Back to original languageAbout Iván
Senior full-stack developer, specializing in Laravel and distributed systems architecture. I mainly work on complex SaaS products, high-traffic platforms, and production infrastructures — from technical design to deployment.
I founded and built NodiTrack from scratch, a real-time vehicle tracking IoT platform capable of ingesting up to 4,000 requests/second per server, with a white-label multi-tenant architecture, a custom domain management system for reseller partners, and a complete Laravel + React + Inertia + Filament + Go stack.
In parallel, I served as CTO for Asesorr, a SaaS fintech dedicated to the Spanish market, where I led architectural choices, Verifactu integration (government electronic invoicing), load peak management, CI/CD pipelines, and the entire production infrastructure.
What I work on:
Robust Laravel APIs — REST architecture, queues with Horizon, Redis cache, workers
Real-time systems — WebSockets, events, data stream processing
Infrastructure & DevOps — Docker Swarm, Kubernetes, Traefik, CI/CD, automatic scaling
Monitoring & observability — Sentry, NewRelic, Grafana, advanced alerting
Performance optimization — bottlenecks, slow systems, high load
Multi-tenant & white-label architectures
I work on both greenfield projects and existing codebases to evolve or stabilize them. My approach is delivery-oriented: clean code, reliable systems, and a true understanding of the product challenges behind every technical decision.

- Comptoir du codeSenior FullStack DeveloperSOFTWARE PUBLISHINGDecember 2024 - Today (1 year and 8 months)Lille, FranceOrigami Marketplace (Comptoir du code Product) is a turnkey solution allowing clients to create and manage their own marketplace — product synchronization and import, payment management, fee splitting, advanced event system, etc.**Stack**: Laravel · Redis · MySQL · Docker · Kubernetes · Terraform · Grafana · PrometheusDevelopment & APII work on the continuous improvement of the main API — optimization of existing endpoints, development of new features according to client needs, and various technical integrations: PSPs, SSOS, payment systems, financial flow optimizations, among others. I also provide direct technical support to API consumers, assisting them with their integration and resolving the issues they encounter.Infrastructure & ReliabilityI oversee all production and staging environments via Grafana with Prometheus, New Relic, and Sentry, with a proactive alerting system configured to detect any anomaly before it impacts end clients. The goal is to anticipate incidents rather than react to them — zero surprises in production.Infrastructure management involves Kubernetes and Terraform, with particular attention to optimizing Docker images to reduce build times and attack surface. I also keep all dependencies up-to-date — application, system, and CI — with active monitoring of CVEs to identify and fix vulnerabilities before they represent a real risk.Optimization & PerformanceBeyond pure development, I regularly work on analyzing and optimizing internal processes — identifying inefficient workflows, reducing processing times, and improving overall system performance to ensure a smooth experience for the end-users of client marketplaces.
