lukaszraczylo/README.md

Hi, I'm Lukasz

I'm London based, contractor, "Head of Magic and Wizardry" ( because job titles are overrated ). Dealing with the cloud, kubernetes, microservices, and all the other buzzwords on a daily basis. Responsible for architecture, development, and maintenance of the systems which are running on the edge of the technology. Most of my code is private ( either mine or business choice ) but bits which are public are free for grabs or contributions.

Bit of tech writing

Selected public projects

  • Semantic Version Generator - Golang simple tool to generate semantic versioning based on the git history. It can be used as a standalone library or github action, simplifying the process.
  • Go Simple GraphQL library - Golang simple graphql library, optimised for the maximum speed and minimum allocations. Unlike the other libraries - the queries are passed as they are, without types assignment which makes it much easier to use from the development perspective. Projects using this library easily handle tens of thousands of requests per second with minimal resources.
  • Kubernetes Jobs Manager Operator - Golang kubernetes operator to manage jobs in the kubernetes cluster. Its sole purpose of existence is to allow for advanced workflows to be executed in user specified order and with interlocked dependencies on groups / jobs.
  • GraphQL monitoring proxy - Golang graphql proxy which allows for the generation of prometheus-friendly statistics on the execute queries. It allows for caching, the RO/RW separation, rate limiting, banning specific users, blocking schema introspection and so on - at the speed of light. It was developed as a protest against the Hasura team putting basic monitoring features behind the paywall, and extended with additional features from the paid version down the line. The proxy is hyper-optimised and running on the real-world production systems, serving tens of thousands of requests per second with 3cpu and 15mb of RAM on Raspberry Pi.
