I help companies move, process, and use their data on AWS — from event-driven ETL pipelines to RAG-powered AI applications. For the past 4+ years I've built exactly that at the U.S. Securities and Exchange Commission, handling high-volume financial data. THREE THINGS I DO 1. DATA ENGINEERING — Design and build ETL/ELT pipelines with Apache Airflow, PySpark, AWS Glue, and Redshift/Iceberg. Batch or event-driven, greenfield builds or rescuing pipelines that keep breaking. 2. CLOUD ARCHITECTURE (AWS) — Architect serverless and containerized systems with Lambda, ECS, S3, and DataSync, all as infrastructure-as-code (AWS CDK, CloudFormation). Migrate legacy on-prem workloads to AWS with CI/CD from day one. 3. AI & LLM APPLICATIONS — Build RAG systems with vector search (Qdrant), LLM-powered document analysis, and AI features shipped inside real products (Python, Next.js, OpenAI API). RESULTS I'VE DELIVERED • Cut data availability from ~1 hour to minutes with event-driven AWS pipelines (SEC) • Reduced deployment cycles from 9 weeks to 4 by automating CI/CD for AWS Glue ETL jobs (SEC) • Built a private RAG document-Q&A system over internal docs — semantic search with no data leaving the org • Saved 75 analyst-hours per week by automating manual data workflows (Comcast) TECH STACK • Languages: Python, SQL, TypeScript/JavaScript, R, Golang • Data Engineering: Apache Airflow, PySpark, AWS Glue, Pandas, NumPy, Alteryx • AWS Cloud: S3, Lambda, ECS, EC2, Athena, Redshift, Iceberg, DataSync, RDS/Aurora, DynamoDB, SNS, CDK, CloudFormation, SAM, LocalStack, CloudWatch • AI / LLM: LLM API(Anthropic, Gemini, OpenAI), Vector DB, RAG pipelines, AI-assisted development with Claude Code & Cursor • Databases: PostgreSQL, MySQL, Redshift, MongoDB, Neo4j, DynamoDB, Supabase • Web & APIs: React, Next.js, Node.js, FastAPI, Flask, Prisma • DevOps: Docker, GitHub Actions, Bamboo, Splunk, Jupyter CERTIFICATIONS • AWS Certified Solutions Architect • AWS Certified Data Engineer HOW I WORK Clear communication, tested code, and documentation your team can actually maintain. Everything I build is infrastructure-as-code — reproducible in your environment, no black boxes, no key-person risk. Tell me about your data stack, your cloud setup, or the AI feature you want to ship — I'll reply with a concrete plan for how I'd build it.
