I build my own tools
When a task keeps repeating, I write a Python or SQL script for it. I've built scrapers, internal tools, a web app and a game backend.

Python developer building automation, integrations and internal tools.
16 months of paid, part-time remote Python work at BuiltMind, where I wrote 100+ production scrapers on AWS Lambda and internal tools. I co-founded CornerForge and developed 4Corners, now on Google Play. I also built Trackora, a full-stack TypeScript portfolio tracker you can try here.

What I bring to a team
Paid Python work, projects that are live, and years of leading shifts in production.
I lead people under pressure
As a shift manager I'm responsible for people, output and quick decisions under time pressure, and I hand work over clearly between shifts. Shift work is fine for me too.
Projects you can try
4Corners is on Google Play, and Trackora — the portfolio tracker I use every day — has a browser demo with invented data.
Experience
Jan 2023 – Apr 202416 months · part-time, remote
Junior Data & Python Developer
BuiltMind — proptech data, Prague
- Wrote and maintained 100+ scrapers on AWS Lambda, plus internal tools: Scraping Cleaner and a daily data-quality check (see below).
- Went from my first scraper to internal tools used by the whole team in 16 months — reference letter from the Operations Manager.
Jul 2025 – presentown studio, alongside full-time job
Co-founder & Developer
CornerForge — two-person indie game studio · 4cornersplay.online
- Shipped 4Corners to Google Play (iOS in TestFlight): gameplay, backend (leagues, cloud save), ads & IAP, releases and store compliance.
- Maintain the game after release: crash reports, remote config for difficulty and economy, release audits.
- Now developing our second game, Spin Lock — a one-tap timing game with a three-phase boss; difficulty evaluated with a simulator, real-player testing still needed.
2016 – presentfull-time
CNC Setter / Shift Manager
MGG, Třešť
- Started as a regular setter and was given more responsibility over the years; today I run afternoon and night shifts of 10–15 people.
- First point of escalation when something goes wrong — decide fast, fix it, then work on preventing a repeat.
2012 – 2016education
Mechanical Engineering
Secondary Technical School (Střední škola průmyslová, technická a automobilní), Jihlava
I am a self-taught developer — courses, a part-time job at BuiltMind, then my own projects.
Selected work
Professional and independent projects. The game is in the store, the web app runs in your browser, and the internal tools are shown as interactive re-creations.
What I built at BuiltMind — data flow

Zdeněk was instrumental in optimizing our data processing workflows, which enhanced our team's productivity and data quality.
Real-estate data pipelines COMPANY CODE
As a Junior Data & Python Developer I collected, cleaned and checked the new-build housing data that the company's products are built on.
- Scrapers of developer websites on AWS Lambda: asyncio/aiohttp, retry decorators, a mapping of each site's fields onto one shared schema, output to S3.
- Built a daily data-quality Lambda that walks the Notion project database via API (with pagination) and flags projects missing a developer, address, coordinates or a scraper.
- Worked with PostgreSQL and debugged other people's Python code.
The demo runs entirely in the browser with invented prices, trades and company financials — no real account or money.
Trackora DAILY USE
A full-stack web app I use every day to track my stocks and crypto, in English and Czech. It syncs Trading 212 through its API, imports XTB (.xlsx) and Revolut (.pdf) statements and keeps every position consistent with a transaction ledger; on top of that it shows returns, dividends, company financials and data for the Czech tax return.
- Resumable broker sync and statement import with duplicate detection; scheduled price refresh with a provider fallback chain and a shared cache. 620 automated tests (Vitest), run by a CI workflow in the repo.
- PostgreSQL with row-level security; triggers keep positions and cash consistent with the transaction ledger. Broker API keys are encrypted at rest (pgcrypto + Vault).
- Company financials cached in PostgreSQL and refreshed by a nightly GitHub Actions worker; a newly added company is fetched on demand, with a per-user quota.
- Domain logic as pure, tested functions: Czech tax rules (per-lot FIFO with ČNB exchange rates, the 3-year holding test) and a fair-value calculator (DCF, valuation multiples).

