@javierojedarodrguez
Backend engineer building fintech APIs, microservices, and banking data connectors.
SpainWhat I'm looking for
I’m a Software Engineer specialized in Back-End development, focused on backend architecture and technological product development. I’ve built and maintained APIs and microservices for major fintech companies, with a strong emphasis on financial integrations.
From 2019 to Present, I’ve collaborated on Ojeda Fintech projects, contributing to open banking, financial aggregation, and high-performance backend development. I aim to keep delivering value in teams that prioritize scalable and reliable backend systems.
In my roles at Unnax / Powens (2020 - 2025), I developed and maintained banking connectors using web scraping and APIs to enable aggregation of data from hundreds of financial institutions. I also designed scalable backend services to normalize and expose financial information via REST APIs, improving reliability and traceability of bank scraping processes.
I strengthen production delivery through CI/CD and automation, using Docker, Kubernetes, and AWS. My technical background includes Python, Java, Kotlin, JavaScript, SQL, Django, FastAPI, Spring Boot, ExpressJs, React, and tools for scraping like Selenium and Playwright—plus observability-focused improvements like log optimization and error handling.
