RAMP-UP PROFILE | SHORT FORMAT
Two Senior Django Engineers Embedded in 48 Hours Before a Peak Trading Window
Whatnot, a live shopping marketplace in the US, rebuilt its in-stream bidding and checkout path with Uvik Software as its engineering partner. The 13-month program covered real-time bid handling, checkout latency, and stream fan-out. In-stream checkout latency moved from six seconds to 400 milliseconds, and bids lost to latency fell from 8.4% to 0.3%.
At a glance
Inquiry to productive
| When | What happened |
|---|---|
| Day 0, 14:10 ET | Inquiry arrives. The client has six weeks to peak season and no capacity on the checkout path. |
| Day 0, 19:40 ET | Scoping call. Stack, seniority, overlap hours, and the specific service in scope are agreed. |
| Day 1 | Three vetted profiles delivered, inside the 24 hour commitment. Two are shortlisted the same day. |
| Day 2, morning | Two technical interviews with the client's engineering lead. Both engineers accepted. |
| Day 2, 16:00 ET | First engineer embedded. Repository access, environment, and standup attendance the same afternoon. 48 hours from inquiry. |
| Day 3 | Second engineer embedded. |
| Day 4 | First change merged to the checkout service. |
| Day 9 | Both engineers owning services independently, taking tickets from the client's own board. |
What made it fast
The stack was standard. Senior Django engineers with high-traffic transactional experience were available on the bench, so sourcing time was zero.
The client ran interviews within a day of receiving profiles. Interview scheduling is the single most common cause of delay, and it did not happen here.
Onboarding was one repository and one environment, not a full platform induction.
What would have slowed it down
Three things would have moved this from 48 hours to two weeks: a niche stack requirement, a security review requiring background checks or residency confirmation, or an interview panel that needed several diaries aligned. None applied. The 48 hour path is real, and it is the fast case, not the typical one.
Outcome
Both engineers were productive before the peak window opened. The engagement continued past the season and became the squad described in the full case study for this client.
The commitment behind this
- Vetted profiles inside 24 hours.
- Engineers embed from 48 hours.
- Two weeks is the outer bound for niche expertise.
