What I'm looking for

I'm open to remote contracts focused on AI systems, data pipelines, or backend engineering, where I can build practical automation and scalable integrations.

I work across the full stack of modern AI and data infrastructure: ETL pipelines on Databricks and Spark, backend APIs in ASP.NET Core, and AI systems using LangChain, OpenAI, and RAG architectures.

From T-SQL ETL pipelines and ASP.NET Core APIs to financial data pipelines on Databricks, AI integrations with OpenAI and LangChain, automation systems using Selenium and Playwright, and cloud infrastructure on AWS Lambda, S3, and ElasticBeanstalk.

Some things I've built:

▸ Enterprise financial data pipelines reconciling 7–10M records per table into Delta Lake — reduced pipeline runtime from 27 to 10 minutes

▸ Ophthalmic imaging platform integrating HL7 v2 and FHIR with external EHR systems — built DICOM handling for clinical image capture, metadata extraction, and study association across AWS Lambda and S3

▸ Healthcare Practice Management System handling end-to-end billing, claims, and payment workflows across 4 clients — 15,000–20,000 claims processed

▸ 3-agent LLM pipeline for Generative Engine Optimization — measuring and improving business visibility across AI assistant responses

▸ RAG pipelines over large public codebases using ChromaDB and OpenAI embeddings — reduced scene discovery from hours to seconds

▸ Multimodal Instagram analyzer combining OpenAI Vision, Whisper, and GPT-4 across 10–15 managed accounts

▸ manim-Astronomy — open-source Python library for astronomical animations, published on PyPI

Also run AgenticStack Labs, building AI systems for professional service firms. 100% Job Success Score on Upwork across 5 years of freelance delivery.

Open to remote contracts — AI systems, data pipelines, or backend.
