ROLEFull-Stack Developer
STATUS● ONLINE
I build end-to-end web products: the interface, the API, the data layer, and the boring glue between them. A decade of shipping software for startups that needed to move fast without leaving a mess behind. I ramp quickly on unfamiliar stacks, plug into teams with minimal overhead, and tend to be the person who gets handed the tangled codebase, to refactor it or migrate it off entirely.

// 01 ABOUT / BIO

An engineer who / cares about
the / seams.

I'm Genesis, a full-stack developer who's happiest bridging a crisp interface with the systems behind it.

I started on the frontend, chasing pixels, then followed the data down into databases, queues, and infra because I got tired of handing off specs and hoping. Today I build product end-to-end, ramp fast on unfamiliar stacks, and work best with small teams that don't have time to hand-hold.

A lot of my work is refactoring and modernization: inheriting a tangled codebase, untangling it in public, and when it's worth it, migrating it to a stack that can carry the next year of growth. Upgrades, CI/CD pipelines that actually ship, and the unglamorous glue nobody else wants to touch.

// 02 SERVICES / CAPABILITIES

What I / do,
end-to-end.

[SVC.01]

End-to-end product

From empty repo to production. React on the front, Node + Postgres behind it, CI/CD that actually passes.

React React Native Vue Nuxt Node Docker AWS
[SVC.02]

API & data layer

REST and GraphQL APIs, schemas that age well, query patterns that don't fold at scale.

Python Django GraphQL Postgres MySQL Redis
[SVC.03]

Rescue & refactor

Inherit a gnarly codebase. Untangle it in public. Hand it back faster, safer, easier to ship on.

// 05 METHOD / PROCESS

How I /
actually ship.

STEP.01

Discover

Understand the business, constraints, and the real user. Write the brief before the code.

STEP.02

Prototype

Sketch, mock, ship a rough working slice end-to-end before polishing anything.

STEP.03

Build

Iterate in short loops. Ship every week. Test the parts that will hurt if they break.

STEP.04

Handoff

Docs, runbooks, and a team that can carry it without me. No hero dependencies.
