My Work Experience

Where I've interned and worked during my career.

Aervio | Jun 2019 - Apr 2025

CTO & Co-founder

After taking over full technical leadership, my focus shifted from building to optimizing and scaling: making data-driven product decisions, improving operations teams' experience, and applying AI to the product's core. - Owned product strategy and roadmap: prioritized features based on user feedback and platform analytics, maintained direct contact with power users to identify pain points and drive improvements - Designed KPI systems to measure and optimize platform adoption (from ~37% to over 70% online operations vs. offline processes) - Platform enabled average response time of ~25 minutes for travel requests — vs. the industry standard SLA of 3 hours — by streamlining provider search and proposal delivery within a single interface - Integrated Natural Language Processing (NLP) for automated travel request handling from email; later replaced with OpenAI API solution, significantly improving accuracy - Leveraged Segment and Amplitude for product analytics, user behavior tracking, and continuous product optimization - Platform reached ~€1M/month in managed travel bookings with a team of ~10 agents Tech: C#, ASP.NET, .NET Core, SQL Server, AngularJS, Python, OpenAI API, Azure, Segment, Amplitude

MundiAudit, S.L. | Feb 2013 - Apr 2016

Analyst Programmer & Scrum Master

Hired as part of a small team to build iAudit from scratch — a comprehensive audit management platform for the Spanish public sector.
