Scaling a Fintech Platform from 10K to 1M Users
The Challenge
Stratos Finance needed to scale their payment processing platform to handle 100x transaction volume within six months. Their existing US-based team of five engineers was stretched thin maintaining current operations while trying to rebuild core infrastructure for scale. Hiring domestically at the pace required was neither financially viable nor fast enough to meet their Series B growth commitments.
Our Solution
SMarDevs assembled a dedicated nearshore squad of four senior engineers specializing in distributed systems, event-driven architecture, and cloud-native development. The team integrated directly into Stratos's Agile workflow, participating in daily standups and sprint planning from overlapping time zones in Colombia and Argentina. Engineers were onboarded within two weeks and began contributing production code by their third week.
The Outcome
The platform successfully migrated to a microservices architecture with event-driven processing, achieving sub-200ms transaction latency at 10x the previous throughput. The combined team delivered the migration three weeks ahead of schedule, enabling Stratos to onboard enterprise clients on their accelerated timeline. The nearshore team remains embedded 14 months later as a permanent extension of the engineering organization.
“The SMarDevs engineers felt like an extension of our own team from day one. Their technical depth in distributed systems was exactly what we needed, and the time zone alignment meant we never lost a day waiting for handoffs.”
