MercadoPago: Staff augmentation for Latam's biggest Fintech
Marcos Ocon
COO at Develative
Marcos is the COO at Develative, now weekend Golfer trying to get better at it, currently at 10 of handicap.
About the Client
Fintech leader Mercado Pago dominates digital payments across Latin America. In 2021 it bought Chilean POS specialist Redelcom, inheriting a Ruby-on-Rails monolith that already served 65 000+ merchants. Across the wider region, Mercado Pago ships >1 million smart terminals per quarter—scale that demands bullet-proof uptime.
The Opportunity
The mandate: re-platform Redelcom’s Rails codebase into Mercado Pago’s Golang micro-service mesh without a single minute of merchant downtime, all while adding support for QR-payments and next-day settlement.
The Solution
Zone-Defense Refactor – Stripped the 220 k-LOC Rails app into 11 bounded-context services, exposing gRPC + REST endpoints.
Blue/Green & Canary Kicks – Built GitLab-CI pipelines with feature flags; traffic was shifted 10 % at a time until 100 %, ensuring zero-downtime cut-over.
Peak-Load Conditioning – Added Kafka event streams and horizontal-autoscale pods, doubling throughput headroom to 2 k TPS.
Omnichannel Scoreboard – New reconciliation service aggregated e-commerce + POS sales, surfacing real-time dashboards for 65 k merchants.
Defence-in-Depth Hardening – Implemented tokenised PAN storage, HSM-backed signing and enclave-sealed secrets to meet PCI DSS v4.
The Impact
KPI | Before | After | Value-Add |
|---|---|---|---|
Merchant onboarding latency | 48 h | 30 h | Faster revenue capture for SMEs |
Peak TPS on POS API | 1.2 k | 2.0 k | Ready for Black-Friday spikes |
Platform availability | 99.90 % | 99.98 % | Aligns with Mercado Pago SLA |
