Real systems highlighting architectural decisions, technical trade-offs, and measurable outcomes.
Enterprise Banking System & Approval Workflows
Multi-module enterprise core banking platform developed at FPT IS
Complex banking business modules required strict multi-level approval logic, standardized data mapping, file imports, and efficient error handling without sacrificing query performance.
Developed modular Spring Boot microservices with Jmix (Vaadin) framework UI integration, optimized PostgreSQL queries using JPA/Hibernate, and enforced OpenAPI specifications.
Stock Watch Platform — Microservices & Real-Time Streaming
Event-driven real-time stock monitoring architecture with Kafka & Keycloak
High-frequency price feed updates flooded primary databases and delayed user notifications during volatile market periods.
Architected separate API and data microservices using Spring Boot, streaming price updates with Apache Kafka, caching active ticks in Redis, and pushing updates via WebSockets.
