👋 Hi, I’m a .NET Software Architect with nearly 10 years of experience designing scalable, high-performance systems. I specialize in microservices architecture, system modernization, and cloud-based solutions. I lead the design and development of scalable .NET solutions, ensuring alignment with business goals and modern tech trends. My focus is on performance optimization, seamless system integration, and enhancing maintainability. I also enjoy mentoring teams and driving innovation. Let’s build something great together! 🚀
Full-stack software craftsman and technical leader with over 15 years of experience. Equally adept at system design, programming, technical leadership, mentorship, and business collaboration. Have a wide breadth of technical experience, but specialize in backend API development, relational databases, and web applications. Passionate about simplicity and efficiency. I have worked at over a dozen companies large and small, in a handful of different domains. Also participated in hundreds of interviews, about half-and-half as the interviewer and the interviewee. I have given dozens of talks and training sessions on a variety of topics, mostly focusing on distributed systems, caching, and testing. My top skills are Java, SQL, testing, and refactoring.

With 13+ years in the HighTech industry, including 9 years in FinTech, I specialize in building scalable, high-performance backend systems for eCommerce and financial platforms. My expertise lies in Java, Spring Boot, Microservices, Domain-Driven Design (DDD), and Relational Databases, ensuring businesses have reliable, efficient, and secure infrastructures. Beyond my technical role, I am passionate about mentorship and community impact. I led a Backend Guild, fostering knowledge sharing and best practices across engineering teams. I also co-managed the Tech-Blogging Program at Baot, helping women in tech publish their first technical articles, and served as an Intuit Women’s Network ERG Leader, advocating for career growth and inclusion in tech. Over the years, I played a pivotal role in architectural transformations and financial integrations, including: ✅**Hybrid SDK for Sensitive Data Detection (Intuit)** – Designed a Hybrid SDK that enabled dynamic configuration updates without requiring SDK version upgrades. Extracted validation logic from the SDK and represented it as mathematical expressions. This approach was secured through a patented method: Secure, Dynamically Loaded Input Validation Using Mathematical Expressions. ✅ **Monolith to Microservices Transition (Behalf)** – Led the company’s first microservice transition, mentored other teams, and introduced an Anti-Corruption Layer (ACL) to bridge legacy dependencies and ensure a smooth migration. ✅ **Wells Fargo Integration** – Engineered a seamless connection to enhance payment processing. ✅ **Cross River Bank & PPP Integration** – Led the integration efforts during the pandemic, enabling SMBs to access critical funding through the Paycheck Protection Program (PPP). Now, as a freelance backend engineer, consultant, and mentor, I help businesses architect scalable eCommerce platforms, optimize payment flows, and build robust backend infrastructures tailored to their needs. 💡 What I Offer:🔹 **Backend Development** – Scalable, high-performance Java & Spring Boot applications. 🔹 **Consulting & Mentorship** – Guiding teams on architecture, best practices, and code quality. 🔹 **Code Reviews** – Ensuring clean, efficient, and maintainable codebases. 🔹 **Public Speaking & Thought Leadership** – Sharing insights on backend development, FinTech, and eCommerce. Let’s connect! Whether you need backend expertise, consulting, or mentorship, I’m happy to help. 🚀
