About me
Senior full-stack and platform engineer, remote from Spain. Built and operated production systems for Alaska Airlines (30K+ employees), Kitco.com (24M+ users) and ZeroHedge (40.8M-document migration). I ship with tests, verification steps and explicit scope. Available now for remote contracts.
Platform & Infrastructure Engineering (Kubernetes, GCP)
Expertise in Kubernetes (GKE, Helm, HPA, Gateway API, Workload Identity) and GCP services (Cloud SQL, Cloud Tasks, Storage, Gemini API). End-to-end ownership of production platforms including architecture, delivery, operations and incident response across multi-cluster, multi-region environments with blue/green deployments and autoscaling to 100+ nodes.
Full-Stack Development (TypeScript, React/Next.js, Node.js, PHP/Drupal)
Deep proficiency in TypeScript, JavaScript, React, Next.js, Node.js, PHP and Drupal 10/11 for building production-grade web applications. Experience spans headless CMS architectures, GraphQL APIs, REST APIs, and frontend frameworks including Astro, Vue, React Native and Tailwind CSS.
AI Engineering & LLM Integration
Hands-on experience with multi-provider AI integration (Claude, OpenAI, Gemini, OpenRouter, Ollama), RAG pipelines (hybrid lexical and HNSW retrieval, Voyage/Cohere reranking, Langfuse), MCP servers, agent orchestration and skills systems, AI moderation in production, streaming STT, OCR and LLM extraction, and own LLM-wiki and agent-memory systems.
Data, Search & Databases
Broad experience with PostgreSQL, MySQL/MariaDB, MongoDB, SQLite, Redis, BullMQ, Elasticsearch, Solr, ClickHouse, Supabase, vector search (HNSW), Prisma, Drizzle and TypeORM. Includes zero-downtime Solr upgrades, large-scale document migrations and search stack management.
Security & Identity
Solid knowledge of OAuth, OIDC, PKCE, JWT, SSO, Supabase Auth/RLS, Auth.js, CSRF, CORS, supply-chain hardening and security audits. Practical experience implementing per-tenant JWT SSO and tokenless OIDC deployment CLIs.

Integration experience with Stripe, Redsys, Ingenico TPV, Holded, Resend, IMAP/SMTP and WhatsApp for e-commerce, ticketing and invoicing platforms.
Testing & Tooling
Proficiency with Vitest, Playwright, Puppeteer, Lighthouse CI, Sentry, PostHog and Turborepo/pnpm for quality assurance, performance monitoring and monorepo management.
Programming Languages
Primary languages include TypeScript, JavaScript, PHP, Python, SQL, Rust (Tauri 2), Go, C# and Bash, with the ability to pick up whatever the team runs.
Open Source & Developer Tooling
Author and maintainer of open-source projects including syntopica (agent-engineering stack), Vexa Insight (DMARC observability), eslint-plugin-code-policy (npm, 2,185 downloads in a month) and staffbase-cli/staffbase-utils deployment tooling adopted by six widget repositories.
SaaS Product Development & Founder Experience
Founder-operator since 2017 of multiple production SaaS products including DameTicket (ticketing with Redsys payments), InteliFactu (multi-tenant AI invoice processing) and tieneslavibra (artist-booking ERP/CRM), covering architecture, payments, hosting and on-call operations.
