The Challenge
What they were up against
Spend The Bits needed a robust B2B finance application and retail crypto wallet that could handle high transaction volumes with near-zero downtime.
Legacy payments stack suffered 20%+ downtime during peak transaction windows
No observability — outages were discovered only via customer complaints
Monolithic codebase slowed every release cycle to a crawl
Crypto wallet lacked compliance-ready audit trails
Our Approach
How we moved in
We built the complete platform from scratch and executed a full Kubernetes migration, transforming their infrastructure from frequent outages to enterprise-grade reliability.
Discovery sprint to map every failure mode in the existing system
Microservices architecture with independent scale per transaction class
Zero-downtime Kubernetes migration executed behind feature flags
Observability-first rollout — Prometheus + Grafana before business logic
The solution, in detail
Event-driven payments core on Kafka with idempotent retries
Retail crypto wallet with HSM-backed key custody
Real-time reconciliation engine for B2B finance flows
Automated CI/CD across staging, UAT, and production
