I have worked at over a dozen companies large and small, in a handful of different domains. Also participated in hundreds of interviews, about half-and-half as the interviewer and the interviewee. I have given dozens of talks and training sessions on a variety of topics, mostly focusing on distributed systems, caching, and testing. My top skills are Java, SQL, testing, and refactoring. I have experience with formal academic and professional mentorship, and would love to help you skill up, solve a problem, or just nerd out with you today!
#### Empowering Developers: From Novice to Expert Are you looking to embark on your software development journey or elevate your existing skills? With expertise in Python, Java, TypeScript/JavaScript, Rust, Dart/Flutter, Haskell and Clojure. I offer comprehensive guidance tailored to your needs. My approach combines technical proficiency with essential soft skills, ensuring you're well-equipped for the industry's challenges. #### Beyond Learning: Practical Implementation For those seeking hands-on assistance, I'm available for projects of various scales. Whether it's implementing new features, debugging complex issues, or optimizing database performance with Postgres and MongoDB, I bring a wealth of experience to the table. My commitment to clean code, SOLID principles, and multi-layered architecture ensures robust, maintainable solutions. #### Navigating the AI Landscape In the rapidly evolving field of artificial intelligence, I offer insights into the workings of Large Language Models (LLMs) and their applications. From crafting effective prompts to exploring the potential of open-source models, I can guide you through the intricacies of AI integration in your projects. Let's unlock the power of AI together and push the boundaries of what's possible in software development. #### Cutting-Edge Methodologies My unique approach to software development incorporates algebraic design principles and property-based testing. By employing a multi-tiered model that seamlessly integrates declarative functional programming, object-oriented design, and imperative coding, I create systems that are both elegant and efficient. This methodology allows for clear, abstract specifications that translate into practical, high-performance code. *Technologies / Skills* - Clean Architecture - Python - Java - TypeScript/JavaScript - Rust - Dart/Flutter - Haskell - Clojure - PostGreSQL - MongoDB - SOLID principles - TDD / BDD / ATDD - LLMs - ChatGPT, Claude, Llama
https://nftcoffee.dev/ I fell in love with coding at age 13 and haven't looked back since. I've learned lots of languages along the way, but I'd have to say my favorites are Solidity and JavaScript. I'm a huge proponent of science/tech education, free speech and digital privacy rights.
