With over 20 years of experience at the intersection of high-scale software engineering and operational business management, I offer a unique blend of technical mastery and entrepreneurial grit. I specialize in building resilient, scalable systems and optimizing business processes through intelligent automation. Core Technical Strengths I am a hands-on technical leader with deep expertise in modern architectural patterns. My approach focuses on creating maintainable, testable, and high-performance software. Software Architecture: Expert-level implementation of Clean Architecture, CQRS, and MediatR. I design systems that decouple business logic from infrastructure, ensuring long-term agility. Engineering Leadership: Proven track record as a Head of Engineering and Software Engineering Manager, leading cross-functional teams to deliver complex products on tight timelines. Full-Stack Development: Extensive experience across the stack, with a focus on robust backend systems and cloud-native environments. Business & Operations Expertise Beyond the code, I am a seasoned business owner with a background in physical facility management and digital marketing. Business Automation & CRM: Advanced proficiency in GoHighLevel, including A2P 10DLC compliance, lead generation workflows, and CRM architecture. I help businesses turn manual tasks into automated revenue streams. Operational Management: Experienced in the full lifecycle of business ownership—from acquisition and financial modeling to brand development and capital improvement projects. Strategic Marketing: Skilled in developing "rugged" brand identities, high-conversion cold-calling scripts, and physician-led wellness program marketing. Professional Experience Highlights Engineering Leadership: 15+ years driving technical strategy, mentoring engineers, and refining SDLC processes for high-growth firms. Business Owner & Operator: Successfully managing multi-location fitness facilities, overseeing everything from facility maintenance and equipment procurement to member retention and financial scaling. Real Estate & Investment Analysis: Adept at evaluating complex data sets, such as rent-to-price ratios and cash-flow potential, to drive investment decisions. What I Deliver as a Freelancer I don’t just write code; I solve business problems. Whether you need a System Architect to overhaul your backend, a Business Consultant to automate your sales funnel, or a Technical Lead to bridge the gap between business goals and engineering execution, I bring a disciplined, "hardcore" work ethic to every project. Let’s build something built to last.
