I help startups and established companies solve complex technical problems across software architecture, SaaS platforms, cloud systems, APIs, integrations, AI-enabled applications, workflow automation, and learning technology. My work typically includes: • Software and solution architecture • SaaS architecture and scalability reviews • Learning Management System (LMS) development and integration • Learning tools and learning platform integrations • REST API and third-party integration design • Microservices and distributed systems • Cloud architecture and modernization • Technical debt and codebase assessments • Generative AI and LLM integration • AI-powered workflow automation • Backend development with Java and related technologies • Modern web application development with React • Technical leadership, mentoring, and architecture guidance I have extensive experience in the learning technology domain, including working with LMS platforms, learning tools, integrations, and enterprise learning ecosystems. This allows me to contribute not only at the software engineering level, but also with a strong understanding of how learning products and platforms are designed, integrated, and scaled. I’m particularly useful when a team needs someone who can look beyond an individual feature and understand the wider system, identifying architectural risks, simplifying complex designs, improving maintainability, and helping engineering teams make sound long-term technical decisions. I can work either as a hands-on architect/engineer or as a fractional technical advisor for teams that need senior-level architecture expertise without hiring a full-time architect or CTO. If you have an existing SaaS or learning platform that needs an architecture review, an LMS integration, a difficult API integration, an AI feature you want to introduce, or a system that needs to scale more reliably, I’d be happy to discuss the problem and recommend a practical approach. less -
