I'm a Software Engineer building distributed systems, automation tools, and full-stack applications β and currently building Lets Build Technologies, offering software services alongside my own SaaS products.
Previously at AWS (Managed Fleets, EC2 Core), I worked on internal tooling focused on:
- infrastructure visibility
- automation and reliability
- self-service control planes for customers
I enjoy working on problems involving:
- system design
- asynchronous processing
- backend services and APIs
- agentic AI as a system control plane
- cloud-native architectures
Backend: Java (Spring Boot), Python, Ruby on Rails
Frontend: React, TypeScript
Cloud: AWS (Lambda, SQS, EventBridge, API Gateway, Cognito, S3, CloudFront), Terraform
Data: PostgreSQL
AI: AWS Bedrock Agents, Gemini
Practices: CI/CD, IaC, testing, code reviews
A serverless ticketing platform evolving toward AI as the control plane, not just the frontend β customers will eventually describe intent in natural language and a multi-agent system (classifier β runbook-matcher β escalation) handles resolution.
- React/TypeScript frontend, Java Spring Boot API, Python async consumer
- AWS Lambda, SQS, Cognito, S3 β full Terraform IaC, phased and independently deployable
- π https://github.com/iamvusumzi/supportdesk
A distributed job discovery and scoring platform exploring asynchronous pipelines, AI-based analysis, and configuration-driven behavior.
- Python ingestion (Lambda), Java Spring Boot analysis/API, React dashboard
- Gemini 2.5 Flash scores roles against my profile and triggers Slack alerts on strong matches
- π Architecture: https://github.com/iamvusumzi/jobhunter-system
A SaaS platform aggregating South African government RFQs for SMMEs, live and growing β built in partnership with a compliance/PO-funding business for a tight product loop.
- Spring Boot/JPA on Neon Postgres, React/TypeScript frontend, AWS Lambda + EventBridge ingestion
- Building an agentic document-extraction pipeline (Textract + Bedrock Agents) for automated compliance verification
- π https://github.com/iamvusumzi/bidcure-showcase
- shipping AI-native systems where agents drive backend workflows, not just chat UIs
- deepening cloud architecture and IaC practice through real, deployable systems
- growing Lets Build Technologies and BidCure alongside hands-on engineering
- SDE roles with strong ownership and technical depth
