Description

Software Engineer & Data Specialist — Backend, Pipelines & Internal Tooling

I build data systems that actually work at scale — and I own them end to end.

Over 7 years at an AI-driven retail platform, I designed and maintained pipelines processing 2M+ products daily, built data quality monitoring tools used by both engineering and business teams. I defined standards, led technical training, and evolved systems as the product grew.

My core stack is Python, SQL, PostgreSQL, Django, and Docker.

I'm comfortable with the full lifecycle: ingestion, transformation, monitoring, alerting, and the internal tooling that keeps everything visible and actionable.

Beyond professional work, I'm currently building CuerpoSonoro — an interactive system that translates human movement into real-time sound using computer vision and audio synthesis. It's how I stay sharp on applied AI and real-time systems outside of client work.

I'm a good fit if you need:

- A data pipeline built or cleaned up

- Backend infrastructure with real ownership, not just ticket execution

- Someone who communicates clearly with both technical and non-technical stakeholders

July 2018 - October 2025 (7 years and 3 months)
Madrid, Spain
Over 7+ years at Centric Software (formerly StyleSage), I worked as a Software Engineer and Data Analyst on an AI-driven data platform for global retail and e-commerce.

I designed, built, and owned multiple data pipelines processing 2M+ products daily across international marketplaces, taking full end-to-end responsibility from architecture decisions to day-to-day maintenance.

I developed internal tooling for data quality monitoring, alerting, and KPI computation used by both engineering and business teams, and built decision-support systems that helped Customer Success teams prioritized data feeds based on quality signals and business impact.

I joined as part of a greenfield engineering team, which meant defining workflows, standards, and internal tooling from scratch, something I genuinely thrive in.

Over time, I evolved backend systems as requirements expanded from data ingestion into AI-assisted decision-making and advanced analytics.
Beyond the technical work, I led internal training sessions on deployments, CI/CD, and code quality, and consistently acted as a bridge between engineering and business stakeholders, translating complex technical constraints into clear, actionable solutions. I'm comfortable owning ambiguity, communicating across functions, and driving things forward without waiting to be told what to do.

Stack: Python, SQL, PostgreSQL, Exasol, Django, Docker, Git, CI/CD.
