Ad fraud detection system

The company, a growth-stage startup in AdTech headquartered in Colombia, needed to solve this challenge: “ad fraud detection system”. More than business knowledge, what was missing was verifiable experience in the project's specific technical stack: a previous hiring attempt hadn't worked out, generating extra cost and delaying the market opportunity. On top of this, there were methodological problems in team and project management: inconsistent agile ceremonies, poor visibility into dependencies, and a delivery cadence that was hard to predict. The budget was tight, 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 5 candidates analyzed per position (20 evaluated in total), delivering the final shortlist in 2 days. Since the client also raised methodological problems in team and project management, Squadmakers recommended bringing in an additional Scrum Master for the squad.

Squad Hiring managed, within 24h, the AOR-based hiring of the candidates validated through Squad Challenge, handling contract generation adapted to each developer's country of origin, data validation, and the onboarding process.

An Enabling Team with specialists in DevOps and data and AI joined temporarily for 12 months to speed up delivery and transfer best practices. The methodology the Enabling Team applied was, as always, an adaptation of Agile to the client's type of organization. Since the project also required a maintenance and support team, a specific methodology was 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 of Python (FastAPI), Vue.js, ClickHouse, BigQuery, GitHub, OVH, Kotlin (Android) and Swift (iOS). The company had no consolidated in-house technical team, so the professionals proposed by Squadmakers, brought on under the AOR model, operated as the product's engineering core from day one. The engagement ran for 12 months in total.
