The Micro-Engagement Menu

Optimized for speed and focus. We skip the meetings and get straight to the code.

The Async Workflow

01

Select & Sync

Select your Micro-Engagement. We align asynchronously via email/Loom to confirm requirements. No lengthy discovery calls.

02

Deep Work

Execution. Your task is completed in deep-work isolation using your repo or a clean branch. Focus is on quality and tests, not meetings.

03

Async Handoff

Delivery. You receive a PR, a Loom walkthrough, and documentation. I iterate on feedback until you are ready to merge.

Common questions about how I work.

FAQ

What is a Micro-Engagement?

A Micro-Engagement is a high-impact, short-term contract focused on a specific outcome (like a performance audit or component build) rather than ongoing hourly work. It allows you to access specialized Angular expertise for critical problems without a long-term hiring commitment.

Why choose a Micro-Engagement over a Freelancer or Agency?

Traditional hiring models are often too slow or too expensive for focused technical problems.

Feature Freelancer Agency Micro-Engagement
Speed Varies Slow Fast (3-5 Days)
Cost Hourly High ($$$) Fixed Price
Expertise Hit or Miss Mixed Team Angular Expert

How is this different from your agency?

Scale Sail Agency handles large-scale migrations and long-term contracts. Here, I personally handle smaller, high-impact tasks (Micro-Engagements) that need expert Angular attention but not a full team.

What is your availability?

I strictly cap my freelance work to 10-15 hours/week to maintain high quality. Most "Micro-Engagements" are delivered within 3-4 business days.

Do you work hourly or fixed price?

I strictly prefer fixed-price, asynchronous engagements. I do not offer hourly billing or live meeting blocks, allowing me to focus deeply on delivering the best solution.
