How much does the fullstack engineering retainer cost?

The Starter retainer is $1,000/month for 20 hours. Core is $1,500/month for 30 hours with feature development and weekly syncs. Premium is $2,500+/month for 50 hours with on-call and architecture input. All tiers include a cancel-anytime policy with 30 days notice. A 1-week paid trial is available for $400 (10 hours, full refund if not satisfied).

What tech stack do you support?

React, Next.js, TypeScript, Tailwind CSS on the frontend. Python, Django, FastAPI, PostgreSQL, Redis, Celery on the backend. AWS (ECS/EKS/Lambda/S3), Docker, Kubernetes, GitHub Actions for infrastructure. LangChain, LangGraph, CrewAI for AI and automation.

How quickly can you start?

I can typically start within 3 business days. After a free 15-minute discovery call, I send a custom proposal within 24 hours. Once agreed, I do a codebase assessment and deliver first results within the first week.

Is this a full-time hire or a contractor arrangement?

This is a monthly retainer with an independent contractor - not a full-time hire. You get 20–50 hours/month of dedicated senior engineering without the cost of a $120k+ salary, benefits, or 90-day ramp-up. Cancel anytime with 30 days written notice.

What if I'm not satisfied with the work?

Start with the 1-week paid trial ($400 for 10 hours). If you're not satisfied, you get a full refund - no questions asked. This lets you verify the quality before committing to a monthly retainer.

The Problem

Sound Familiar?

Most SaaS teams hit the same wall. You're growing - but your engineering capacity isn't keeping up.

Bugs pile up while features ship late

Your team is stretched across too many priorities. Critical fixes sit in the backlog for weeks.

No one owns DevOps or infrastructure

Deployments are manual and fragile. Infra debt compounds. Nobody has time to fix it properly.

Can't justify a $120k full-time hire

You need 20–30 hours/month of solid fullstack help. Not another salary, benefits, and 90-day ramp-up.
