Ad fraud detection system

The company, a growth-stage startup inAdTech headquartered in Colombia, needed to solve this challenge: “ad frauddetection system”. More than business knowledge, what was missing wasverifiable experience in the project's specific technical stack: a previoushiring attempt hadn't worked out, generating extra cost and delaying the marketopportunity. On top of this, there were methodological problems in team andproject management: inconsistent agile ceremonies, poor visibility intodependencies, and a delivery cadence that was hard to predict. The budget wastight, leaving no room to absorb additional overruns or delays.

Squad Challenge designed 4 challenges,one per position, based on the business case itself, with an average of 5candidates analyzed per position (20 evaluated in total), delivering the finalshortlist in 2 days. Since the client also raised methodological problems inteam and project management, Squadmakers recommended bringing in an additionalScrum Master for the squad.

Squad Hiring managed, within 24h, theAOR-based hiring of the candidates validated through Squad Challenge, handlingcontract generation adapted to each developer's country of origin, datavalidation, and the onboarding process.

An Enabling Team with specialists inDevOps and data and AI joined temporarily for 12 months to speed up deliveryand transfer best practices. The methodology the Enabling Team applied was, asalways, an adaptation of Agile to the client's type of organization. Since theproject also required a maintenance and support team, a specific methodologywas also developed for that team, independent from the development squad's.

The squad brought on 5 profiles (mobile developer,Squad Lead, backend developer, ML engineer, Scrum Master) working on a stack ofPython (FastAPI), Vue.js, ClickHouse, BigQuery, GitHub, OVH, Kotlin (Android)and Swift (iOS). The company had no consolidated in-house technical team, sothe professionals proposed by Squadmakers, brought on under the AOR model,operated as the product's engineering core from day one. The engagement ran for12 months in total.
