What I'm looking for

I'm looking to build secure, product-focused web, mobile, desktop, and backend systems where I can own architecture through deployment, solve real operational problems, and apply strong authorization, auditability, and secure-development practices.

I've built the NovaBank fintech wallet MVP with Go services, KYC workflows, role-based administration, auditable payment flows, and defense-in-depth security controls. I also develop production systems for The Web Is Mine, including DealerLink/CarGrid marketplace and vehicle-inventory workflows with dashboards, subscriptions, invoices, and CSV/FTP/SFTP synchronization.

I take projects from requirements and architecture through database design, implementation, integration, debugging, deployment, and client handover. My work spans Go, Node.js, React, Next.js, React Native, desktop applications, PostgreSQL, cloud storage, secure authentication, authorization, and OWASP-aware delivery.
