## About

NinjaDev is a high-performance technical consultancy and "engine room" for venture-backed startups and established enterprises that cannot afford to fail. Founded and led by Jon Gryn, a technical operator and systems architect with over 15 years of experience, the firm specializes in bridging the gap between high-level strategic vision and rigorous, scalable execution. Core Identity - The "Technical Translator"

NinjaDev operates on the principle that the greatest friction in business is the language barrier between leadership and engineering. We act as the Technical Translator, converting ambitious business goals into modular, high-velocity development roadmaps. Whether it is moving a company from "functional chaos" to a design-first sprint culture or architecting a multi-tenant AI ecosystem, NinjaDev provides the elite oversight required to "spike the ball" on complex projects.

Our Core Pillars:

Zero-Compromise Engineering - We build high-stakes systems—from fintech matching engines to compliance-driven healthcare platforms - with a focus on data integrity, security (Google CASA, HIPAA), and long-term scalability.

Fractional CTO & Product Leadership - We don’t just write code; we own the product surface. We provide the leadership necessary to hire, manage, and audit development teams, ensuring every dollar spent translates into a functional, revenue-generating asset.

AI Strategy & Implementation - We architect "Agentic Workflows" and custom Knowledge Bases (using tools like Claude and OpenAI) to automate manual bottlenecks, such as real estate deal summaries or financial underwriting.

Operational Rigor - Drawing from Jonathan’s experience as a licensed Realtor at The Agency (Beverly Hills/Newport Beach) and a PMI-ACP Agile Practitioner, we bring a "luxury service" mindset to the tech world - combining white-glove communication with relentless technical discipline.

NinjaDev doesn't just build software; we build the technical foundations that allow companies to scale
