CLIENT_REVIEW

"84EM is nothing but a breath of fresh air in a world of unreliable vendors."

Why do agencies choose 84EM?

Senior-only execution from one engineer, flexible white-label or client-facing positioning, and on-time delivery agencies have trusted for over a decade. One person handles architecture, development, and deployment, with no middle layer relaying messages to a rotating team.

Senior-Only Execution

31 years of experience, not a team of juniors managed by a PM. One person handles architecture, development, and deployment -- eliminating the miscommunication that sinks agency projects.

Flexible Positioning

White-label, client-facing, or somewhere in between. Whatever works for your client relationship. If you want 84EM invisible, 84EM is invisible. If you want to introduce 84EM as a partner, that works too.

How does 84EM deliver for your agency?

Four stages: scope and brief, build, QA and handoff, then ongoing support. 84EM works white-label behind your team against your spec and process, delivering to your staging environment tested against your acceptance criteria, while your agency stays the client’s point of contact.

01

Scope & Brief

You send a scope, spec, or brief. 84EM reviews it and confirms timeline, deliverables, and positioning -- white-label, client-facing, or hybrid.

02

Build

84EM handles architecture and development against your spec. Progress updates on your schedule -- Slack, Basecamp, email, whatever your team uses.

03

QA & Handoff

Delivered to your staging environment, tested against your acceptance criteria, with documentation your team can use for ongoing maintenance.

04

Ongoing Support

Bug fixes, change requests, and maintenance after launch. Same engineer, same direct communication. Available for the next project when you need it.

Overflow partner or a new hire?

A full-time hire makes sense when there is enough day-to-day work to keep someone on staff busy full-time. An overflow partner like 84EM makes sense when you need senior capacity without a salary, whether that is a volume spike or steady, predictable work over years. 84EM works white-label or client-facing, whatever fits your client relationship, and has delivered for agencies for over a decade.

Bring in 84EM when

  • You need senior capacity without adding headcount
  • Project volume spikes past your team’s capacity
  • A project needs senior depth you don’t staff in-house
  • You want white-label or client-facing delivery, one-off or ongoing

Hire in-house when

  • There is enough day-to-day work to keep someone busy full-time
  • The role needs daily presence across many small tasks
  • Deep institutional knowledge must live on your payroll
  • You are building a permanent engineering function

I've had the pleasure of working with Andrew at 84EM for over four years, and he's consistently been an exceptional partner across a range of development needs. From deep backend portal work to modernizing legacy code and building custom solutions tailored to our clients, his contributions have had a direct, meaningful impact improving overall site performance while enhancing reporting capabilities and activity tracking.

Supporting a complex 13-site ecosystem with multiple API integrations is no small task, yet Andrew approaches these challenges with both technical expertise and thoughtful problem-solving. He's proactive in identifying potential issues, staying on top of updates in the development space, and ensuring that our clients' websites remain secure, stable, and current.

Equally important, he communicates technical recommendations clearly and accessibly, making them easy to understand for those without a technical background. Beyond his skill and knowledge, Andrew has been a valuable mentor to our internal development team, always collaborative, reliable, and committed to delivering high-quality results.
