What I'm looking for

I'm looking to build scalable backend platforms where I can apply Java, Spring Boot, Hexagonal architecture, microservices, and disciplined AI-assisted development to complex product and business problems.

At TikTak, I build core backend systems for car rental journeys including checkout, driving, delivery, pricing, payments, and reservations. I design scalable APIs for BFF and operations platforms using Hexagonal architecture.

I integrate AI into development workflows through Spec-Driven Development, Vector RAG, Claude Opus, Grok, and human-reviewed validation. With Graphify, I transformed project dependencies into Graph RAG structures to reduce hallucinations in complex refactoring.

Previously at Etcbase, I developed legal collections systems used by public institutions, banks, highway-payment organizations, and energy companies. I supported workflows spanning legal case organization, notifications, collections, and litigation.

I’ve also built career, utility billing, consultancy, e-commerce, CRM, and ERP platforms from end to end. My work spans Java, Spring Boot, databases, messaging infrastructure, cloud services, and full-stack web development.
