プロフィール
// 開発者

設計と デジタル体験

I am Jônatas Nascimento (Jhon), Software Architect and Senior Full-Stack Engineer focused on solving business challenges through scalable technology and high-performance architectures in the global market.

I have led highly critical GovTech and corporate SaaS initiatives. My deliverables include deploying asynchronous runtimes (Laravel Octane, Swoole, FrankenPHP) that maintain in-memory state for low-latency request handling, alongside AI R&D pipelines (OpenAI Assistants, RAG, database-connected Function Calling) secured via strict JSON Schema. I operate fluently on remote Linux servers via SSH, debugging transactional concurrency (race conditions) and building automated CI/CD pipelines.

My Core Stack

My engineering revolves around the modern Laravel/PHP ecosystem utilizing high-performance stateful runtimes, coupled with reactive front-ends built on React 19 and Inertia.js. My preference for Livewire and Blade is architectural, minimizing network overhead, retaining state cohesion, and maximizing critical render speeds.

Journey

The Journey

Great architectures aren't built overnight; they are forged under pressure. This is my background's evolution:

  • IT Technician

    Physical infrastructure services, local area networks setup, OS management, and private server administration.



  • The Forging (McDonald's)

    Operating under intense business pressure, managing concurrent workflows under strict delivery SLAs. This operational resilience serves as my SRE and fault-tolerance philosophical foundation.



  • The Base (SENAC)

    Academic background focusing on web systems fundamentals, database relational modeling, and monolithic software design patterns.



  • End-to-End Architect (Freelancer)

    Full technical ownership of design, implementation, and deployment of end-to-end platforms (Cafeteria Damore, JYNSGE News), integrating Stripe and Supabase under automated CI/CD.



  • Tech Lead & Architect (LUMEN Consultoria)

    Lead architect for B2G SaaS Enterprise Platform Lumen. Upgraded legacy runtime to Laravel Octane + FrankenPHP, cutting response latency by 50%. Led AI R&D for structured document compilation and mitigated critical concurrency/race conditions on legacy systems.



  • The Anchor (UNIVESP)

    Bachelor's Degree in Computer Engineering, cementing deep knowledge in computer hardware, digital logic, and low-level system designs.
