I help companies design and build applied AI solutions and automation that solve concrete business problems — reliably, pragmatically, and without hype. 🇩🇪 I frequently work with German-speaking companies across DACH (Germany, Austria, Switzerland), and also collaborate with international teams and startups. My focus is on AI systems that work in real-world environments, not demos or hype projects. ⚡ What I Build & Deliver • Applied AI solutions for real business processes • AI prototypes and MVPs to validate ideas fast • Computer vision systems (detection, extraction, measurement) • Document and data extraction from images, PDFs and structured files • AI-driven automation and workflow optimization • Web-based tools and dashboards to make AI usable for teams 🏗️ How I Work • Clear scoping and honest feasibility assessment • Pragmatic solutions instead of over-engineering • Focus on maintainability, data quality and real-world constraints • Transparent communication and structured execution • From prototype to production-ready architecture 🎓 Background I combine a strong academic background in Artificial Intelligence (MSc) with hands-on software engineering experience. I’ve worked on applied AI systems spanning automation, computer vision and machine learning in real operational contexts. 🚀 Have an AI idea you want to validate or bring into production? Let’s discuss your use case and define a clear, realistic next step.

I build production web apps and marketing sites that load fast, look serious, and don't fall over. React + TypeScript on the frontend, Python or Node on the backend, deployed on infrastructure that scales without surprise bills. Background: BSc Software Engineering at TU Wien (Vienna University of Technology). Registered Austrian sole trader since March 2026, operating as Orest Karpiak IT & Electronics. Based in Vienna, working in English, German, Russian, and Ukrainian. ━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT I BUILD Frontend • React 18 + TypeScript + Vite — the modern stack, fast dev loops, fast user loads • Tailwind CSS, custom design systems, no off-the-shelf template look • Fully responsive, accessible, sub-second LCP on real connections • Marketing sites, dashboards, internal tools, SaaS frontends Backend • Python with FastAPI — clean REST APIs, async where it matters, OpenAPI docs out of the box • Node.js / TypeScript when the rest of the stack calls for it • Haskell / Servant when type safety is a hard requirement • PostgreSQL, EdgeDB, Redis, well-designed schemas and migrations Infrastructure • Cloudflare Pages and Workers for static and edge-rendered sites • Hetzner VPS for backends, Docker, systemd, properly configured nginx • Stripe integration for payments and subscriptions • CI/CD with GitHub Actions Quality work the cheap freelancers skip • Real Lighthouse scores, not lies • Structured data markup so you actually rank in local search • Proper error handling, logging, and uptime monitoring • Clean handoff documentation so you (or the next dev) aren't stuck ━━━━━━━━━━━━━━━━━━━━━━━━━ RECENT WEB WORK • Restaurant Wang — single-page marketing site for a 35-year-old Vienna Cantonese/Szechuan restaurant. Hand-written, sub-second load, structured data for local SEO, deployed on Cloudflare Pages. • Rich Witch — landing page for a Vienna avant-garde fashion brand. Dark editorial aesthetic, custom cursor animation, mask-based photo reveals. • My own developer portfolio site. React + TypeScript + Vite + Tailwind, edge-cached on Cloudflare Pages. • Security audits — caught a Parasite SEO / bot-cloaking attack on a client e-commerce site that had been live for months without detection. ━━━━━━━━━━━━━━━━━━━━━━━━━ HOW I WORK • Fixed-scope quotes whenever the work allows. Hourly only for genuinely open-ended exploration. • Direct communication — I flag bad ideas, scope creep, and cases where someone else would serve you better, before they cost you money. • I ship. If I commit to a date, you get it. • Comfortable with both technical clients (founders, engineering teams) and non-technical ones (small business owners, designers, agencies). ━━━━━━━━━━━━━━━━━━━━━━━━━ ALSO IN MY TOOLBOX Beyond web work I design custom electronics — PCBs in KiCad and Altium, ESP32 firmware, IoT devices that talk to a backend. Not many web developers can also build the hardware, and it shows up where it counts: APIs designed by someone who knows what's on the other end of the wire, dashboards built by someone who's actually shipped a sensor. ━━━━━━━━━━━━━━━━━━━━━━━━━ BEST FIT • Marketing sites and landing pages for small-to-medium businesses • SaaS frontends, internal tools, dashboards • API design and backend builds • Performance, SEO, or security audits with concrete deliverables • Cleanup or migration work on neglected codebases • Anything web that touches hardware or IoT Send me your brief. I'll tell you within a day whether I'm the right person, and if I am, you'll get a fixed quote and timeline.
