Junior Baez
Full-Stack .NET Developer & QA Specialist

I build software, then I make sure it actually works.

Hey, I'm Junior 👋 — I'm the person who builds it and then makes sure it doesn't break. Based in the Dominican Republic, I split my time between full-stack .NET development and quality assurance, and honestly, I like it that way — building something and stress-testing it teaches you things neither half can teach alone.

about

Two sides of the same discipline.

I work both sides of the software lifecycle. As a Back-End .NET Developer, I build and maintain APIs and authentication systems for a live real estate platform. As a Quality Analyst at Thryv, I audit workflows, coordinate cross-team fixes, and manage CMS content pipelines — experience that's sharpened how I think about edge cases before code ever ships.

That combination is the throughline across everything I build: a Vue-based internal audit tool, a Playwright test framework, a hexagonal-architecture .NET backend, and a native Android app built offline-first for real-world reliability.

Based in the Dominican Republic. Bachelor's in Systems and Computer Engineering, Universidad Católica Nordestana. Fluent in Spanish and English.

Projects that shipped, and were tested doing it.

A cross-section of backend architecture, frontend delivery, QA tooling, and mobile — spanning the full stack I work in.

AInet — Backend

✓ shipped

.NET 9 API built on hexagonal architecture (ports & adapters), separating domain logic from infrastructure for clean testability. JWT auth, Supabase-backed, containerized with Docker, documented via Swagger. Built as Sr. Developer alongside a Tech Lead.

AInet — Frontend

✓ shipped

Companion Next.js 13+ app (app router) styled with TailwindCSS, consuming the AInet API. CI runs formatting and build checks on every push via GitHub Actions; deployed on Vercel.

Dept Hub

✓ in production

Internal tooling hub built for a real SEO department, where quality auditing is the actual job. Includes an Excel Cleaner that auto-filters daily task reports, an Audit Builder with a scored penalty rubric and Word-doc export, and role-based access (Auditor / Supervisor / Admin). This is the project where "developer" and "QA specialist" are the same job.

QA Automation Framework

✓ CI-integrated

A Playwright-based API testing framework with a reusable API client, environment-based config, and Allure reporting. Wired into GitHub Actions so every push and pull request runs the suite automatically. E2E testing scaffolded for future expansion.

LoanManagerDR

✓ solo build

A native Android app for informal lenders and loan collectors in the Dominican Republic — designed offline-first, no backend required. MVVM architecture with Room, BCrypt-hashed credentials, role-based permissions (Owner / Admin / Collector), and full audit logging. Currently redesigning route assignment around an explicit many-to-many client model.
