Engineering Profile

Software developer with 10 years of experience building and delivering enterprise web, desktop, and mobile applications using Angular and .NET. I've worked on large-scale systems for U.S. clients in healthcare and highway tolling, as well as internal enterprise platforms such as work and resource management systems.

My focus is on improving performance, build speed, and application stability while working on architecture decomposition and debugging complex issues across multiple environments. I regularly lead project kick-offs, estimate work, implement and test features, and guide development teams to ensure high code quality and timely delivery.

Featured Engineering Challenges

Real technical problems solved and lessons learned

Real-Time

Real-Time UI Synchronization

Problem
Users needed to see updates in real time without refreshing the page. Multiple users working simultaneously required instant synchronization across all connected clients.
Solution
Implemented reactive UI updates using SignalR and RxJS streams so changes propagate instantly. Built observable streams that listen for server events and automatically update the UI state.
Angular RxJS SignalR
Performance

High-Performance Data Grid Rendering

Problem
Large enterprise datasets caused significant UI lag and slow rendering times. Users experienced freezing when loading thousands of rows in data grids.
Solution
Optimized Angular change detection strategies, implemented virtual scrolling, and refined data loading patterns. Configured DevExtreme grids to handle thousands of rows efficiently with lazy loading.
Angular DevExtreme TypeScript
Architecture

Multi-Tenant Board Architecture

Problem
Application needed to support multiple tenants with boards and cards while keeping data isolated and scalable. Required efficient data fetching without compromising security or performance.
Solution
Designed a scalable frontend architecture with proper data isolation patterns. Optimized API interactions using caching strategies and efficient state management to minimize network requests.
Angular .NET APIs Microservices
Debugging

Production Bug Investigation

Problem
Customer-reported issues that were difficult to reproduce in local development environments. Intermittent bugs occurring only under specific production conditions.
Solution
Analyzed application logs, network requests, and error traces to identify patterns. Reproduced edge cases locally and traced issues across frontend and backend systems to pinpoint root causes.
