At Amberscript, I own billing, pricing, and subscription systems across Java/Spring Boot and React, including Stripe payments, invoicing, and subscription management. I also designed and built a pricing engine from scratch.
I’ve integrated AI/LLM providers into product features and built a subtitle validation microservice with message-queue integration and an LLM-assisted validation step. My work also includes enterprise authentication and automated file-retention systems.
At CCBILL, I contributed to a secure online credit card payment system handling real-money currency conversion. I modernized the application, added features, wrote transaction tests, and built a stub service for safe pre-release testing.
At Devoteam, I delivered integration projects for healthcare, e-commerce, and HR clients, connecting platforms such as SmartRecruiters, Workday, Whoz, and Google. In a solo project, I built a language school management platform end-to-end with Next.js, TypeScript, Prisma, and Supabase.
