WORK EXPERIENCE
BeomyTech (Canada / Israel) – Senior Full-Stack / Backend Engineer 03.2024 – Present
FinTech / RetailTech / FoodTech Enterprise CRM & POS Ecosystem
• Architected a polyglot microservices system using Golang and gRPC to build a high-performance self-service
checkout engine, achieving sub-20ms transaction processing speeds.
• Implemented an asynchronous event-driven document processing and financial reporting pipeline via NestJS
and RabbitMQ, reducing peak PostgreSQL database load by 65%.
• Designed a scalable retail CRM module for loyalty programs backed by TypeScript, TypeORM, and secure
identity management through Auth0 (SSO/RBAC).
• Developed a highly responsive React & TypeScript user interface for self-service kiosks, optimizing component
rendering (Virtual DOM) to handle instantaneous peripheral barcode scans.
• Engineered secure, idempotent integration modules connecting with banking terminals and automated third-
party fiscal state services (E-Invoicing/PRRO), completely eliminating duplicate transactions.
