Hadoop Data Platform Migration for a tier-1 bank
Refreshed a bank-wide on-prem Hadoop platform by migrating HDFS data onto S3-compatible storage with minimal impact on production. Then built a low-touch, serverless, file-based replication tool-as-a-service across 70+ storage engines — 10–50% faster than AWS S3 sync, with near real-time replication and point-in-time restore against versioned buckets.

AWS account vending automation for a retail bank
Refactored how one of South Africa's largest retail banks vends and configures AWS accounts. GitOps workflows plus home-grown Terraform modules and providers took account turnaround from days to minutes — with the regulated controls baked in and the manual mistakes designed out.

Near real-time data mart for ServiceNow IPC & CMDB
Replaced an expensive, inflexible third-party integration with a serverless ELT pipeline on API Gateway, Lambda, RDS, and Glue. Near real-time ingestion of ServiceNow data and a 4× cut in infra footprint — flexible enough to track schema changes as they happen.

Credit risk scoring on Redshift
A scoring mechanism that takes an ID number, joins it with the bank's existing Redshift estate, and returns a credit risk score in real-time. The output drives which products and limits each customer qualifies for — same data the rest of the bank uses, scored consistently every time.

Secure integration API gateway for vendor & third-party access
A single, governed front door for every vendor and partner integration into the client's AWS estate. Cognito for auth, WAF for protection, IP allow-listing for control. Developers ship new endpoints with Terraform and a Lambda layer; each consumer gets credentials scoped to only what they're allowed to talk to.

Enterprise Q&A bot, CATBOT
One place to ask anything across the org. GenAI handles the questions that have good answers in the docs; humans handle the ones that don't — and their answers feed straight back into the knowledge base. Every response cites its source, so the platform earns trust as it grows. The same framework now spins up domain-specific bots in days.
