👋 Hi there! I'm Javi

🚀 About Me

Lead Blockchain and SSI Engineer focused on building scalable, resilient, and future‑ready systems. My work bridges cutting‑edge technologies across Blockchain, Agentic AI, and Digital Identity, always with a strong emphasis on maintainability, performance, and engineering excellence.

As a Tech Lead, I have led projects for both fast‑moving startups and large enterprises, designing solutions that balance innovation with operational robustness. I specialize in:

  • Architecting distributed systems with Blockchain, EVM, and Digital Identity (SSI) technologies.
  • Building reliable ETL and data‑driven platforms, including real‑time analytics pipelines.
  • Developing high‑quality backend services using Node.js and Python.
  • Designing cloud‑native infrastructures across Azure, GCP, and containerized environments with Docker.
  • Driving engineering strategies that prioritize scalability, simplicity, and long‑term maintainability.

I am known for being a Problem Solver who unblocks teams, clarifies complexity, and delivers solutions that simply work.


🧩 Highlight Projects

  • Real‑time Analytics Platform — Designed and implemented a high‑throughput pipeline to compute location‑based reward models.
  • Proof‑of‑Faith System for Legal Documentation — Built a verifiable and tamper‑resistant mechanism leveraging blockchain cryptography.
  • Operational Cost Optimization for Blockchain Networks — Reduced resource consumption and improved reliability across distributed components.
  • Functional APIs for EVM & SSI — Delivered API ecosystems for identity and smart‑contract‑based workflows.
  • Digital Identity Implementation — Led the adoption and rollout of a secure, standards‑aligned identity system.
