MARLO
MAYBERRY
Full-Stack Developer — React, TypeScript & .NET

I build and maintain production business systems — leading a Blazor-to-React migration, validating API contracts, reviewing code with merge authority, and troubleshooting CI/CD and integration issues across a four-person team. I also design and ship independent full-stack products, including a browser-based tool with 3,000+ users sustained over two years.

About Me

I'm Marlo Mayberry, a full-stack developer leading a Blazor-to-React migration in production, with code review authority and end-to-end ownership from architecture through delivery.

Experience

EPES Logistics Services

Oct 2023 – Present
Application Developer (.NET / React)
  • Leading a Blazor-to-React migration as the sole frontend developer on a four-person team, rebuilding a production logistics platform used for 4PL shipping quote, tracking, and document workflows
  • Review pull requests with merge authority across the team, validating API contracts, flagging dependency and architecture risks, and using AI-assisted code review to raise the quality bar on production changes
  • Architecting reusable React component systems and migrating state-heavy Blazor workflows to React with full API integration and form validation
  • Troubleshoot CI/CD pipeline failures, deployment issues, and environment and service connectivity problems across the migration
  • Built and maintained multi-step operational workflows in Blazor including rate quoting, multi-stop shipment handling, document management, and shipment history
  • Supported secure session handling through Redis-backed persistence, cookie lifecycle updates, and authentication gate enforcement across protected routes
  • Contributed to MVP planning and application structure while expanding release reliability through automated frontend testing

DBMG

Oct 2022 – Aug 2023
Developer, QA Automation
  • Built QA systems and automated build verification testing to support reliable release pipelines
  • Wrote automated regression tests using Selenium WebDriver (C#) and GREP-based log verification
  • Reduced manual QA bottlenecks, improving release confidence across the team

Technical Expertise

The core tools and frameworks I use to build production web applications.

.NET / Blazor Systems

.NET 8, Blazor Server, and C# powering production business systems — quoting, tracking, and document workflows for a 4PL logistics platform.

React + TypeScript

React, TypeScript, and Vite for component-driven UIs. I build fast, type-safe front-ends for web applications and side projects.

API Integration & Contracts

REST API integration, contract validation, and frontend/backend coordination — plus client-side state management and persistence across Blazor and React.

Testing / QA Automation

Automated build verification and regression testing using Selenium WebDriver (C#). I've owned QA pipelines that ship code with confidence.

UI/UX

Responsive layouts, accessibility basics, and form-heavy workflow design. HTML, CSS, Tailwind, and Bootstrap — I embrace the front-end.

DevOps / Delivery

GitHub Actions for CI/CD, Netlify and Azure deploys, and hands-on troubleshooting of pipeline failures, deployment issues, and environment and service connectivity problems.

Systems I Work With

The technical environments and architectural concerns I navigate day-to-day in production development.

Cross-System Integration

Coordinating work across Blazor and React front ends, .NET APIs, and shared business logic — keeping quoting, tracking, and document workflows consistent as the platform migrates piece by piece.

Contract Integrity

Validating API contracts between frontend and backend, catching breaking changes before they ship, and keeping request/response shapes honest as endpoints evolve.

Technical Investigation

Tracing CI failures, deployment issues, environment misconfiguration, and service connectivity problems back to root cause — not just the frontend symptom.

Automated Testing & Release Reliability

Push-based automated front-end testing, regression coverage, and QA pipelines designed to keep production deployments stable.

Azure & GitHub-Based Delivery

CI/CD workflows using GitHub Actions, Azure hosting, and Netlify deploys for consistent, repeatable release pipelines.

Modular UI Architecture

Reusable Razor component systems, client-side tool modules, and local-first persistence patterns built for long-term feature expansion.

Code Review & Quality Ownership

Reviewing pull requests with merge authority, flagging architectural concerns and dependency risks before they land, and using AI-assisted review to raise the quality bar on production changes.

Architecture & Dependency Analysis

Evaluating new dependencies and architectural tradeoffs, weighing long-term maintainability against short-term velocity for a platform in active migration.

Things I've Built

These are the products I actively maintain today, spanning production UI architecture, client-side tooling, and full-stack application design.

Worldbinder

Multi-tenant, permission-aware campaign encyclopedia and continuity manager for tabletop RPGs — full-stack SaaS with field-level authorization, wiki-linked entities, and audit history.

Worldbinder

Permission-aware campaign continuity platform for TTRPGs — multi-tenant SaaS with entity relationships, revision history, and campaign-scoped authorization. Live on Railway.

Ledgerly

Full-stack financial planning platform with clean layered architecture, debt projection, scenario comparison, budgeting, exports, and production deployment on Railway.

Ledgerly

Privacy-first financial planning platform with debt payoff simulation, scenario comparison, budgeting, exports, and credit projection — shipped as a full-stack product on Railway.

The DM's Toolbox

Browser-based tabletop RPG suite: initiative tracking, a lightweight battle map VTT, character management, encounter building, and a Notion-style campaign journal — all local-first and offline-capable.

The DM's Toolbox

Modular browser-based tabletop toolkit — initiative tracking, battle map VTT, and campaign journaling with local-first persistence.

PDF Workbench

Client-side PDF toolkit: view, merge, split, edit pages, convert images, compress, and sign — no file uploads. Eight independently-scoped tools sharing a modular client-side architecture.

PDF Workbench

Privacy-first PDF toolkit: view, merge, split, sign, convert, and compress — entirely client-side, no uploads, no backend.

Experiments

Smaller experiments and UI prototypes. Older work; included for completeness.
