Client testimonials.

84EM works with agencies to assist with their client work, and directly with businesses.

We have managed 100% uptime for more than 1 calendar year, a feat that is frankly pretty incredible.

Andrew has been absolutely excellent. Over the past 2 years we've been working together, he's become more to our company than an incredibly talented full stack developer; he understands our brand and its goals and makes sure our digital presence is represented correctly. Any company looking for his services would be very lucky to have him on their team!

The difference a highly competent developer makes -- especially one who is responsive, clear, and reliable in communication -- cannot be overstated.

What makes 84EM different from other developers?

One principal engineer on every engagement with direct client access. No middle layer, no junior handoffs, no rotating teams. The person who scopes the project is the same person who architects it, writes the code, and ships it. 31 years of web experience, a 100% on-time delivery record, fast response times, clients ranging from solo founders to enterprises over $1B in revenue.

Will I work directly with the engineer doing the work?

Yes. 84EM's principal engineer is the point of contact and the accountable party from scoping through deployment. For larger engagements, a network of developers and specialists is brought in, but communication and accountability stay with the principal engineer.

How much does a project with 84EM cost?

Past engagements have ranged from small hourly tasks to multi-year retainers in the six figures. It depends on scope.

Does 84EM work with agencies?

Yes. 84EM offers both white-label and client-facing agency partnership models. See Agency Partnerships for details.

Do I own the code 84EM writes?

Yes. All custom code is owned by the client, with full repository access, documentation, and no lock-in.

How do I get started with 84EM?
