🚀 Tech Lead & Full-Stack Engineer building large-scale e-Government and university platforms.
I lead the design of Onegate single-window portals, Student & University Service Portals,
and centralized SSO / identity systems — shipped to government agencies and
universities across Vietnam.

• React Hook Form 7 + Zod 4, NextAuth 5 (Credentials · Google · Keycloak PKCE)
• next-intl 4 (multi-locale), Zustand 5 + nuqs, AG Grid 35, ECharts / Recharts
• Real-time via SignalR, Redis caching, Winston logging

Backend

• .NET 9 microservices in Clean Architecture (Application · Domain · Infrastructure · Web)
• CQRS with source-generated Mediator, Minimal API endpoints, API versioning, NSwag/OpenAPI
• EF Core across SQL Server · PostgreSQL (pgvector) · MongoDB, plus Dapper & bulk operations
• Keycloak authn/authz (AuthServices SDK · UMA), Duende token management, OIDC, JWT, Argon2
• Messaging & jobs: RabbitMQ · Kafka (KafkaFlow) · MassTransit · Hangfire, Avro serialization
• SignalR (Redis backplane + MessagePack), Elasticsearch + Serilog, Polly resilience
• Mapster / Mapperly, FluentValidation, document generation (OpenXML · PDF · QR/barcodes), MailKit

Domains

• 🏛️ Onegate — single-window public administration portals ("Một cửa") & online public services (DVCTT)
• 🎓 University Information System (UIS) — student & university service portals deployed for universities nationwide
• 🪪 eCitizen — citizen services and digital identity
• 🔐 Centralized SSO / identity & access management (Keycloak, UMA)

"Why do we say there are plenty of fish in the sea, when their population declines every year?"

Products I led / built, live at universities across Vietnam:

Onegate (single-window portal) — deployed at: HCMUE · HVNH · Thang Long · HCMULAW · UEL

SSO / Identity (Keycloak-based) — deployed at: QNU · UEL · HVNH · DLU

• Building a modern Keycloak-based SSO client on Next.js 16 + React 19
• Leading frontend architecture for Onegate and university service portals
