What I'm looking for

I’m looking to build production backend systems for AI/IoT products—designing scalable REST APIs, integrating ML outputs, and deploying on cloud with CI/CD. I enjoy cross-functional work and shipping reliable, automation-driven solutions.

I’m a backend & software engineer with 2+ years of experience building backend systems, AI-powered applications, and IoT solutions. I focus on production-ready REST APIs, ML integration, and scalable cloud architectures using Node.js and Python.

At UIB, I designed an AI-based solution to extract structured data from unstructured financial documents, building end-to-end machine learning pipelines and delivering the results through Node.js/Express REST APIs. At Capgemini Engineering on the BMW project, I supported high-reliability embedded validation by analyzing CAN bus signals and logs, managing defects in Jira, and collaborating cross-functionally to improve system stability.

In parallel, I’ve delivered freelance SaaS and IoT backend systems—multi-tenant apps with JWT and RBAC, real-time sensor data APIs, ETL pipelines, and cloud deployment using Docker and AWS/Azure with CI/CD and microservices. I bring a practical mindset from embedded C/C++ work and a clear commitment to building systems that are accurate, reliable, and maintainable.
