● Designed, implemented, and maintained a ClickHouse data warehouse capable of processing 5+ TiB of data daily, integrating streaming and batch data from Apache Kafka, SFTP, Hadoop CDP, and web scraping pipelines. ● Delivered and maintained 300+ Apache NiFi ETL pipelines, covering data ingestion, data mart aggregation, and selfmonitoring processes. ● Contributed to a major cluster migration and resolved critical infrastructure issues, including ClickHouse node failures, replication mismatches, and data recovery from backups. ● Trained users and partner teams on ClickHouse and Apache NiFi, promoting best practices and enabling effective platform utilization.

● Enhanced and extended a model-agnostic Graph-of-Thought (GoT) and MCP-like framework, enabling non-reasoning LLMs to perform structured reasoning and generate functional software artifacts. ● Researched bioinformatics-focused AI tools and initiated the integration of autonomous research agents for life science studies, laying the groundwork for future research directions. ● Prototyped a lightweight NumPy-based LLaMA-style transformer, implementing encodings, forward pass, and quantization components for internal R&D. ● Managed three intern squads (15+ members) delivering projects in NLP classifers, RAG pipelines, LLM fne-tuning, and synthetic data orchestration.

● Mentored and guided 25+ students through Data Engineering courses and capstone projects, providing constructive feedback and personalized support to ensure a solid progress. ● Designed and delivered engaging lesson materials and case studies, making complex concepts accessible to students from diverse academic backgrounds. ● Coordinated with fellow mentors and management through regular meetings, aligning on student progress and continuously improving the learning experience.

● Provided input and recommendations to enhance learning materials, including presentations and case studies. ● Actively engaged with students by answering questions, assisting trainers, and facilitating group discussions. ● Offered feedback to students' capstone projects on advanced development.
