I’m a Senior Full-Stack AI Engineer with 9+ years of experience building and owning production web applications and business platforms end to end—from MySQL data models and secure .NET REST APIs to responsive SPA frontends in Angular. I focus on scalable backend architecture, reliable database design, performance optimization, and clean, secure application practices (authentication/authorization, role-based access control, and API security). I’ve worked across SaaS and financial services environments, helping teams automate reconciliation and document-processing workflows by integrating AI/ML services into production systems. Recently, I developed the Numasync Accounting Assistant platform with scalable services and secure integrations for enterprise banking operations, and earlier I contributed to cloud-based B2B SaaS products involving procurement, inventory, purchasing, and POS integrations while collaborating closely with QA and product stakeholders through Agile delivery.
