Carlos Indriago

Software Architect · Enterprise SaaS Builder · Open-Core


I don't just write code — I engineer resilient systems. With over 15 years of experience, I specialize in designing high-availability backend architectures, multi-tenant SaaS platforms, and security-focused infrastructure. From resolving database bottlenecks to implementing Clean Architecture in distributed systems, my focus is on building software that solves complex business problems at scale.


🚀 Architectural Showcases

Project & Domain Engineering Impact Stack

Multi-tenant CRM with Open-Core model. Built strict per-organization data isolation using PostgreSQL RLS + JWT, enforced at Server Action level.

Data Engineering
EAV Architecture Optimizer. Built an indexing engine that projects transactional data into flat analytical tables asymmetrically, reducing query times up to 10x (O(1) vs O(N)). PHP, MySQL, Data Projection

🛠️ I also maintain Open Source DevOps tools like Ulauncher Docker Extension and hardware-level Linux integrations like TuxKeysToys.
