About Sergio
Are you looking for more than just code? I provide high-performance technical solutions by bridging the gap between sophisticated software development and rock-solid system infrastructure. Whether you need a scalable web application, a custom Linux environment, or high-throughput backend systems, I deliver production-ready results focused on efficiency and security.
Core Expertise & How I Can Help You:
Full-Stack Development: I build modern, SEO-optimized, and lightning-fast web applications using Next.js, React, and TypeScript.
Systems Programming & Low-Level: With deep expertise in C and C++, I develop performance-critical components. My experience building custom Linux distributions ensures I understand the OS from the kernel up—perfect for specialized hardware or high-security needs.
Backend & Automation: Expert in Python (Django/FastAPI) and currently expanding into Rust and Go for memory-safe, concurrent services. I specialize in complex API integrations and data processing.
Infrastructure & Self-Hosting: I don't just deploy to the cloud; I understand the metal. From managing high-end Xeon/ECC environments to configuring RAID/SAS storage and secure Networking, I can help you cut costs by optimizing your on-premise or hybrid cloud infrastructure.
Why Choose Me?
Versatility: I can jump from high-level UI/UX logic in Next.js to low-level system debugging in Linux without missing a beat.
Problem-Solver Mindset: I don't just follow tickets. I analyze your business needs to suggest the most cost-effective and scalable stack.
Advanced Systems Knowledge: My background in networking and server hardening means your project will be secure by design, not as an afterthought.
What I Deliver:
Custom Enterprise Software & Web Platforms.
Linux System Hardening & Bespoke Distributions.
Automated Scrapers, Bots, and API Middlewares.
Server Migration, Virtualization, and Infrastructure Maintenance.
