In this blog post, I discuss enhancing collaboration between data scientists and non-computational colleagues to ensure impactful work. I emphasize the importance of standardizing code initialization, involving non-coders in code reviews, empathetic communication across roles, and ensuring work is runnable on any computer. These practices aim to bridge gaps, reduce cognitive load, and foster mutual appreciation of challenges faced in data science projects. How can these strategies be implemented in your team?

In this blog post, I explore what brings me joy at work, highlighting my passion for setting high standards, mentoring, building tools, and engaging in meaningful projects at Moderna. I discuss the satisfaction derived from creating efficient solutions and the thrill of solving complex problems. Conversely, I touch on aspects of my job that are less joyful, like operational tasks and unnecessary complexity, which I strive to minimize through automation and effective processes. What brings you joy at work, and what removes joy from work for you?

In this post, I detail my experience building Pigeon Secure Notes, a secure note-sharing app, in under 15 minutes of coding time. I highlight the use of AI-assisted coding tools like Cursor and Claude Sonnet, discuss the challenges faced during development and deployment, and reflect on the benefits and limitations of AI-assisted programming for experienced developers. The post also touches on the importance of practical wisdom in software development and the thrill of building at "the speed of thought."

In this blog post, I introduce a new tool that uses LLMs to automatically generate explanations for Jupyter notebook cells. I discuss the motivation behind creating this tool, its current capabilities and limitations, and provide recommendations for optimal usage. The post also includes instructions on how to install and try out the tool for yourself. Curious about how it can streamline your data science projects? Why not give it a try?

In this blog post, I share my experience recreating Dan Ariely's Shortwhale using a tech stack that includes HTMX, SQLite, FastAPI, CloudMailin, and DigitalOcean. I highlight the transformative role of AI-assisted coding with Cursor, which allowed me to build core functionality in under two hours. The project, now live, was an experiment and a learning opportunity, emphasizing the speed and ease of AI-assisted web development. Curious about how AI can accelerate your web projects?

In this blog post, I share my experience integrating Pixi with AWS CodeArtifact, detailing the steps needed to configure Pixi for internal package publishing at work. I discuss the installation of pipx and keyrings.codeartifact, editing keyring configurations, and setting up Pixi's global configuration. The guide aims to help others overcome similar integration challenges (obviously without revealing company-specific details). Curious about how these configurations can streamline your development process?

Today, I learned that we can easily sync our local .env file with GitHub secrets using the GitHub CLI (gh). This method is much faster and less error-prone than manually entering secrets through the web interface. Curious to see how it works?

In this post, I explore how Cursor, an AI-powered IDE, transformed my coding workflow and supercharged my productivity. Learn about its standout features and why it's become my secret weapon for efficient development and writing. Are you ready to revolutionize your coding experience?

In this blog post, I explore the process of writing evaluations for LLM systems using pytest, aiming to move beyond subjective assessments to more structured testing. I detail the creation of specific tests to assess if LLMs can accurately determine documentation staleness, using various models and criteria. The challenges and insights gained from setting up these evaluations reveal the complexities involved in ensuring that LLMs perform as expected. Could this method enhance the reliability of your LLM evaluations?

In this blog post, I discuss the latest updates to LlamaBot, particularly focusing on the StructuredBot feature introduced by Elliot Salisbury. StructuredBot leverages JSON mode of LLMs for structured outputs, significantly simplifying the process of generating reliable and type-safe outputs without manual string parsing. I illustrate its application in an automated documentation checker and writer, enhancing productivity by integrating LLM-based and traditional programming methods. Curious about how StructuredBot can streamline your documentation process?
