I am a Senior Backend Engineer and Software Architect with 20+ years of experience designing, building, and maintaining production-ready backend systems, distributed architectures, APIs, and microservices. My core stack includes Java, Spring Boot, Node.js, PostgreSQL, AWS, Docker, CI/CD, REST APIs, and event-driven systems. I also use AI-assisted software engineering workflows with LLM-based tools such as ChatGPT, Claude, and Gemini to accelerate code analysis, documentation, troubleshooting, optimization, and technical research, while maintaining full ownership of architecture decisions, implementation, testing, code quality, and delivery. In recent years, I have worked on high-impact backend platforms across sports-tech and fintech/payment systems, including real-time payment integrations, FedNow, RTP, ACH, ISO 20022, scheduling, notifications, memberships, payment workflows, and complex business logic. I focus on reliability, performance, maintainability, clean architecture, and solving backend problems with a hands-on engineering approach. I am open to remote opportunities as a Senior Backend Engineer, Software Architect, or hands-on Tech Lead, where I can contribute to backend architecture, system design, technical delivery, scalable product development, and pragmatic AI-assisted engineering practices.

Cultural Fit Analysis
The candidate has a diverse project background, ranging from automotive and banking to geographic information systems, indicating adaptability to various industry contexts. While the experience is primarily in traditional backend and enterprise systems, the ongoing Master of Blockchain Engineering and recent roles involving payment systems show a clear pivot towards the target role. The breadth of skills, including various programming languages (Java, Node.js, Go, Groovy, PHP, Ruby) and database technologies, suggests a versatile and continuous learning mindset. However, direct experience with decentralized technologies or specific blockchain protocols is not explicitly detailed in the past work experience, which might require a cultural adjustment to the blockchain-specific development paradigms.
Soft Skills & Operational Fit
The candidate's experience as a Lead Software Architect and Project Coordinator suggests strong leadership, team coordination, and project management skills. Their involvement in agile scrum methodologies and collaboration in remote environments indicates good operational fit for structured development processes. The use of AI-assisted development workflows highlights an adaptive and efficient approach to problem-solving.
