I build production-ready software end to end - fast, clean, and scalable. Over the last 9+ years I’ve shipped web apps, APIs, cloud services, AI integrations, and game features for startups and enterprises. I lead projects from idea to launch, improve existing codebases, and bring a calm, senior approach to delivery, quality, and communication. **What I built** - Web apps & dashboards (React/Next.js, Angular, Blazor) - APIs & microservices (ASP.NET Core, FastAPI, Node/NestJS) - Real-time systems (SignalR, WebSockets, gRPC) - Cloud & DevOps (Docker, Kubernetes, CI/CD on Azure & AWS) - AI integrations (computer vision, model serving, inference APIs) - Games & interactive sims (Unity, Godot, Phaser engines) **How I work** - Architecture first: SOLID, DDD/CQRS where it fits, modular monolith or microservices. - Quality by default: automated testing, code reviews, clear documentation. - Performance & scalability: profiling, caching, async patterns, cost-aware cloud design. - Transparent delivery: frequent demos, clear milestones, proactive communication. **Core stack** - Frontend: React, Next.js, Angular, Blazor, Vue/Nuxt, HTML/CSS, Tailwind - Backend: ASP.NET Core, Node.js (Express/Nest), Python (FastAPI/Django), Spring Boot - Languages: C#, TypeScript/JavaScript, Python, Java, C++, PHP - Databases: MS SQL Server, PostgreSQL, MySQL, MongoDB, Redis, Firebase - Cloud & DevOps: Azure, AWS, Docker, Kubernetes, CI/CD, Azure DevOps, GitHub Actions - Real-time & messaging: SignalR, gRPC, Socket.IO, RabbitMQ - Desktop & mobile: WPF, .NET MAUI, React Native - Game engines: Unity, Godot, PhaserJS, Unreal Engine If you need a senior engineer who can own delivery, collaborate well with your team, and leave your codebase better than they found it - let’s talk. Share your goals and timeline, and I’ll propose a clear plan to get you there.

Hi, my name is Brett and I've spent the last 5 years working in lifecycle marketing automation as a marketing technology specialist and email developer for several companies. I'm strongest with the marketing automation platform Iterable, but I also have experience with Braze and Emarsys (SAP). I'm great at rebuilding templates (MJML), setting up and testing automations, and working with data feeds and webhooks to integrate 3rd party vendors into workflows/journeys. I take a detail-oriented, trial-and-error type approach to all my work as I strive to deliver great results for my clients. I love working with Postman for journey testing, Litmus for template proofing, and have experience using SQL for audience segmentation. I encourage you to check out my portfolio site at brettwilson.work and reach out if you want to discuss an upcoming project in the martech space. Thanks!
