How I engage.
Small, deliberate engagements. Mostly payments, queues, and multi-tenant SaaS. I pick one or two at a time so the work is actually good.

Process
Intake
A short chat or a two-line email, then a 30-minute call. I turn down engagements that are not a fit.
Scope
A written quote and a short plan. Both sides agree before any code moves.
Ship
One shared channel. Updates during the week, a working demo every Friday.
Handoff
Written docs, recorded walkthroughs, and a two-week warranty — I fix any bug I shipped for free.
Engagements
- 011–2 weeksFixed fee
Feature sprint
Pick one well-scoped feature — a new integration, a checkout flow, an internal tool. I ship it end to end, tested and live in your product.

- Shipped feature, live in your product

- Short doc on how it works and how to extend it
- 024–8 weeksWeekly
Infrastructure build
Build a working system from scratch. Designed, coded, monitored, and rolled out to your users without drama.

- Playbook for your team when something breaks
- Dashboards and alerts so you see problems early

Advisory retainer
A senior engineer on call, every week. I help with big technical calls, hiring, code review, and talking through outages after they happen.
Before we start
A quote and a one-pager — what I cover and how fast I reply.
You get
- Notes from every call
- Write-ups of major technical decisions
- Code review on your team’s pull requests
