Functional Programming

For me, Functional Programming is a powerful toolkit for creating clear and controllable software. It enforces a discipline that helps me stay focused by breaking large problems down into a series of small, predictable data transformations. I can build a repertoire of sharp, pure functions, where each function is a self-contained unit that only has to be concerned with its inputs and outputs. At a higher level, this repertoire can be composed into a fluent, domain-specific language (DSL)—a powerful technique for modeling complex logic, which I've often found tempting for things like rules-based mathematical calculations. This makes unit testing incredibly straightforward, as there are no hidden states or external dependencies to manage. The paradigm's greatest strength is how it controls complexity by keeping side effects at bay; by isolating interactions with the outside world, the core logic of the application remains simple and predictable. This approach leads directly to software that is not only highly maintainable and robust, but also easier to reason about and built to last.

Machine Learning & Language Exploration

My current focus is on deepening my understanding of the modern machine learning landscape. My journey began with computer vision, a necessity for my work, which first sparked my interest in how machines can interpret real-world patterns. However, the recent revolution in Natural Language Processing, particularly with transformers, captured my full attention. The realization that we can now teach computers to understand and articulate complex ideas connected with a lifelong fascination I've had with language. This has pivoted my exploration from a professional necessity into a deep, personal quest to understand how these interconnected fields are fundamentally changing how we interact with technology.

Rethinking the Monolith

A core principle in distributed systems is that network calls are inherently expensive, as the process of serializing, sending, and deserializing data introduces significant latency. While microservices are invaluable for enabling team autonomy, they intentionally accept this performance cost to gain organizational scale. My experience has shown, however, that many projects benefit more from computational efficiency than organizational separation. A carefully designed monolith delivers immense performance by keeping communication in-process, which not only improves speed but also creates a fundamentally simpler architecture. With a single codebase, tasks like debugging, troubleshooting, and overall maintenance become far more direct and manageable.

Formless

After more than a decade of writing software, I've learned that rigidly applied structure can be the single most limiting factor in finding a truly great solution. When we force a problem into a preconceived pattern, we often miss the simpler, more direct path that's waiting to be discovered. My approach is to instead derive the structure from the first principles of the problem itself. I see a deep parallel to the concept of 'Jū' (softness), the martial arts expression of Yin, in disciplines like Judo and Jujitsu. True mastery isn't about meeting force with force through rigid techniques; it's about yielding and adapting to the problem's own energy. The ultimate expression of this mastery is to be 'like water.' It acknowledges that we can only experience the computational realm indirectly, so a solution's form must emerge from a careful, first-principles evaluation of the problem, not a rigid template. This is the essence of my approach to software. It's not about forcing a design that we perceive as elegant, but about carefully solving the problem and respecting the structure that naturally emerges. A solution built this way is fundamentally more robust, carrying fewer bugs and built to last a long time.

UI & UX Understanding

I've had the opportunity to build user interfaces across a wide spectrum of technologies, from native desktop and mobile with WPF and MAUI to the web's foundational trio of HTML5, CSS3, and ECMAScript 6+, which underpins modern frameworks like React and Angular. While these domains can seem worlds apart, what years of working through their unique challenges has taught me is that they all share the same fundamental problems of state management, performance, and intuitive user interaction. This long process of solving these core issues in different contexts is what builds the hard-earned, framework-agnostic intuition needed to solve truly difficult problems. It is this understanding that allows me to build dynamic UIs capable of meeting any kind of demand. I don't back down from an interesting challenge; I strive to not only deliver on a user's creative vision but to enhance it, creating solutions that are simpler, more effective, and robust.

My Renewed Fascination for Algorithms

My work in computer science has sparked a renewed fascination with the mathematics that underpins it all. Unlike my time in college, this is a deep and genuine curiosity that I now have the freedom to pursue for a lifetime. Studying the algorithms behind modern AI and distributed systems has led me back to the fundamentals—revisiting graph theory, linear algebra, and the calculus that powers transformers. It reveals that mathematics is a different and powerful lens for viewing computation; when you learn to work with this perspective, building effective software becomes a more direct and intuitive process, bringing us closer to the reality of computer science as a realm of its own.

Professional Recommendations

I had the distinct pleasure of working closely with Robert Long for over four years, and I can confidently recommend him as one of the most talented software builders and technical leaders I've ever collaborated with. Robert possesses a rare ability to solve deeply complex technical problems that frequently challenge other senior developers. He is not just adept at implementation; he is a true technical visionary who consistently looks beyond the obvious to recommend brilliant, game-changing alternatives. Robert is exceptionally skilled at researching and integrating bleeding-edge technologies to deliver solutions that redefine product capabilities. His recent work on an innovative AI project stands as a testament to his impact. Robert engineered a proof-of-concept that rapidly exceeded all expectations, accomplishing what was previously deemed impossible and revolutionizing a core aspect of our product. The result was so compelling that multiple company executives immediately launched a full development initiative to bring his design to market. Robert's extensive experience in AI, from deep research and analytics to using it for rapid code generation, allows him to operate with incredible speed and scale. Beyond his technical prowess, Robert is a phenomenal collaborator. He excels at sharing knowledge with the team, leading design sessions that explore and evaluate multiple technologies—meticulously weighing the pros and cons before guiding the team toward the optimal architectural path.

Robert oversaw a key project for the Pitzer College Office of Career Services. We were about to lose an important student resource; a directory of alumni and parents/family members who students can contact for career conversations. Robert led an effort to build a platform "from scratch" for our students. He coordinated a process with the offices of Advancement, Information Technology, and Career Services to create this directory and make it available to the community. Throughout the process, he was kind, focused, detail-oriented, and an easy partner with whom to work.

I have known Robert Long for about 4 years. I worked with him as he provided his advice and programming ability to set up a tracking system for our Institutional Research Board (IRB) application system at Pitzer College. The IRB application review is a Federally mandated program for all colleges and universities that do research with human subjects. Robert listened to our needs and provided us with the means to meet our needs, along with giving us an easy to use site for our end users. The key fact is that it is not an easy task for an IT professional to translate what a non-IT person is trying to accomplish. Robert is good at this translation. He was thoughtful, always attentive to our needs and professional.
