I build production AI, LLM, and data systems for enterprise, Web3, and high-scale platforms.
What I'm looking for
- Senior Machine Learning Engineer & Data Scientist with comprehensive experience delivering high-impact solutions across Enterprise SaaS, High-Scale Tech Platforms, and Web3.
- Expertise spans the full ML lifecycle: from Big Data Engineering (ETL, dbt, SQL) and Advanced Analytics to deploying Production-Grade AI Systems operating at scale.
- Strong technical foundation in Generative AI & LLMs (RAG, Agents), complemented by deep knowledge of Recommendation Systems, Search Algorithms, Classical Machine Learning and User Behavior Modeling.
- Proven ability to architect scalable MLOps and backend software solutions (Python, FastAPI, Golang, Docker), bridging the gap between research models and high-throughput APIs.
- Specialized in transforming massive unstructured datasets into actionable insights, driving product development through rigorous experimental design, A/B testing, and anomaly detection.
