Full Stack Software Engineer at SysCon Inc. developing SysConcil, a multi-tenant data reconciliation SaaS platform.

At SysCon Inc., I develop SysConcil, a multi-tenant SaaS platform for data ingestion, validation, reconciliation, mismatch investigation, and reporting. I build its React and TypeScript interfaces and develop Python/FastAPI and PostgreSQL workflows, with tenant-aware access controls and background processing.

At Tech Mahindra, I supported enterprise integrations using Oracle SOA Suite, tracing REST and SOAP service flows and investigating data exchange issues. Earlier, at Vodafone Ghana, I reconciled service-usage records against billing outputs to identify discrepancies and support billing accuracy.
