My work focuses on backend engineering, distributed data pipelines, and modernizing systems that need to perform reliably under real production load. I’ve spent my career designing backend architectures that stay fast, stable, and cost‑efficient as they grow. Whether it’s a Java microservice that needs to scale, a Python backend that needs to be production‑ready, or a data pipeline that has to process millions of records without breaking, this is the work I do every day. 𝗛𝗼𝘄 𝗜 𝗛𝗲𝗹𝗽 𝗧𝗲𝗮𝗺𝘀: 𝗝𝗮𝘃𝗮 𝗘𝗻𝘁𝗲𝗿𝗽𝗿𝗶𝘀𝗲 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 𝗮𝗻𝗱 𝗥𝗘𝗦𝗧 𝗔𝗣𝗜𝘀: If your backend is slow, fragile, or stuck inside a monolith, I fix that. I work with Spring Boot, Spring MVC, Spring Security, JWT authentication, GraphQL, and microservices. I modernize legacy Java codebases, break apart monoliths, and build APIs that stay reliable when traffic spikes. 𝗣𝘆𝘁𝗵𝗼𝗻 𝗕𝗮𝗰𝗸𝗲𝗻𝗱 𝗮𝗻𝗱 𝗙𝗮𝘀𝘁𝗔𝗣𝗜 𝗦𝗲𝗿𝘃𝗶𝗰𝗲𝘀: I build Python services using FastAPI, SQLAlchemy, asyncio, and Pydantic.

𝗗𝗮𝘁𝗮 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝗮𝗻𝗱 𝗘𝗧𝗟 𝗣𝗶𝗽𝗲𝗹𝗶𝗻𝗲𝘀: If your pipelines are brittle, slow, or producing outdated data, I rebuild them. I work with Apache Beam, Spark, Airflow, Kafka, dbt, Snowflake, and BigQuery. At Ford, I replaced a six‑hour Hadoop batch job with a Dataflow streaming pipeline that finished in under ten minutes. 𝗗𝗮𝘁𝗮𝗯𝗮𝘀𝗲 𝗗𝗲𝘀𝗶𝗴𝗻 𝗮𝗻𝗱 𝗣𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲 𝗢𝗽𝘁𝗶𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻: I tune SQL queries, redesign schemas, and optimize databases at scale. I’ve worked with PostgreSQL, SQL Server, MongoDB, MySQL, Redshift, Snowflake, and BigQuery. 𝗟𝗲𝗴𝗮𝗰𝘆 𝗦𝘆𝘀𝘁𝗲𝗺 𝗠𝗼𝗱𝗲𝗿𝗻𝗶𝘇𝗮𝘁𝗶𝗼𝗻: I migrate old systems without disrupting what already works. I’ve moved slow stored procedures into Spark and Hive, improving execution time across distributed file systems. 𝗔𝗣𝗜 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀: I build reliable integrations with third‑party APIs, handling authentication, pagination, rate limits, retries, and logging.
