Engineering teams that ship regulated software — payments, lending platforms and applied AI.

Engineering on GTS+ / GTSM+, the platform Toyota dealers and independent repairers across Europe use to diagnose, licence and reprogram vehicles — a hybrid estate spanning AWS and Toyota's on-premise systems.

• Spring Boot services on EKS Fargate behind a Kong API gateway, Akamai and CloudFront, with Kafka event streaming and MongoDB and relational stores.
• GTS+ Licence Signing Service and MSK issuance — the REST interfaces that authorise a diagnostic tool against a vehicle.
• Federated single sign-on across Toyota and partner identity providers over OAuth 2.0 and OpenID Connect, for dealer and independent-repairer populations.
• PKI and certificate lifecycle for the KMC 2.0 programme: client certificate generation, two-way SSL, CSR handling and root certificate provisioning through pre-production and production.
• Large-scale MongoDB migrations with binary backup, checkpointed resume and full rollback, run against live production data.

Build and release ownership of the GTSM+ service platform for Toyota's South African market operation, from source through to the production Kubernetes cluster.

• Java 11 and Spring Boot microservices — authentication, web services, licence and MSK, and the dealer-facing front end.
• Containerised delivery into Toyota's private Harbor registry and onto VMware Tanzu Kubernetes clusters, with Azure DevOps pipelines.
• Multi-environment release governance across QA, UAT and production, including controlled database change promotion.

Automation of the AppDynamics observability estate — installation and version upgrade across every environment the business runs, instead of a manual rollout repeated platform by platform.

• One automated path covering all four target environments: AWS, Microsoft Azure, Google Cloud and on-premise infrastructure.
• AI tooling used to build and maintain the automation itself, compressing work that had been hand-run per host and per environment.
• Consistent agent versions and repeatable upgrades, so monitoring coverage no longer drifts between clouds.

A four-workstream programme for a gold-loan lender: the customer payments product, its regulatory reporting, its security clearance, and the requirements for its next-generation core system.

• SBIePay payment gateway integrated into a Flutter app and an AWS Lambda backend — net banking, cards and UPI, with double verification, refunds and alerting.
• Application security review prepared for State Bank of India merchant onboarding: mobile, static, API, cloud and transport assessment with a full remediation register.
• Automated SFTP reporting to all four credit information companies — CIBIL, CRIF, Equifax and Experian — with retries, dated archival, S3 lifecycle and failure alerts.
• Requirements specification for an in-house gold-loan management system: origination, custody, maker-checker approval, accrual, collections and double-entry ledger.

Retained production support, maintenance, monitoring and enhancement of the MBO salon appointment, payment and management platform, taken over through a structured knowledge transfer from the incumbent support team.
