Needed reliable balance tracking and payment state management across multiple providers.
Designed a ledger-based system with idempotent webhooks and event-driven processing.
Payment flows were tightly coupled and hard to monitor or reconcile.
Built a unified layer with queue-based processing and webhook reconciliation.
Legacy system was slowing development and affecting reliability.
Led incremental re-architecture, improving performance without downtime.
Breaking down legacy systems into scalable, maintainable architectures.
Designing robust APIs and integrating external services safely.
Wallets, gateways, webhooks, reconciliation, failure-safe flows.
Dockerized deployments, Kubernetes, CI/CD, monitoring.
Map the current flow, identify bottlenecks, and clarify technical and business constraints before writing any code.
Build for retries, timeouts, recovery paths, and visibility into production behavior. Assume failure happens.
Roll out incrementally, monitor closely, and iterate based on real-world feedback. Production is the test.
Lessons from building transaction processing systems with proper idempotency, reconciliation, and failure handling.
Practical patterns for queues, workers, and async processing in production payment systems.
How to incrementally modernize a running system without breaking what already works.
Available for consulting, contract work, or full-time opportunities in fintech and backend engineering.
