O mnie
Senior software engineer and solutions architect with 16+ years building systems in finance, insurance, telecom, energy and media. I specialise in .NET (C#, ASP.NET MVC/Core, .NET 8), SQL Server, Azure and application security. Based in Warsaw, I run Enneal – delivering custom software, vulnerability remediation and products.
How I help: • Custom software – web apps, REST APIs, multi-tenant systems, ERP integrations (SAP S/4HANA, TOTVS), legacy upgrades. • Application security – SAST/DAST/SCA triage, fixing vulnerable code (OWASP Top 10), threat modeling, OAuth2/OIDC, security headers, tenant data isolation, PII-free logging. • Enneal products – POS, LIMS, martial-arts schools.
Track record: led vulnerability remediation for financial systems at Ebix Latin America (35% fewer vulnerabilities); integrated OutSystems with SAP S/4HANA on a financial project.
How I work: scope, milestones, tests and hand-over documentation. English (fluent) and Portuguese (native); basic Polish and Spanish.
