BACKEND SOFTWARE ENGINEER
I build backend systems that stay reliable beyond the happy path.
Backend Software Engineer focused on Python, FastAPI, distributed systems and applied AI — from API design and event-driven processing to deployment and reliability.

About
I'm Wesley Coutinho, a Backend Software Engineer and Computer Science student focused on distributed systems, reliability and applied AI.
I work primarily with Python, FastAPI, PostgreSQL, Redis and Docker, building backend services and integrating systems that need to process data reliably across different components.
My current professional work combines backend engineering, distributed processing and real-time computer vision.
Experience
I contribute to an intelligent traffic monitoring platform by building Python and FastAPI services, PostgreSQL data flows and Redis-based event processing. My work also covers reliability mechanisms, infrastructure and the integration of real-time computer vision pipelines using YOLO, OCR and RTSP.

I built an AI-powered conversational workflow for lead qualification, integrating the OpenAI API, n8n and external services to automate operational steps such as meeting scheduling.