4Corners LIVE ON GOOGLE PLAY
A tactical block puzzle with 150 campaign levels, survival mode and weekly leagues. I'm the primary developer — gameplay, backend services, monetisation and releases — with substantial AI assistance from Claude Code and Codex.
- Leagues & leaderboards backend on Unity Gaming Services — server-side Cloud Code (JavaScript) for score submission, cohorts, bots and weekly league rollover.
- Cloud save with merge rules, snapshots and versioned save migrations; Google Play Games / Game Center sign-in and server-side account deletion.
- Adaptive difficulty (skill rating, retry assist) plus editor tools: a campaign simulator and a level-balance validator for generated levels.
- Monetisation & monitoring: ad mediation, in-app purchases, Firebase Crashlytics and Remote Config, GDPR/US consent flow.
- Testing & releases: 3,000+ EditMode/PlayMode tests, scripted Android & iOS release builds, written release and crash audits.
Public C# case study: prevent a fresh anonymous save from replacing advanced account progress after sign-in. Extracted decision rules, an executable example and boundary tests; the full game stays private.

Scraping Cleaner
A Streamlit app I built so the team could check and fix whole batches of scraped files in a few clicks instead of opening them one by one in a spreadsheet.
- Loads a folder straight from S3 (paginated listing) or an uploaded ZIP.
- Checks for duplicate IDs and missing columns across all files and lists the problem files.
- Bulk fixes — drop, rename or add a column, rename files — and downloads the result as one ZIP.
Public edition: reviewed and repaired for release in 2026, with regression tests and local environment configuration.

Spin Lock IN DEVELOPMENT
A one-tap timing game: a needle sweeps around a lock and you tap when it reaches a target. A campaign with changing mechanics and boss encounters, currently in development.
- Public balance simulator: real C# game rules tested against four assumed player profiles. Seeded runs, retry analysis and JSON reports make difficulty changes measurable and reproducible.
- Small Python tools for generating sound and VFX assets.
Standalone .NET sample with regression checks. Player profiles are design assumptions; real playtests are still needed.

Chrone.cz MY FIRST PROJECT
When I was a teenager, I ran a Czech & Slovak gaming portal with its own game servers. It lasted about three years and covered its own costs.
- Game servers: about five public Counter-Strike 1.6 servers with different game modes (e.g. Jailbreak, Furien, Dust2 Only) and a Minecraft world built with a small team, each with its own regular players. When the portal stopped being profitable, I shut it down.
- Chrone Studio: a few months later I reused the name for a new idea — managing a small group of streamers (League of Legends, CS:GO, Dota 2, SMITE). I handled graphics, stream setup and everything around the streams; they created the content. Our first official stream (Nov 2015) had 186 live viewers.
- What I learned: the studio ran on verbal agreements and wound down after about half a year. Clear rules and commitments agreed up front matter more than enthusiasm.

How I work
Own the result, check your work, and stay calm when something breaks.
If it breaks, it's mine
After a release I watch the crash reports and fix what I find — I don't wait for someone else to notice.
Stabilise, then find the cause
I investigate root causes and add checks to reduce repeat failures.
I automate repetitive work
Scraping Cleaner, zipfill, level generators, build scripts — when something keeps coming back, I script it.
AI-ASSISTED, HUMAN-OWNED
AI-assisted development, with review and testing
Claude Code and Codex help me move fast; the design decisions, review and accountability stay with me. I treat AI output like a colleague's pull request: read it, question it, test it.
- Specwrite down the goal and constraints
- Plansplit into small, testable steps
- Buildpair with the AI, give it context
- Reviewread the diff, question it
- Testunit tests + a real device / browser

I'm looking for remote work in Python development, automation, integrations or application support. I'm also open to game development roles using Unity and C#. Based in the Czech Republic (CET/CEST); shift work is fine.
