Available to hire
I’m Jonathan, a Senior Software Engineer based in Massachusetts with a passion for building reliable, data-driven mobile apps. I’ve led cross-functional teams through the full software lifecycle, from design to deployment, with a focus on UX, performance, and security across iOS, Android, and web platforms.
I enjoy collaborating with researchers and product teams to turn complex requirements into polished, scalable solutions. When I’m not coding, I mentor junior developers, contribute to open-source projects, and explore new technologies like AI-assisted tooling and IoT integrations.
