Why I Built Purple — And Why It Took 20 Years to Get Here

I've been thinking about AI since before it was cool to think about AI—studying neural networks, formal logic, and operating system internals at my university in Katowice. At the time, it seemed almost impossible that these fields would ever converge, but they did. The wait, however, felt incredibly long.My early professional experience taught me relentless discipline: building commercial software (around 2001), generating revenue with mobile apps in foreign markets (China, 2007), and iterating through diverse tech stacks at companies like EPAM, Uber, and Pearson.

Integrating locally running LLM in Go tools to scan Golang modules

I was writing Go applications since 2016 and I was able to go thru various dependencies management systems including famous at some point DEP and now built-in go modules. While go dependency management came long road in language history it still has one major flaw – all dependencies are downloaded from Internet, mostly from github […]

Automating Go multi-project builds with autobuild-go tool

I’m excited to share the release of Autobuild-Go, a tool designed to automate and streamline the build process for Golang microservices, particularly in environments with monorepos. This tool emerged from a need to handle multiple microservices more efficiently, eliminating the manual overhead that comes with building them one by one. Why Autobuild-Go? In our case, […]

I built my own LLM chat, and it’s running offline

Recently, I took on a project to build AChat, a chat application that runs on my local network and operates entirely offline. The challenge was to utilize a powerful AI model, Meta’s LLaMa, while keeping everything on-premise, without relying on cloud services. It turns out, when you have a GPU-equipped server at home, it’s entirely […]

Automating Video Conversion for Amazon with a Custom Golang-based Tool

I recently built a video converter application for my wife, who works with Amazon and regularly needs to convert videos into various formats and resolutions for different placements on the platform. Manually adjusting video settings for each requirement was time-consuming and error-prone, so I decided to automate the entire process for her. The Problem: Repetitive […]

Rate limiting and how to handle it on the client side

When publishing an API on the internet, we open ourselves up to a wonderful world of users, but also a world full of threats. Proper design patterns, good security practices, and audits and penetration tests help mitigate many of the risks associated with open API access. There are many design patterns and best practices for […]

Embedding assembly into Golang

Go is very powerful language, but even with all this power time to time we need to go lower level and write some “kosher code” that will be hyper optimized either for memory usage of performance. In Golang we do have two interfaces to do so, depending on the level we want to write our […]
