Hi — I’m Jason, a Fractional CTO and systems architect who designs and ships large-scale platform capabilities rather than just individual products. I architect config-driven engines, developer tooling, and distribution pipelines that let teams deploy new journeys, rules, and content from configuration rather than code changes. I’ve led as CTO, Regional Tech Lead, and Principal Consultant across insurance, fintech, edtech, and SaaS, guiding cross-border teams and optimizing spend by thousands per month while standardizing architectures used across markets. I’m equally comfortable writing the code, drafting the architecture, and explaining complex ideas to non-technical stakeholders. I’ve built and shipped open scaffolding tools, contributed to open-source projects, and authored technical content for startup founders and CTOs. My approach blends hands-on engineering with strategic leadership to deliver reliable, scalable systems and practical, developer-friendly workflows.
