Who I am

I started programming at 10, in an after-school academy, with Scratch. Today I build and run software in production. In between: competitive robotics, VEX mechanics, Unity games and Arduino electronics.

My path

  1. ScratchFirst steps in programming logic.
  2. Lego MindstormsEducational robotics.
  3. VEX RoboticsCompetition and mechanics.
  4. UnityGame development and C#.
  5. ArduinoElectronics, sensors and control.

Competition

🥇 LNRC — top placings in speedometer (Arduino PIDs)
🏅 RoboCAT — semifinals

That's why today I build and run end-to-end products: the technical curiosity goes back a long way.

Where I'm heading

I keep learning mostly by doing: I tinker with my homelab (Proxmox, Docker and Cloudflare Zero Trust) to try out what I later apply at work. My goal is to grow towards DevSecOps, building security into infrastructure and pipelines from the design stage, and I keep training in that direction.

Experience

  1. Optima Retail

    Vilassar de Mar

    1. Full Stack Developer & DevOps

      –

      After establishing myself as a developer on the in-house ERP, I took over its cloud infrastructure and CI/CD pipelines and was technical lead on client projects. I took part in technical decisions with the tech leads and was accountable for critical production incidents.

      • SSO & MFA: led the rollout of multi-tenant SSO with Active Directory federation over OpenID Connect and per-user TOTP 2FA, requested by a multinational luxury-sector company. Defined the solution with their technical team, demoed it to their IT management, and it became reusable for every other client.
      • Serverless invoice OCR pipeline deployed entirely with Terraform (Lambda, S3, SQS, Step Functions and Azure AI Document Intelligence). CI/CD with GitHub Actions authenticated to AWS via OIDC: no static keys and one IAM role per environment.
      • AI voice bot handling emergency incident calls, designed and built end to end: Amazon Connect, Lex, Polly, Kinesis and versioned Lambdas with CI/CD, integrated into the ERP backend.
      • Multi-tenant WhatsApp microservice on ECS with isolated dev and prod environments, API, admin panel, Sentry and continuous deployment with GitHub Actions.
      • Technical and cost assessment of AWS vs Azure, groundwork for migrating the ERP to AWS, and Dockerization of Laravel.
      • Contained a critical ARP spoofing incident and coordinated the network and Wi-Fi overhaul with an integrator and the ISPs.

    2. Full Stack Developer

      –

      Development and maintenance of the company's in-house ERP, from business logic to code quality and production support.

      • ERP features and business rules triggered by events and conditions.
      • Resolved critical production incidents, including full system outages, also outside working hours.
      • Pull request reviews as part of the mandatory QA process, plus GitHub Actions workflows validating syntax, dependencies and tests.
      • Kicked off, with the team, the move to hexagonal architecture and test coverage.
      • Onboarded new developers on processes, tools and architecture.

  2. Kriter Software

    Mataró

    1. Developer

      –

      Development and customization of ERP-CRM systems and e-commerce solutions.

      • Redesigned responsive web interfaces for Grupo Munreco's B2B systems.
      • OpenCart e-commerce customization, such as advanced filtering for product variants.
      • Docker and DevContainers to set up development and production environments.
      • Flask APIs exposing web application performance metrics.

  3. Espinaler

    Vilassar de Mar

    1. IT Staff

      –

      • Firewall, VPN and virtual PBX management.
      • Python and PowerShell scripts to streamline POS and ERP processes.
      • Features for the new e-commerce site (PHP, JS, CSS, HTML).
