Case Studies

Maritime crew tax management platform
Maritime · Internal Tools

From spreadsheet chaos to a single source of truth

A maritime operations company managing multiple vessels across international waters came to us with a familiar problem — but an unusually complex version of it. Every month, their team manually reconciled payroll data from separate Excel files for each ship, then cross-referenced each crew member's time in different flag states to calculate tax obligations. Crews moved between vessels. Ships crossed jurisdictions. The spreadsheets multiplied. A process that should take hours was eating days — and one wrong formula could mean a costly compliance error.

  • One-click Excel import — existing payroll files parsed automatically, no re-entry or reformatting
  • Centralised crew & vessel registry — assignments, port locations, and country history in one place
  • Automated tax calculation — liability computed per crew member based on wage periods and jurisdictions
  • Flexible reporting — filterable by crew, ship, country, or date range in seconds

What previously took days of manual reconciliation across dozens of spreadsheets now runs in minutes — with a full audit trail, zero formula risk, and a platform that has been running reliably for several years with minimal intervention.

ADN Pilates website
Wellness · Web Presence

A boutique studio that looks as good online as it does in person

ADN Pilates is a boutique Pilates studio in the heart of Constanta — small groups, high-end equipment, and a distinctly personal approach to movement. When they came to us, the studio experience was exceptional. Their online presence wasn't keeping up. They needed a website that matched the calm, premium feel of their physical space — one that could attract new clients, showcase their classes and equipment, and work in both Romanian and English for local clients and visitors alike.

  • Multi-page site covering classes (Reformer, Cadillac, Spine Corrector, Mat), studio story, testimonials, blog, and contact
  • Live Instagram feed — homepage stays fresh without any manual updates
  • Booking integration with Notino and embedded video to showcase the studio in motion
  • Full bilingual support — separate RO and EN routes, easy for the owner to manage

A digital presence that works as hard as the studio does — attracting new clients organically and giving the brand the credibility it deserves online.

MathWizard mobile game
EdTech · Mobile App In Development

Making maths practice feel like play

MathWizard is a mobile math practice game built for students who find traditional drill-and-repeat learning tedious. The idea: take the core skill-building of math practice and wrap it in a game loop that kids actually want to come back to.

  • Single codebase for iOS and Android — React Native with Expo
  • Firebase backend for authentication, real-time leaderboards, and per-player statistics
  • Multiple game modes, reward system, and a theme engine
  • Monetisation built in from day one — AdMob ads with rewarded video and an in-app purchase to remove ads
React Native Expo Firebase TypeScript AdMob

Currently in late development, targeting release on the App Store and Google Play.

FAQ

What does a fractional CTO do?
A fractional CTO provides part-time senior technical leadership — setting engineering strategy, guiding architecture decisions, hiring and mentoring engineers, and representing technology at the leadership level. You get the same expertise as a full-time CTO at a fraction of the cost and commitment.
When should I hire a fractional CTO?
If your engineering team is growing but lacks senior technical direction, if you are making major technology decisions without a strong technical voice in the room, or if you need a full-time CTO but are not ready for that commitment — a fractional CTO is the right fit.
What is AI software development?
AI software development means building production-grade applications that use large language models (LLMs) and AI APIs as core components — not demos or proof-of-concepts. This includes designing AI-powered workflows, integrating APIs like OpenAI or Anthropic, and building the surrounding infrastructure that makes AI features reliable and maintainable in production.
How much does custom software development cost?
Cost depends on scope, complexity, and timeline. We work on both fixed-price projects and monthly retainers. Every engagement starts with a free discovery call where we scope the work together — you will have a clear estimate before any commitment is made.
What is the difference between a fractional CTO and a consultant?
A consultant typically delivers a report or recommendation and moves on. A fractional CTO takes ongoing responsibility — attending leadership meetings, making decisions, managing engineers, and seeing initiatives through to completion. It is an executive role, not an advisory one.
Do you work with clients outside Romania?
Yes — we work with clients globally. All project communication is in English, and we are experienced with remote collaboration across different time zones.
