Python developer · Pernik, Bulgaria

I write Python, ship it, and answer the pager when it breaks.

I'm Miroslav. These days I work at Optimal Industries, building tools and integrations on the Beacon Platform for an energy trading client. Before that I spent two and a half years on a live crypto trading project, wiring up integrations and fixing whatever broke in production.

Outside work I build apps like Cue and Snipify. That's where I learn the things the day job doesn't cover.

Cue

Episode alerts for anime, posted straight to your Discord server.

  • Re-reads every schedule in the background, down to every ten minutes in the last two hours before a show airs.
  • Retries a failed announcement, and never dumps a backlog into your channel after an outage.
  • Switches data source when one goes down, and keeps working from what it already knows when they all do.

Cue

Episode alerts for anime, posted straight to your Discord server.

Pick your shows, pick a channel, and Cue posts when a new episode is out. Air dates move all the time, so Cue keeps re-checking the schedule and correcting itself instead of trusting the first answer it got.

  • Re-reads every schedule in the background, down to every ten minutes in the last two hours before a show airs.
  • Retries a failed announcement, and never dumps a backlog into your channel after an outage.
  • Switches data source when one goes down, and keeps working from what it already knows when they all do.
  • FastAPI
  • SQLAlchemy
  • PostgreSQL
  • Redis
  • Alembic
  • Tailwind CSS
  • Discord

Woodrich

A bilingual site for a furniture workshop, with a gallery they manage themselves.

  • The workshop adds and rearranges its own project photos, with no developer involved.
  • Bulgarian and English throughout, down to the photo captions.
  • Phone photos are straightened and resized on upload, so nobody has to think about it.

This site

Plain pages built on the server, because a portfolio doesn't need anything fancier.

  • Projects, work history and the toolbox are all edited from a private admin panel; nothing is hard-coded
  • Every project has a personal page that tells the story behind it
  • Messages from the contact form land in an inbox with read, archive and search.

Apr to Jun 2026

Snipify

A URL shortener I built so I'd learn every layer myself.

  • Accounts, password reset and activation emails, and a dashboard of every link you have made.
  • Sessions expire after fifteen minutes and renew themselves, so a stolen one is worth little.
  • Per-account limits on each part of the site: tight on sign-in, generous on redirects.

About

Self-taught, and still at it.

I studied economic informatics at a vocational high school in Pernik, finished in 2023, and had my first developer job by that December. Most of what I know I learned on a live product, where mistakes showed up fast and I had to understand them properly to fix them.

I used to call myself a backend developer. These days that feels too narrow: I write bots, integrations, small tools and the services behind them. It's all Python, and the problem decides the rest.

In my free time I work on cars. It's closer to programming than it sounds: you read the symptoms, make a guess, test it, and change one thing at a time until the fault is gone.
