How I Work
Three ways I build, each backed by projects you can explore below.
Full-Stack Platforms
Enterprise-grade TypeScript apps from system design through deployment: NestJS, GraphQL, REST, and RBAC built for production load.
Mobile Products
Cross-platform apps with real-time sync, OAuth, and store releases: 37+ screens, WebSockets, and EAS CI/CD to iOS and Android.
Cloud & Integration
AWS hosting, CI/CD pipelines, Shopify and third-party API integrations, and middleware that stays reliable under concurrent use.
Focus areas
Languages
Selected Work
Projects across web, mobile, and embedded systems.
Eventure
1,600+ registered users in production
Full-stack event platform built for production scale, not demos. Supports 1,600+ registered users under concurrent load with a NestJS + GraphQL backend, schema design, domain modeling, JWT authentication, RBAC, and a public API structured for future expansion.

Eventure
1,600+ registered users in production
Full-stack event platform built for production scale, not demos. Supports 1,600+ registered users under concurrent load with a NestJS + GraphQL backend, schema design, domain modeling, JWT authentication, RBAC, and a public API structured for future expansion.
Problem: Campus and organizational events needed a reliable platform instead of spreadsheets, with secure roles, registration at scale, and room to grow.
Approach: Architected a NestJS + GraphQL backend from scratch with JWT auth and RBAC. Owned all technical decisions from data model through deployment as a long-lived platform.
