Systems in service, not mockups

Work Smart is a young agency and says so. Instead of screenshots without context, here are three systems actually built, with what was broken, what was done, and the numbers measured afterwards. The first two run in production today.

A platform that takes payments for training, built in five days

The problem

The seven courses were sold on paper. An interested visitor filled in a contact form, waited for a reply, and everything else happened by phone and from memory. No seat was held, no payment was traced, and nothing prevented twelve people being enrolled into a room for ten.

What was done

A complete database and a four-step enrolment funnel, with a seat held for thirty minutes, payment declaration, manual validation from a back office, automatic emails and certificates publicly verifiable by code. The catalogue injects itself into the existing course pages without rewriting their content, which preserves the search rankings already earned.

The technical guarantee

Overbooking is impossible, not merely unlikely: an exclusive lock at reservation time, a table-level constraint that not even an application bug can cross, and a unique index against double enrolment. Three independent protections rather than one check on screen.

  • 15tables, every one protected row by row
  • 40written access rules
  • 5days from design to going live
  • 0external libraries shipped

The result

The platform has been in service since 13 August 2026. A paid enrolment was carried end to end, from holding the seat to the printable receipt. Three manual payment methods are in place, and the schema already provides for automatic Mobile Money collection: on the day of registration, no migration will be needed.

A rebuild that was measured, not just pretty

The problem

The site did its job but did not stand comparison with the international agencies a decision maker measures us against. Worse, the first visitor of the day waited nearly thirteen seconds before seeing anything, because the hosting shuts the application down when traffic stops.

What was done

A complete black and gold design system, restrained motion driven by scroll and pointer, discipline sheets that open without leaving the page, a booking page, a 404 page, structured data, and an English version on real addresses rather than a JavaScript toggle. All of it without adding a single library.

The technical guarantee

Nothing went live on an impression. Every delivery goes through an automated campaign: eighteen pages checked at nine screen widths, from 1920 down to 320 pixels, plus interaction tests with the keyboard, under reduced motion and with JavaScript disabled. Five defects were found and fixed before publication.

  • 12,7 s → 0,73 sto the first byte
  • 162page-by-width checks, no overflow
  • 20English pages now indexable
  • 53 Koactually transferred for the homepage

The result

The site is live, bilingual and indexable in both languages. Response time was divided by seventeen by keeping the application awake. An estimator now gives a price range without waiting for a reply, and every request received is recorded in the database rather than living only in an inbox.

Work Smart project Web performance August 2026

A homepage cut from 9.1 MB to 81 KB

The problem

The homepage weighed 9.1 megabytes, including a 1.2 MB logo displayed at 32 pixels. On an ordinary Cameroonian mobile connection that is a minute of waiting, so a visitor lost. The same CSS was copied into nine pages, and sixty-one internal links were broken.

What was done

Images resized and converted, a single shared stylesheet, links repaired, mobile navigation added to every page, and costly decorative effects removed. The site became bilingual along the way, with French as the source and English as a dictionary.

The technical guarantee

The site published twelve testimonials from clients who did not exist, and invented statistics including a 350% return on investment. All of it was removed, at the cost of social proof, and replaced by written commitments you can hold us to. An agency that sells security cannot lie on its own homepage.

What this page does not do

Three internal projects, and we say so

The three systems above were built by Work Smart, for Work Smart. They prove technical skill and a method, not a long client list. Client engagements will be published here as soon as their results are measurable and their owners have given written permission. No case study will be published without both conditions.

Your project could be next

Estimate it in two minutes, or let us talk for thirty. Either way you leave with a clear direction.
