Full-stack engineering
TypeScript, Go, Python. End-to-end ownership from schema to shipped product. Comfortable as the only engineer or as a senior IC in a larger team.

that last.
Software engineer with a decade of building production systems and a parallel track running cross-functional student teams at university. I care about clarity, momentum, and shipping things that hold up.

01 / ABOUT
Engineer first. Operator by training.
PHOTO
I write code for the same reason I ran a 14-person student council: I like turning ambiguous goals into shipped things. Most of my work sits at the intersection of backend systems, developer tooling, and the messy human coordination that makes either of them succeed.
Before going independent I led platform teams across two startups and chaired the technical faculty's student board for three terms. The pattern is consistent — small groups, real ownership, fewer meetings.

What I do.
Four shapes of engagement. Pick one, or mix — most clients start with a review and decide from there.

■
Technical leadership
Fractional engineering management and tech lead engagements. Hiring loops, architectural review, on-call hygiene, postmortems that change behavior.
03
■
Platform & DX
Internal tooling, CI pipelines, codebase migrations, and the unglamorous infrastructure that makes a team three times faster.
04
■
Code & architecture review
Independent reviews of codebases, designs, and team practices. Written report, ranked findings, and an actionable plan.
