I'm a certified solutions architect for Amazon Web Services with experience in full-stack software development. My typical stack for web development is a React.js front-end paired with a node.js backend hosted on AWS. For mobile development my preferred stack is React-Native but I have experience in native development with Swift for iOS and native Android development in Java. I'd love to help your project at any stage, whether it's UX design, software development, API integration, data migration, or even just bug fixes & documentation. Whether you've got a new idea for an app or need a consult for a redesign on one of your micro-service containers, let me know how I can assist!

I'm a senior software engineer with extensive experience building scalable APIs, cloud platforms, and mobile applications used by billions of users. I’ve worked on production systems at companies like Meta Platforms and T-Mobile, and I bring that same engineering discipline and reliability to every client project. Throughout my career I’ve designed and built backend systems, microservices, and mobile applications that power real products. I specialize in building software that is not only functional but also scalable, maintainable, and ready for long-term growth. In addition to enterprise experience, I’ve also worked extensively with startups and small teams, helping them move quickly from concept to working software. I understand the balance between moving fast and building systems that won’t break as your product grows. Whether you're launching a new product, building an MVP, integrating APIs, or improving an existing platform, I focus on delivering solutions that are reliable, efficient, and designed with best engineering practices. What I Can Help You Build Backend & API Development • REST APIs and microservices • Backend platforms and system architecture • Secure authentication systems (OAuth, Cognito, etc.) • Third-party API integrations • High-performance backend services Cloud & Infrastructure • AWS architecture and deployment • Serverless systems (Lambda, event-driven systems) • Scalable cloud platforms • Database design and optimization • DevOps and deployment pipelines Mobile Applications • Cross-platform mobile apps using Flutter • API integration for mobile apps • Authentication, file uploads, and backend communication • Performance optimization and debugging Technologies I Work With Python • C# • Flutter • REST APIs • AWS • Serverless • PostgreSQL • MongoDB • Microservices • Cloud Architecture • Docker • Event-Driven Systems Recent Types of Projects • Designing backend APIs that support mobile applications • Building serverless cloud systems on AWS • Creating MVP platforms for startups • Integrating complex third-party APIs • Optimizing backend performance and reliability • Debugging and stabilizing production systems Why Clients Work With Me Clients hire me because I bring both enterprise engineering experience and startup speed. I understand how to quickly identify the core problem and deliver solutions that work in production. You can expect: • Clear and professional communication • Clean, maintainable code • Thoughtful system design • Reliable delivery and follow-through I treat every project like a product that will need to scale and evolve over time, not just a quick patch or temporary solution. Education Master’s Degree – Computer Science Bachelor’s Degree – Computer Science If you're looking for an experienced engineer who can help you build, scale, or improve your software, I'd be happy to learn more about your project.
