About

Rhema Mutethia
RM

Backend engineer with 2+ years building production systems. I design APIs, architect microservices, and integrate AI capabilities into real applications.

Most recently focused on financial technology—building document processing pipelines with AWS Textract, designing event-driven architectures with Kafka, and developing multi-tenant enterprise systems.

I care about systems that are maintainable, observable, and actually work under load. Not interested in over-engineering or chasing trends.

Selected Work

Financial Analytics 2026

Mpesa Wrapped

Problem

M-Pesa users in Kenya receive transaction statements as PDFs with no way to analyze their spending patterns or get insights into their financial behavior.

Approach

Built a document processing pipeline using AWS Textract to extract transaction data from PDF statements. Designed a classification system that categorizes transactions and assigns users spending personality profiles based on observed patterns.

Implementation

  • Spring Boot backend with REST APIs
  • AWS S3 for document storage, Textract for OCR
  • Redis for caching, RabbitMQ for async processing
  • WebSocket connections for real-time progress updates
  • MySQL for structured transaction data

Microservices 2025

Digital Banking System

Problem

Model a teller banking system with proper transaction handling, service isolation, and real-time processing capabilities.

Approach

Designed a microservices architecture with service discovery, API gateway, and event-driven communication. Each service handles a specific domain (accounts, transactions, notifications) with clear boundaries.

Implementation

  • Spring Boot microservices
  • Apache Kafka for event streaming
  • Eureka for service discovery
  • Spring Cloud Gateway for routing
  • JWT-based authentication

Marketplace 2024

MusiciansConnect

Problem

Musicians in Kenya lack a dedicated platform to offer services, find collaborators, and handle payments through familiar channels.

Approach

Built a marketplace platform with M-Pesa integration via the Daraja API. Focused on simple UX for non-technical users while maintaining proper payment handling and transaction records.

Implementation

  • Django backend with MySQL
  • M-Pesa Daraja API integration
  • User profiles and service listings
  • Transaction management system
