// what I do

Engineering at the seam of
hardware and software.

⚙️
Mechanical Design
Full-system mechanical design and enclosure architecture. DFM/DFA, manufacturing drawings, fabrication coordination, and hands-on prototyping from machining to 3D printing.
🤖
Automation & Robotics
Designing and deploying automated systems — fluidics, robotic workcells, sensor integration, and motion validation. From concept through installation and documentation.
💻
Software & Integration
Automation software development, code reviews, and hardware-software integration. Comfortable across Python, C/C++, Java, and LabVIEW in engineering environments.

I'm a mechanical engineer with a second degree in computer science from Tufts University (Magna Cum Laude, GPA 3.70). I love working on challenging problems whether that's working on projects that span different disciplines, designing a challenging part, or integrating multiple subsystems.

At Cellino Biotech, I've spent four years designing, deploying, and iterating on automated cell-processing systems — owning everything from CAD and fabrication through vendor management, software integration, and code reviews.

I'm equally comfortable at a machine or a keyboard, and I'm energized by the kind of work that requires both.

Where I've Worked

May 2025 — Present

Mechanical Engineer

Cellino Biotech · Cambridge, MA

Designed mechanical architecture for a next-gen automated cell-processing prototype (~10 integrated subsystems). Contributed to automation software — creating and reviewing PRs, participating in design reviews, and building updates enabling parallel workcell operations.

May 2022 — May 2025

Automation & Mechanical Engineering Intern

Cellino Biotech · Cambridge, MA

Owned the full lifecycle of an automated fluidics system — hardware spec, CAD, software integration, testing, deployment, and documentation. Eliminated manual reagent loading, improving lab throughput and scalability.

June 2021 — August 2022

Mechanical Engineering Intern

Exact Engineering · Needham, MA

Machined, assembled, and tested prototype products for clients across multiple industries. Collaborated directly with customers to develop designs, select materials, and support product realization.

2019 — 2020

Summer Research Intern

Tufts CEEO · Medford, MA

Collaborated with LEGO on SPIKE Prime — integrating third-party sensors and implementing AI/ML algorithms (kNN, linear regression) to support STEM education research.

Let's build something.

I'm open to opportunities in mechanical engineering, robotics, and automation — especially where hardware meets software. If you're working on something interesting, I'd love to hear about it.
