good at full-stack development and systems engineering. I have built apps from scratch and scaled them, wearing many different hats from front-end UX to low-level systems programming.

Computer Science undergraduate at the Federal University of Espírito Santo (UFES). Mainly interested in Theory of Computation, Algorithms, Compilers, Distributed Algorithms, and Cryptography. Currently working as a research assistant in cryptography, specifically on zero-knowledge proofs. My work turns on two axes: computing and mathematics. I’ve spent years building a firm base in both. I grew up between Brazil and the United States, speaking Portuguese and English as first languages. I now study Computer Science at the Federal University of Espírito Santo (UFES), on track to graduate in December 2026.

Self-taught Haskell and NixOS free software developer since 2015, former self-taught OCaml software developer from 2005 to 2015, and self-taught GNU/Linux system administrator since 2010. Most of my work so far has consisted in understanding and (re)implementing algorithms found in scientific papers, with my main focus being on correctness. I do my best to understand what I do. I'm passioned by developing algorithms or fixing bugs. I am hardworking and a fast learner with communication skills for teaching and being accurate on technical matters.

My background's in mathematics, but I have extensive programming and CS knowledge; as well as an interest in solving challenging technical problems. I've focused some attention on AI as of late, specifically markov decision processes and variants of these... Besides this I've implemented a few things from scratch (dnn, hopfield, transformer, etc), wrote a virtual assistant, have done work in computer vision, have written a peak detector, have implemented a 3SAT solver, parallel FFT algorithms on GPU and TPU.

Hello, I'm Drew Roberts. With a passion that has grown over 15 years, I've navigated through the evolving landscape of web development and AI-driven applications, carving out a niche that blends innovation with practicality. My journey began with a solid foundation in PHP, a language that has been a constant companion through my career, offering me the versatility to build robust backend systems. By 2013, I embraced Laravel, captivated by its elegance and the way it streamlined complex coding tasks. This was not just a shift in tools but a leap towards more sophisticated, scalable web applications. Laravel's expressive syntax and its ecosystem became a significant part of my development process, enabling me to deliver exceptional web experiences. The frontend world was not left untouched by my quest for growth. React and Vue caught my attention from their inception. These frameworks transformed the way I approached frontend development, allowing me to create interactive and dynamic user interfaces. The blend of React's powerful composition model and Vue's approachable syntax enriched my projects, making them not just functional but also engaging. In 2020, I became a fan of the TALL stack - Tailwind CSS, Alpine.js, Laravel, and Livewire - which resonated with my philosophy of creating efficient, maintainable, and beautiful web applications. It signified a full-circle moment, integrating my backend expertise with a modern frontend approach in a seamless, cohesive manner. More recently, AI and LLM technologies have become a core part of my work. I integrate OpenAI GPT, Claude, and other LLM APIs into production applications - building AI-powered workflows, intelligent chatbots, agentic applications, and AI layers that sit on top of existing systems. My approach to AI is practical and production-focused: prompt engineering for reliable outputs, deterministic logic with AI guardrails, and scalable architectures that keep AI features maintainable. I also leverage AI vibe-coding tools like Claude Code, Gemini, Lovable, and Replit to rapidly prototype and ship production-quality applications. Throughout my career, my projects have been supported by robust databases and servers, ensuring that my applications are not just visually appealing but also performant and reliable. MySQL, PostgreSQL, and Supabase have been my go-to databases, offering the reliability and flexibility needed for complex data management. On the server side, I've leveraged the power of Apache and Nginx on AWS, GCP, and DigitalOcean, ensuring that my applications are delivered to users quickly and securely. Today, I bring together full-stack web development and AI engineering - from Laravel and React/Vue frontends to LLM-powered backends and agentic workflows. Each step of my career has been guided by a desire to learn, adapt, and apply the best technologies to solve real-world problems. Whether it's a complex web application, an AI-integrated platform, or an intelligent automation system, I deliver production-ready solutions that work. My GitHub handles, "tipoff", "drewroberts", and "roberts", showcase extensive repositories echoing my deep technical proficiency and my zest for community-driven contributions.
