Senior Software Engineer
Finfactor Sep 2024 — Present Java · Spring Boot · Kafka · ClickHouse · Redis · Kubernetes
I joined Finfactor when it acquired the LastByte engineering team.
I work on the Account Aggregator platform, mostly on backend systems, reliability, analytics, and internal tooling. It handles more than 10 million API requests a day for banks and fintech companies.
What I worked on:
- Moved a legacy Java application to Spring Boot without breaking the FIU and bank integrations already running in cloud and on-premise setups.
- Built a Kafka and ClickHouse pipeline for production events. We use it to understand traffic, provider success rates, user journeys, drop-offs, and billing.
- Built tools that let the support team follow consent and financial-data journeys, making onboarding and production issues easier to debug.
- Built dashboards that show clients where journeys drop off and how providers are performing.
