Senior software engineer at Kozcomp building FastAPI product-matching pipelines with LLMs and a multi-tenant agribusiness SaaS.

Brazil
Message

At Kozcomp, I independently build a FastAPI platform that collects product data through APIs and web scraping, then normalizes titles, brands, categories, and attributes. I use LLMs to score matches, identify equivalent items, consolidate catalogs, and support price monitoring.

I also build a multi-tenant agribusiness SaaS integrated with a Flutter app and Google Maps. For the product platform, I implemented asynchronous Celery and Redis tasks with idempotency and scheduled monitoring.

At Fitpark, I built features and integrations for a parking-management platform using Python, Django, PostgreSQL, REST APIs, Docker, and AWS. I converted synchronous implementations into asynchronous Amazon SQS workflows that maintained operations during partial failures.

Earlier, I led Data Health, a PHP SaaS deployed in municipalities and healthcare facilities, serving more than 800K citizens. At Claire, I architected and developed a cloud eye-care platform and delivered lens calculation and recalculation features for SynergEyes VS and EUROPA Scleral.
