Hire the Best TypeScript Developers
in the Czech Republic

Are your employees spending more time fighting spreadsheets, copy-pasting data, and wrestling with off-the-shelf software than actually doing their jobs? ​When standard tools stop fitting your unique workflow, your business hits a ceiling. You start losing information, making mistakes, and wasting money on manual work. ​I build custom web applications, internal portals, and CRMs that adapt to your business — not the other way around. I don't just write code; I digitize your daily operations to eliminate chaos and help you scale without constantly hiring more managers. ​I know exactly why software projects fail: developers rarely try to understand the actual business. I take a different approach. For instance, when I built a custom CRM for a translation agency, I didn't just take a list of features. I dug into their daily bottlenecks, automated their task distribution, and delivered a system that saved them hundreds of hours. If you are tired of technical headaches and need a reliable system that actually works for your team, let's talk. ​Send me a brief message about the biggest bottleneck in your current process, and I'll let you know how we can fix it.

Who I usually work for: data companies, individuals who want to automate their trading, and content creators who want to sell merch without getting overwhelmed with the complications regarding running web applications & compliance. What I offer: → Web Scraping - Full pipelines with detection-aware patterns (header alignment, IP rotation, rendering, proxies), plus data quality checks and a clean final dataset. → Trading indicators, strategies, backtesting, bots and alert systems - Tools: TradingView (PineScript), FxReplay, Freqtrade, StrategyQuant (consultations), 3Commas, MetaTrader, Telegram alerts, Polymarket, hosting on Zoner or Alibaba Cloud → E‑commerce setup - Platform setup (Shopify, WooCommerce, Fourthwall, OpenCart...) + integration to producers (Printify) + sample designs from a subcontractor (I manage design quality and final delivery, optional hosting) → Full Eshop Platform Management (of my own design) - End-to-end: DNS registration, product design & manufacturing (via Printify), ordering, payments, and customer support (with my LLC/agency). What I don't offer: → unauthorised penetration testing or scraping of publicly unavailable (paywalled/hacked) content → my own live strategies - you have to define the trading behaviour, I will code it → untested, poor-quality AI code (AI may be used, but I am fully responsible for the quality and will verify it) or vulnerable code → legal or tax consulting Schedule calls anytime in European waking hours.

Hi, I'm Kilian — a full-stack Web3 and AI developer based in Prague, Czech Republic with a proven track record of shipping products and winning hackathons. I've shipped 11+ projects across Web3, SaaS, desktop apps, and games — working with technologies like NextJS, TypeScript, Solidity, Rust, Tauri, and Svelte across multiple blockchains including Ronin, Polkadot, and Base. Hackathon Achievements (6 hackathons, 8 awards): - ETHGlobal Cannes — Best Consumer App on Ronin, 1st Place - Polkadot Web0 Berlin — Main Track Winner + Ink Alliance Bounty + UX Bounty (3 prizes) - ETHWarsaw — Best Mini App on Base, 1st Place - ETHGlobal Buenos Aires — Best Consumer/AI dApp on Ronin, 2nd Place - Sub0 Symbiosis — XX Network Bounty, 1st Place ($3,000) - Polkadot Cloud Hackathon — Community Roots Meetup Prize Notable Projects: - Ronkeverse — Built NFT casino games, landing pages, leaderboard systems, and backend infrastructure on Ronin - Allstake — Sole developer of a cross-chain Web3 platform with NFT marketplaces, staking, auctions, and raffles - Minefield Navigator — First developer hire for a SaaS platform helping e-commerce sellers expand into Europe - The Agency — An autonomous multi-agent AI system built on Claude Code My core stack: NextJS, TypeScript, Solidity, Tailwind CSS, and smart contract development.

Let's connect and build something great together.

I've been designing and building digital products since 1998 — back when we were still arguing about table-based layouts — so when I say I've seen the industry evolve, I mean it. These days I work at the intersection of UI/UX design and front-end development, which means the people who hire me get both halves of the equation without the usual handoff friction. My focus is on products that look considered and work properly: web applications, admin dashboards, marketing platforms, and mobile-first experiences. I'm strongest in Vue 3 + Nuxt / Quasar, React + Next.js, Astro (native or web) and TypeScript, though I've worked across enough stacks over the years that dropping into an unfamiliar codebase doesn't faze me. I also use AI tooling daily — not as a shortcut, but as a way to move faster and think more clearly, while keeping quality where it needs to be. The way I work is probably best described as structured but collaborative. I'm a firm believer in understanding the brief properly before touching anything — a short, honest conversation at the start saves everyone a lot of time later. From there I work iteratively: wireframes to prototype to production, or wherever in that chain you need me to join. I'm comfortable in Agile teams and equally comfortable as the sole resource on a project. I've worked with organisations ranging from early-stage startups to household names including Monster, AVG, and the NHS. The feedback I get most often comes down to the same two things: the work is good, and working with me is straightforward. I think that combination is rarer than it should be, and I try to protect it on every project. If you have something you're building — or something that needs fixing — I'd genuinely like to hear about it. Core tools & technologies: Figma, Vue 3, Nuxt, Quasar, TypeScript, React, AngularJS, Webflow, HTML5, CSS/SCSS, JavaScript (ES6/Vanilla/jQuery), Node, D3, Git — plus the full Adobe suite and wireframing tools across Figma, Balsamiq, Sketch, and Proto.
