection and processing, to model training, optimization and deployment via RESTful APIs.
I have extensive experience in:
- Training custom ML & NLP models from scratch (LLMs, Transformers, BERT, etc.)
- Developing AI agents, chatbots and assistants powered by GPT and Langchain
- Building recommendation engines, ranking engines, similarity engines
- Extracting insights from unstructured data using OCR, NER, text analytics
- Deploying scalable ML applications on cloud platforms (AWS, GCP, Azure)
- Data Analysis & Engineering: Extracting insights from large datasets, building ETL pipelines, data warehousing, and creating visualizations and dashboards
- Software Development: Proficient in Python, SQL, Java, and C++. Experience with Django, Flask, FastAPI for building scalable web applications and microservices
Having worked with both large enterprises and fast-paced startups, I bring a unique blend of technical depth and business acumen. I have successfully led data science teams and delivered impactful projects across ClimateTech, Biotech, Fintech, Media, Telecom, Legal and HR domains.
As an experienced freelancer, I pride myself on being a creative problem-solver who can rapidly prototype ideas and bring them to production. I ensure all deliverables are thoroughly tested, documented and deployed using industry best practices.
