Senior People. Real Experience.
Every person on this page has built and shipped production systems for years. Here's the leadership team behind our engagements.
Leadership
Gabrion Stewart
Founder & CEO
15+ years leading platform transformations for Fortune 500 companies and high-growth startups. Gabrion founded Interspark after watching too many companies get stuck between overpriced agencies and underqualified freelancers. He's the person who makes sure the business outcome matches the technical plan.
Jan Feddersen
Founder & CTO
Decades in enterprise software, spanning infrastructure modernization, cloud strategy, and building engineering organizations. Jan's role is making sure every technical decision serves the business, not the other way around. He's the architect clients call when the stakes are highest.
Vladimir Kim
Head of Software Development
Specializes in building performant, maintainable applications for complex business domains. Vladimir's teams build interfaces and systems that scale gracefully and stay clean as requirements evolve.
Stanislav Li
Head of Infrastructure
Deep expertise in cloud-native architectures, container orchestration, and large-scale distributed systems. Stanislav designs infrastructure that's resilient, cost-efficient, and built for the long haul. He's the reason our clients' cloud bills go down, not up.
David Yon
Head of Product Management
David bridges business objectives and technical execution. Across B2B SaaS and enterprise platforms, he ensures every deliverable creates measurable value aligned with client goals.
Shyam Raj
Head of QA
Leads our quality engineering practice. From automated test suites and CI/CD validation to performance benchmarking, Shyam ensures every release meets the bar before it ships. If it's not ready, it doesn't go out.
An Experienced Team Behind the Leadership
Our broader team spans multiple time zones. Every engineer averages 10+ years of professional experience. We staff for judgment and depth, not headcount.
