I'm Oscar, a senior developer based in Mexico with years of experience working remotely for US-based companies. My profile is rare because I sit at the intersection of engineering, systems thinking, design, and leadership.
I don't just write code — I build maintainable systems that scale. I think in workflows, failure points, and automation opportunities. When something breaks, I don't just fix it; I prevent it from breaking again.

mindset: "Build once, scale forever"
};This is where I operate at a senior/lead level. I build and maintain complex WordPress ecosystems — not just websites, but interconnected systems that power businesses.
Deep expertise in the core technologies that power modern WordPress development.
Building custom themes and templates from scratch, tailored to specific business needs.
Understanding the technical side of SEO and deploying without breaking rankings.
Integrating and maintaining complex marketing technology stacks.
Taking full ownership when things go wrong — debugging fast and preventing repeats.
Acting as the bridge between development, SEO, and marketing teams — even unofficially.
Understanding the full process
Where can this break?
What can be automated?
Will this scale?
This isn't a hobby — it's where my imagination and systems brain collide. I design full game architectures with studio-grade thinking from day one.
Building reusable, testable modules that can be understood by future contributors. Clean architecture from the start.
Never trust the client. All critical game logic runs server-side with proper validation to prevent exploits.
Robust data storage with proper error handling, session locking, and data migration strategies.
Designing balanced economy loops with proper sinks and faucets that keep players engaged long-term.
Creating worlds that feel handcrafted through algorithmic generation — biomes, terrain, and dynamic content.
Designing clear player experiences from the first moment. If players are confused, the game has failed.
"My goal isn't a small game — it's ownership."
I treat Roblox projects like real software products, not hobby scripts. Every system is built with future contributors in mind, because the end goal is building something that outlasts me.
My approach to development is shaped by a few core principles that guide every decision I make.
I break down complex problems into manageable pieces. Every project has clear milestones, every system has defined boundaries, and every process has documentation. Chaos is just unorganized complexity.
The devil is in the details, and that's exactly where I like to work. Edge cases matter. Error messages matter. The experience of the next developer who reads my code matters.
Good outcomes come from good processes. I invest time in building systems that prevent problems rather than constantly firefighting. A well-documented process is worth more than a brilliant individual fix.
Not in a way that blocks progress, but in a way that demands quality. I believe in doing things right the first time, investing in clean architecture, and building things that I'd be proud to hand off to someone else.
If it's not documented, it doesn't exist. I ask for better prompts, write clearer READMEs, and create processes that can be followed by anyone. Knowledge shouldn't live only in one person's head.
A selection of projects that showcase my approach to building systems. Focus is on architecture decisions and real impact.
Built and maintained a network of 20+ WordPress sites with shared components, centralized updates, and integrated marketing stack.
Designed and implemented end-to-end lead tracking from form submission to CRM with full attribution and reporting.
Designing a procedurally generated survival game with persistent world state, modular building systems, and scalable multiplayer.
Designed a balanced economy system with multiple currencies, progression loops, and anti-inflation mechanics.

Whether you need a WordPress ecosystem architect, a game systems designer, or someone who thinks in processes and scalability — I'm available for remote opportunities with US-based companies.
