• *OOO "PROKSI"* | April 2023 - April 2024, 1 year

  * Developed a document management system for creating *IE* and *reports*.
    Specifically, generation of `PKI CSR` certificates using a patched `OpenSSL`
    for Russian GOST standards, as well as their renewal and signing by various users.
    * Stack: `Go` `PHP` `Kafka` `PostgreSQL`
  - Rewrote a legacy monolith from `PHP` to `Go`, improving *performance* and *maintainability*.
  - Implemented a metrics collection system using `Grafana` and `Prometheus` for *enhanced* monitoring and insights.
  - Deployed a cloud and Kubernetes-ready infrastructure using `podman play kube`.
  - *Increased* system *reliability* by developing extensive *integration* tests.

• *DEMHACK 7* hackathon | 29 September 2023 - 1 October 2023

  * Developed a system for *analyzing* `DNS` requests and automatically 
    bypassing website blocks based on open lists of blocked sites 
    from various countries.
  * Implemented *automated selection* of working *proxies*
    by checking and caching their status.

• zfxtop

  * *TUI* utility in `Go` for monitoring *processor*, *ram*, *swap*,
    *battery percentages*, *temperature*, *disks*. Written 
    from scratch including the entire *TUI* and gathering

  * *World Smallest*^(~1.5kb)^, `JSX` based, Fine Grained Reactive `UI` Library.
    Super performant & Virtual DOM *Free*. 
    ([[https://www.reddit.com/r/javascript/comments/1b8j23r/hywerjs_world_smallest_1kb_jsxbased_reactive_ui|Reddit Post]])
    * Example frontend using it [[https://github.com/Lights-Social/lights-web-hywer|Lights]].
      And testing ground for changes.

• WaterMelonCoin

  * Compact *Proof-Of-Work* blockchain written in `C99`. Primarily created for reusable libraries in other projects.
    * [[https://github.com/ssleert/pyblock|PyBlock]] - similar project in `Python` worth remembering.

• supreme-octopus

  * Social network with `REST API`, implemented in `Go` and `PostgreSQL`, served by `Nginx` and deployed via `Docker Compose`.

• ccc

  * Cache cleaning daemon in `C`. Created to address inefficient memory freeing by older kernels causing heavy `swap` usage and slowdowns in *GTA V* on `Linux`. The game would even crash due to `oom` without `swap`.

  * [[https://github.com/ssleert/asyncness|asyncness]]
    * stackless coroutines with async/await for `C99`.
      Mostly used in microcontrollers.
  * [[https://github.com/ssleert/flick|Flick]] 
    * Social network with backend in `C++` using `fastcgi+http3` and `msgpack`.
      My playground for C++26 and various bleeding edge stack.
  * [[https://github.com/ssleert/watch|watch(1)]] - `watch(1)` for `OpenBSD`. Because it's not there out of the box.
