Strategy, design and development of web and mobile products, from brief to launch. A single point of contact — Ethan.
what i do
Four offerings,
one signature.
Brief through ship, end-to-end. No hand-offs, no middlemen. Code, design and strategy come out of the same head.
Marketing sites, business platforms, customer portals. Next.js on the front, Laravel on the back when the domain calls for it. Nothing off-the-shelf.
- Custom architecture
- Back-office if needed
- Hosting & CI/CD
Slow app, scary codebase, team that can't ship anymore? I audit, document, and propose a stepwise modernisation path — without breaking everything.
- Written tech audit
- Remediation plan
- Progressive rebuild
Lighthouse 95+, Core Web Vitals in the green, clean indexing, schema.org. Optimisation is code and discipline, not a magic spell. Measured, never promised.
- Lighthouse audit
- Perf rebuild
- Technical on-page SEO
how i work
Five stages,
no improvisation.
A method isn't an agency slide deck. It's a discipline that prevents bad surprises and makes every delivery predictable.
01
Framing
We start with the real need, not a feature list. Scope, constraints, risky assumptions. If anything has to be said no to, it happens now.
02
Architecture
Technical architecture, user flows, data model. Structural decisions get made and written down — so we don't revisit them mid-build.
03
Design
Visual identity, interactive prototypes, component system. Design is never decoupled from code — what gets drawn must work technically and aesthetically.
04
Iterative build
Short sprints, regular releases on a staging environment, continuous QA. You see the project grow each week — no black box, no final big-bang.
05
Guided launch
Production deployment, hands-on training, written documentation. You leave autonomous, with a maintainable project and codebase knowledge that's yours.
daily tools
A tight stack,
mastered deeply.

about
Ethan,
fullstack developer.

Master's in web development. Apprenticeship then full-time at 3Codes, working on web and mobile projects with tight deadlines and non-negotiable quality. Alongside, I run Opaza — my studio, for the missions I pick.
The agency-plus-freelance combo is the real edge: methodical delivery instincts with the agility of an independent. One contact, the rigour of a team.

journal
Field notes.
Lessons learned, technical decisions argued out, and a few sharp opinions. Updates are irregular — only when there's something to actually say.

Why I still pick Laravel in 2026
Everyone's talking tRPC and serverless. I've spent six years building Laravel back-ends, and I'm not switching for the noise.

Expo OTA: 18 months in production
Over-the-Air updates saved two critical releases this year. Honest review, with the traps and the patterns that work.

Written framing, my best sales tool
A 6-page framing doc replaced all my detailed quotes. Here's how I write it, and why clients prefer it.

AI-augmented, without losing the thread
Claude Code, MCP, agents. How I integrate these without diluting responsibility for the shipped code — which stays mine.

Got a project?
Fastest path is a direct message. We see if the project makes sense, and if so, how to attack it.
