License Plate Capture
Problem
Critical supplier plate capture and validation module on a legacy stack (.NET Core 2.1 / Angular 7), with irregular response times and growing technical debt.
Decision
Incremental modernization to .NET 8 and React 19, optimizing queries, stored procedures, and API contracts without interrupting operations.
Impact
Better stability and maintainability, with more consistent response times under volume.
Critical Case Management
Problem
End-to-end critical case management on a Java backend that was hard to evolve, with business rules and workflows that could not break.
Decision
Backend rewrite in Node.js preserving business rules, roles, and validations, refreshing the stack without losing functional compatibility.
Impact
Full technology refresh while keeping the critical workflows and custom reporting intact.
Personal
Savings Planner
Problem
Planning personal savings across two currencies with a moving exchange rate makes manual calculation error-prone.
Decision
Financial rules and data concentrated in the business logic layer, connected to a live USD exchange API, with chart-based tracking.
Impact
Mixed-currency savings plans with reliable math and visual tracking.
Camelia Cafe
Problem
A cafe checkout needs to charge fast, in few steps, on limited hardware and in continuous use.
Decision
Minimal checkout app optimized for daily operations, iterated with real feedback from the counter.
Impact
Frictionless daily operations: sales, totals, and closures.
