Information Science • Offshore Survey • Search & Rescue • Marine Tech

Hi, I’m Sebastian Downes.

I’m an information science student with hands-on experience in offshore survey, marine technology, and search and rescue workflows. I work with undersea systems, field operations, and data-driven tools that help turn difficult marine conditions into useful information. Outside of work and school, I’m an avid skier, and hit the slopes every chance I get.

About

What I’m about

I combine technical problem-solving with field operations experience. In offshore survey and search & rescue settings, I’ve worked with undersea systems, data processing, and cross-functional teams under time pressure. I integrate approaches I have learned here into data science applications utilizing modern tools to understand complex data.

I’m drawn to roles where careful execution matters: turning messy field conditions into clean, trustworthy data.

Projects

A few projects from the water and the keyboard: how I build, test, and learn.

Capstone (In Progress): ISchool Career Dashboard

Goal: Create a web dashboard for informatics undergraduate students at the University of Washington to connect them with resources, aid in choosing classes, and offer a go-to place for common questions and concerns.

JavaScript Firebase Prototyping User testing

My role (backend)

I built the backend in JavaScript with Firebase, set up deployment, and handled ongoing maintenance so the team could test a stable build. I also participated in outreach conversations with clients/testers and brought those requirements back into implementation.

Problem / opportunity

Create a clearer path for Informatics students who know they need career guidance but do not always know where to start.

Process

As a team, we started with an initial prototype, built a quick “example” version to validate the concept, then did client outreach to recruit testers. We ran research + user testing, synthesized feedback, and are now iterating toward the final product.

Outcome

Built and deployed a working prototype that the team could test with students and use to guide final product decisions.

Takeaways and Next steps

Most user testing was centered around which resources were most lacking in the current infrastructure. Overwhelmingly, the takeaway was that many students are not aware of resources at their disposal including counseling and curriculum options, meaning our initial prototype was already proving to be useful. Our next steps are to finish the refined prototype, tighten the flow through the tool based on the latest user sticking point findings, and prepare a polished final build for handoff/demo.

Integrating undersea instruments into a search & rescue workflow

Goal: fuse instruments into a reliable positioning workflow for seabed operations that is accurate, repeatable, field-ready.

Python Binary parsing Integration Field-ready testing

My role

Instrument integration and translation of binary data using Python.

Problem / opportunity

Small undersea assets are notoriously hard to position; solving this made our work faster and more confident offshore.

Process

Documentation → lab testing → iterative validation cycles until the workflow was stable and correct.

Outcome

Produced a stable positioning workflow that reduced uncertainty during field operations and allowed the team to use small undersea assets more confidently.

Takeaway

Adequate time allocation reduces stress and increases overall execution efficiency.

Vessel search (under NDA)

Goal: locate a small vessel off the coast of Australia after earlier search passes came up empty.

Technical leadership Operations Data processing Team coordination

My role

Technical lead: equipment operation and maintenance, data processing, and field responsibilities.

Approach

Sectioned areas by likelihood and searched methodically until successful.

Outcome

The vessel was found.

Takeaway

How to collaborate with diverse teams under high stress and away from support.

Details and media: coming soon (NDA).
