01 / Focus
Reliable software startswith strong foundations.
I focus on backend engineering that stays scalable, testable, and understandable as products and teams grow.
Java / Spring Boot
API development
REST and SOAP integrations with thoughtful validation, clear contracts, and dependable data flows.
Software quality
Unit and integration testing that protects behavior, improves confidence, and supports reliable delivery.
Agile delivery
Effective collaboration in multinational Scrum teams, from requirement analysis through implementation and refinement.
Code lives in systems.
Systems live in context.
02 / Selected project
Receipts in.Friendships intact.
Try SplitlySplitly turns a crumpled receipt and six different memories of dinner into one calm answer: who owes whom, and exactly how much.
The origin story
A weekend trip. Seven friends. Six paying. One person being treated. Several currencies. And one group chat slowly becoming an accounting department.
So I built the tool we actually needed — precise enough for the awkward cents, simple enough to use before the next round arrives.
Receipt goes brrr.
Upload a photo and local OCR + vision extract the merchant, date, currency, products and total. Everything stays editable, because receipts enjoy chaos.
Math, but social.
Split an item equally or by quantity, let the group cover a friend, and record one bill paid by several people.
Three transfers. Done.
Every item becomes a detailed personal balance, then Splitly reduces the final payback to the shortest practical list.
