Material Folder Icons

A Visual Studio extension that makes large .NET solutions easier to scan without fighting the IDE.

The extension discovers and resolves a 377-pair icon catalogue, registers image resources lazily, and integrates through supported CPS and hierarchy APIs. Unsafe writes are rolled back and quarantined instead of leaving Solution Explorer in an uncertain state.

  • Case-insensitive resolution with canonical resource keys
  • Defensive fallback, rollback, and hierarchy isolation
  • Asset generation pipeline plus a deterministic verification harness

Commerce Architecture

An opinionated .NET commerce foundation built to keep domain rules, transport, and infrastructure clearly separated.

A GraphQL gateway calls service-owned gRPC contracts while Catalog protects product and inventory invariants through aggregates, value objects, and domain events. Application errors travel across gRPC metadata and surface as consistent GraphQL errors.

  • Service boundaries with Clean Architecture and DDD
  • GraphQL edge API with generated gRPC clients
  • Typed result flow from domain to transport

Bondy

A service-oriented social platform foundation focused on identity, secure access, and dependable asynchronous work.

The public backend separates gateway, identity, and mail responsibilities. It combines OAuth2 and JWT flows with PostgreSQL persistence, service health endpoints, Docker orchestration, and a deduplicated outbox worker for email delivery.

  • Gateway-authenticated service boundary
  • OAuth2, JWT, API keys, OTP, and role-aware access
  • Background outbox dispatch with retry-aware state

TechGear

A full commerce flow for computer hardware, spanning a Flutter client and five ASP.NET Core services.

Authentication, catalogue, users, orders, and chat sit behind an Ocelot gateway. The product covers carts, checkout, coupons, loyalty, order tracking, and authenticated WebSocket conversations across mobile and web clients.

  • Five-service backend behind an API gateway
  • JWT-secured workflows and real-time chat
  • Flutter client with protected local credentials

Restaurant Workflow

A role-based ordering system that connects front-of-house, kitchen, and payment workflows.

An Angular client works through an Ocelot gateway to dedicated order and payment services. The backend models tables, menu availability, kitchen status transitions, refresh-token authentication, reporting, and scheduled order-timeout handling.

  • Operational state from table entry to payment
  • Separate order and payment service boundaries
  • Scheduled timeout processing and date-based reporting

NO RATINGS / EVIDENCE OVER PERCENTAGES
01 / 06

Backend

The centre of gravity: explicit business rules, dependable APIs, and asynchronous work.

02 / 06

Frontend

Product surfaces for operational systems, mobile workflows, and public-facing experiences.

03 / 06

Data

Relational modelling first, with focused caching and vector capabilities where the system needs them.

04 / 06

Architecture

Boundaries and delivery patterns chosen to make changing business rules safer.

05 / 06

DevOps

Practical ownership from a working service to a repeatable, observable deployment.

06 / 06

Tooling

The development environment is part of the product: automate checks and make the system legible.

CURRENT FOCUS

Applied publicly.
Going deeper.

01DDD

Richer aggregate boundaries and domain event modelling

02gRPC

Service-owned contracts and transport-safe error flow

03GraphQL

Gateway composition over independently owned services

04VS Extensibility

Deeper CPS, hierarchy, and image-service integration

(03)EXPERIENCE

From feature delivery to system ownership.

Portrait of Truong Le Duc ViHO CHI MINH CITY / VN

Fullstack by range. Backend at the centre. I care about software that stays understandable as the business around it changes.

01 / PATH

I graduated in Software Engineering from Ton Duc Thang University in 2026. Since then, my work has moved from real-time backend integrations into full ownership of enterprise workflows spanning HR, sales, and accounting.

02 / PRACTICE

I enjoy the point where product rules become technical structure: deciding what belongs in a domain model, what should happen asynchronously, and what an interface needs to reveal so a system feels understandable.
