Justin Dosio

Customer Engineer and Implementation Specialist in New York

<H1>Hello World!</H1>

Nice to greet you, I'm Justin!

Originally from New York and now based in Valencia, Spain, I’m a technical implementation and operations professional passionate about creating seamless, resilient, and user-centered product experiences. With a background spanning fintech and SaaS—including roles at Modern Treasury, AutoFi, and Chili Piper—I’ve led complex integrations, optimized API workflows, and helped elevate the quality of tools that developers and teams rely on every day.

I operate at the intersection of product, engineering, and customer success, translating technical complexity into scalable, maintainable, and intuitive solutions. Whether configuring payment systems, troubleshooting intricate API behaviors, or collaborating cross-functionally to improve user journeys, I approach every challenge with a systems-thinking mindset and a bias toward clarity and simplicity.

Relocating to Spain has deepened my appreciation for global collaboration and adaptability—skills I bring to every project. I’m known for proactive problem-solving, strong documentation practices, and a keen attention to detail, all while staying focused on the real humans behind the product.

Let’s build something that just works—and works beautifully.
