Website · PPHU Lepsza Energia · 2026
Lepsza Energia: a cinematic story about energy
A marketing site for a renewable-energy company trading since 2003. Most sites in the industry are panel catalogues; this one tells a story as you scroll. Each route is one chapter: sunrise over the solar farm, then storage and energy management, then EV charging and energy communities. The visual reference was premium tech brands such as Apple and Tesla Energy. The mark, three tilted streams of energy that form an 'E', set the colours for every chapter.
- Cinematic scroll narrative
- Next.js static export

- Mark and brand book
- Business cards and social kit

v2project: engineering office for PV, BESS and power systems
A marketing site for a Kraków engineering office that works on photovoltaics, battery storage and power systems. It looks like the tools engineers use every day: a dark screen like CAD after hours, a drafting grid, monospaced labels. The mark is set in type alone, with one accent colour on the digit '2', and the rest of the site is just as sparing.

Our own products
Products we build and run ourselves: web services and apps for Mac and iPhone.
Product · SEO · 2026
PoliczProsto: Polish financial and tax calculators
A portal of Polish financial, tax and business calculators, each on its own landing page built for search. Before we build a calculator, we check Google Suggest to see whether people look for it. Every statutory rate comes from the Dziennik Ustaw and is cited next to the number it feeds. In September 2026 the portal had 58 calculators, with long-form articles and programmatically generated page clusters around them.

BudgetStack: a household budget read from receipts and bank statements
Our own household budgeting app, live since September 2026. A vision model reads receipt photos and PDF e-receipts line by line. Bank statements import in the common Polish formats, and each receipt is matched to the card payment it belongs to. Where the bank shows “Biedronka 187.40”, the app shows butter, coffee and nappies, each in its category, with budgets and a price history per product. A household shares one account with roles, and Postgres row-level security keeps households apart.
- real receipts, all to the grosz
- 145
- rows in one statement import
- 23,752
- Receipt OCR with a vision LLM
- Import of Polish bank formats
- Receipt-to-payment matching
- NestJS + Next.js + BullMQ workers
- Kubernetes on our own servers

StackURL: a link shortener with no database
Our own link shortener, and it keeps no database of links. A trained arithmetic coder compresses the URL and the result becomes the short link, so opening one means decoding it instead of looking it up. Links never expire because nothing is stored. It runs as a hosted service, and a company can run its own white-label instance.
- median ratio
- 0.34
- payload characters
- 24.4
- holdout links
- 37,723
- Arithmetic compression engine
- Model trained on 189k links
- Stateless redirects

- White-label deployment
macOS · Product · 2026
Tilter: a Mac screen that folds as the lid closes
A menu bar app that brings the iPhone Duo fold effect to MacBooks with Apple silicon. As you lower the lid, the screen folds back like a pane of frosted glass and follows the angle of the lid all the way down. Written in Swift and Metal, built and signed without an Xcode project, and translated into nine languages. It is in TestFlight now and will reach the Mac App Store as a free download with a one-time unlock.
- Lid-angle sensor over IOKit HID
- Metal frosted-glass renderer
- StoreKit 2 one-time unlock
- Signing and notarization without Xcode

LabelBite: calories from a photo of the label
A nutrition tracker for iPhone and Apple Watch that runs entirely on the phone. You photograph the nutrition label, pick a portion, and the calories and macros are logged. On-device OCR and Apple's Foundation Models read the label, so there is no backend and no account. It also has widgets, Siri shortcuts, a Live Activity during a meal and Apple Health sync. Still in development.

- SwiftUI + Foundation Models
- Widgets, Siri, Live Activity

TabataTap: an interval timer you can read from across the room
A Tabata and HIIT timer for iPhone and Apple Watch. During a work phase the whole screen turns lime, with a 3-2-1 countdown, haptics and sound, so you know where you are halfway through a burpee. It keeps presets and a workout history with streaks, saves HIIT sessions to Apple Health, shows a Live Activity in the Dynamic Island and runs on its own on the Watch. We are preparing it for the App Store.
- SwiftUI + SwiftData
- Live Activity and Dynamic Island
- Standalone Apple Watch app
- HIIT workouts in Apple Health
AI and automation
Pipelines that read documents, gather data, and take work off people's hands.
AI · Automation
AI OCR & document workflow automation
An internal platform for processing documents. OCR reads each document, AI classifies it and pulls out the data, and the document then goes through the approval workflow. Nobody retypes the same paperwork by hand.
- OCR pipeline
- LLM data extraction
- Workflow automation
- System integrations
Automation · Data
Lead generation & data automation
Pipelines that find leads, collect data at scale and reshape it. Crawlers, ETL jobs and enrichment give sales and analytics current, structured data to work from.
- Lead generation
- ETL & data transformation
- Large-scale data collection
- Data enrichment
AI
AI integrations & automation
We build RAG pipelines, assistants and workflow automation, and we only put them where the gain can be measured.

Engineering budget
Pretty isn't enough.
It has to work.
We combine product thinking, design and software engineering to build things that aren't just beautiful on launch day. They're built to last. Every claim below is a number we agree on before the first line of code.
13years running the studio
20years shipping web code
Fast.
Without it: three seconds to first paint, and half the traffic you paid for never sees the offer.
< 1.8 sLCP on 4G, mid-range phone
Accessible.
Without it: keyboard and screen-reader users are locked out — and in the EU that is now a legal exposure, not a nice-to-have.
WCAG 2.2 AAaudited, zero critical issues
Secure.
Without it: one injected third-party script is enough to read every form your customers fill in.
no unsafe-evalCSP and hardened headers on every route
Scalable.
Without it: the campaign works, the traffic arrives, and the checkout is the thing that falls over.
99.9%monthly availability, p95 TTFB under 200 ms
Maintainable.
Without it: every small change turns into a quote, and you are locked to whoever wrote it first.
