About Me

Software Engineer

Software Engineer II with 4+ years of professional experience, including 3+ years in the banking and fintech industry, building scalable, distributed backend systems. Specialized in Java and Spring Boot microservices, high-availability architectures, and real-time payment processing (SWIFT MT/MX, ISO 20022). I have hands-on experience delivering enterprise banking solutions, including SWIFT MT ↔ MX (ISO 20022) message conversion engines, multi-tenant SACCO core banking systems and payment integration platforms, where accuracy, compliance, and performance are critical. My work focuses on designing reliable, production-grade systems, optimizing databases, and integrating services supporting RTGS, SWIFT, and mobile payment workflows.

Projects

Enterprise systems and engineering solutions built across banking, integration, and infrastructure domains.

Core Banking & Financial Systems

Multi-Tenant Core Banking Solution
Scalable core banking platform supporting multi-entity financial operations and account processing.

Financial Reporting Platform
System for generating structured financial reports (balance sheets, statements, regulatory reports).

Enterprise API Gateway
Centralized routing layer for microservices, enabling secure and controlled service-to-service communication.

Messaging & Integration Systems

SWIFT MT ↔ ISO 20022 MX Converter
Built transformation engine for converting legacy SWIFT MT messages to modern ISO 20022 MX format using XML processing and validation rules.

SFTP Integration Platform
Automated file transfer and processing system for banking message exchange and scheduled ingestion pipelines.

Mobile Money Integration Middleware
Integration middleware layer connecting SACCO core banking systems with mobile money platforms. It enables real-time financial operations including deposits, withdrawals, loan disbursements, and loan repayments. The system ensures reliable transaction processing, data consistency, and seamless interoperability between core banking systems and external mobile money providers.

API Manager System
Integration middleware between external channels and the Finacle Core Banking System. It handles request orchestration, converts JSON ↔ XML formats, enforces idempotency to prevent duplicate transactions, and performs validation and message transformation before forwarding requests to the core banking system. The system operates behind an API Gateway which handles external traffic routing and security at the entry layer.

Infrastructure & High Availability Systems

High Availability Banking Infrastructure
Configured load-balanced and fault-tolerant systems using HAProxy, Keepalived, and multi-node deployment architecture.

Additional Engineering Work

SACCO Data Migration & Onboarding Platform
Designed and deployed an end-to-end migration system used to onboard SACCOs onto core banking platforms. The system automates data extraction, transformation, validation, and migration processes to ensure seamless transition of legacy SACCO data into production systems. It also supports structured onboarding workflows and provides technical enablement through documentation and training for implementation teams.

Loan & Transaction Processing Services
Backend services for automated financial processing workflows including validation, scheduling, and reconciliation logic.

Task & Utility Systems
Various internal tools and applications built using Spring Boot, Angular, Python, and PHP for automation and operational support.
