About
Founder & Technical Lead
With 15+ years leading engineering and product teams at companies including Criteo, the founder has managed teams of 70+ engineers, driven double-digit revenue growth, and delivered complex software at scale. Smart Lazu Software brings that senior-level experience directly to clients who need it — without the overhead of a full-time executive hire.
Our Work
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.
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 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.
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 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.
Currently in late development, targeting release on the App Store and Google Play.
