At Dreem, I built two production MCP servers that expose case data and a CRM to Claude. I also built a durable PostgreSQL job queue with leases and backoff, and ETL that syncs business systems into one PostgreSQL database.
I measure LLM quality and cost: gpt-5-mini reached 92% recall versus 65% for gpt-5.1, so the cheaper model won. I also routed only oversized petitions to a long-context tier and removed 167 duplicate LLM calls in 15 hours.
At HiQo Solutions, Inc., I worked on FastAPI, Flask, and GraphQL backends that were 40% faster, and YOLOv8 inference on AWS Lambda that was 40% faster. A ChatGPT API code-commenting tool increased scenario coverage by 67% and accuracy by 25%.
At Microsoft, I worked on Dynamics 365 tax localisation for VAT in Europe, Russia, and Brazil, reducing filing errors by 15%. Earlier, I worked as a Risk Analyst at AK Bars Bank and a part-time Software Developer at CESI.
