Czech Republic

Hi, I'm Pavel, a software developer from the Czech Republic with roughly nine years of programming experience under my belt, most of it being remote. During that time I have worked variety of languages, frameworks, and teams.

Languages

TypeScript

My go to for front-end work and plenty of back-end too.

C#

Language I know very well but don’t use as much anymore.

Go

I had to picked it up for a project using gotd/td and ended up loving its simplicity and speed.

Ruby

Mainly used in combination with Rails.

PL/pgSQL

I wouldn’t have chosen it on my own, but a postgraphile heavy project made me learn it.

Nix

I use nix-darwin and nix in its various forms can be found in almost everything I do.

Lua

I got into Lua while hacking on neovim plugins.

Bash

I've written my share of Bash scripts for various tasks.

Hobby Languages

Sometimes after entire day of programming at work I like to program some more at home. Here are some languages I play with.

Zig

Picked to learn low-level language, I really liked it but for now I switched to Rust.

Rust

Language I am activelly learning right now.

Frameworks & Technologies (non-exhaustive)

React

Deeply familiar with React and popular frameworks like Next.js and Vite.

GraphQL

Experienced with GraphQL tools including PostGraphile, HotChocolate, and pg_graphql.

Postgres

I am familiar with postgres and its advanced features like functions, views, RBAC, RLS, plugins etc.

DevOps

I am interested in entire software development lifecycle and don't mind being involved in other parts than just programming.

Telegram

I have experience with client/bot API and I am familiar with basic bot development. In the future I would like to learn TON contract development.

Solana

I have basic experience with interacting with Solana programms and integrating web3 wallets.

Testing

I have experience with unit, integration and end-to-end testing (browser automation).

GIS

I have experience with interactive geospatial data visualization.

Web scraping

I have experience with extracting data from websites and converting them into APIs.
