What I'm looking for

I’m looking to build reliable, compliance-aware backend services in fintech—owning REST/SOAP APIs, payments logic, and audit trails—while working in agile teams that value clean code and production ownership.

I’m a backend software engineer with 2.5+ years building and maintaining high-volume financial systems for a global fintech (i2c Inc.). I focus on core Java and API development, especially REST and SOAP services, with an emphasis on clean, maintainable, compliance-aware code.

In payments and card-processing domains, I’ve engineered BNPL excess-payment posting and reversal logic across multiple installment-charge calculation methods, added adjustment support for flexible repayment configurations, and delivered joint-account closure request logging and dispute logging support. I’ve also resolved production issues that blocked card reissuance when disputes were logged, restoring core customer-facing flows and supporting Temporary Credit Limit (TCL) scenarios.

I’m proud of the audit-trail systems I’ve built for high-volume financial tables (100K+ records) using SQL triggers, stored procedures, and history tables on Informix—ensuring compliance traceability for card-data mutations. Beyond payments, I enjoy building with Spring Boot and data-focused pipelines, including an ETL project for ATM transaction data using Kafka, Spark, Presto, Superset, and Cassandra.
