I'm a Senior Big Data and AI Engineer who builds production data platforms at petabyte scale and agentic AI systems that operate autonomously in production. Over the past nine years, I've worked across AWS, GCP, and Azure, delivering 50% faster pipelines, 40% cost reductions, and measurable automation of analytics workflows through LangGraph, Google ADK, and Databricks. On Upwork that translates into 21 completed contracts with near-perfect 5-star ratings and repeat enterprise clients — from quick, high-stakes database fixes to 100+ hour platform engagements. I take full ownership: architecture, cloud infrastructure, and delivery. WHAT CLIENTS HIRE ME FOR • Databases & DBA (deep specialty) — PostgreSQL, Citus, TimescaleDB, ClickHouse, and Trino: cluster design, replication and high availability, performance tuning, and migrations with zero data loss (RDS-to-Citus, 500GB+ PostgreSQL, ClickHouse shard/replication design). This is where my reviews are densest: - "His knowledge of ClickHouse Cluster is truly exceptional. He designed it exactly as needed." - "A game-changer — his analysis identified cost-saving opportunities and improved our solution architecture." (AWS database review) - "Super helpful even though it was new technology that's hard to find talent for." (pgvector on RDS Postgres) - "Did a fantastic job improving the database speed and migration." (500GB PostgreSQL migration) • Big-Data Platforms & Pipelines — Apache Spark, Trino, Apache Iceberg/Delta Lake, and Airflow + dbt on Kubernetes. I design petabyte-scale batch and streaming pipelines with the governance, lineage, observability, and SLOs production demands — typically 50% faster processing, 40% lower cost, and 99.9% uptime. • Production GenAI & Autonomous Agents — agentic systems on Google-ADK, LangChain, LangGraph, CrewAI, and MCP, plus RAG pipelines on Milvus, pgvector, and Pinecone. I ship them with real tracing and observability (LangFuse, Opik, MLflow) and guardrails — systems that run reliably, not demos. RECENT WORK • ClickHomes AI — a live real-estate analytics and lead-generation platform I architected end to end: a dual database (ClickHouse OLAP + PostgreSQL OLTP), a RESO-compliant ETL pipeline ingesting 9,500+ MLS listings with schema validation and lineage, a LangGraph ReAct AI search agent with streaming responses, multi-factor lead scoring, and Celery-powered email drip campaigns — deployed on Docker/Nginx and live in production. • TARA @ UXCam — an autonomous multi-agent analytics platform (Google-ADK + MCP) across 500+ mobile apps that cut analytics delivery time by 60% and manual effort by 75%, with RAG over 1M+ videos a month and full agent observability, governing 10TB+ of data per day on Databricks + Unity Catalog. HOW I WORK I design the architecture, stand up the cloud infrastructure, and deliver production-ready code — then make it observable, reliable, and cost-efficient. I communicate clearly and proactively across time zones, and I'm direct about trade-offs and timelines. TECH STACK Databases: PostgreSQL, Citus, TimescaleDB, ClickHouse, MySQL, MongoDB, Redis. Data: Apache Spark, Trino, Apache Iceberg, Delta Lake, Airflow, dbt, Kafka, Kinesis. AI/GenAI: Google-ADK, LangChain, LangGraph, CrewAI, AutoGen, MCP, RAG, Milvus, pgvector, Pinecone, Weaviate, MLflow, LangFuse, Opik. Cloud & DevOps: AWS, GCP, Azure, Kubernetes, Docker, Terraform, CI/CD, Prometheus, Grafana. Languages: Python, SQL, FastAPI, Next.js. Education: B.Tech in Computer Science. If you're building or scaling a data platform, fixing a database bottleneck, or putting an AI agent into production, send me a short brief — I'll reply with a concrete plan, a timeline, and the trade-offs that matter.

Over 8 years working on managing data projects for a top 100+ Co-operative Banks in Nepal. Areas of expertise include SQL, database design, implementation, development and administration (including Microsoft SQL Server Stack, Postgres Databases), visualization (including Tableau, Power-bi, Data Zen), OLAP development (Microsoft SSAS, Oracle Essbase), Ana-plan and more basic MI creation (Microsoft Access/Excel, VBA). Excited to get involved in projects involving any and all of the above, especially excited to take on projects involving database design from scratch and following through implementations.
