What I work on
A focused view of the engineering areas behind the selected work—from core-banking customization to safe technical delivery.
Pillar / 01
Core Banking Engineering
Customizing Temenos Transact workflows, screens, routines, and integrations for complex core-banking requirements.
- Temenos Transact (T24)
- Java Extensibility L3
- InfoBasic
- Record Lifecycle
- Versions & Enquiries
- OFS messaging
- TAFJ tooling
Text equivalent: A business workflow is expressed through a Transact screen or enquiry, then handled by Java and InfoBasic customization before a controlled core-banking process. This is conceptual and not a production diagram.
Pillar / 02
API & Integration Engineering
Building and supporting API flows that connect external channels, integration layers, and core-banking services.
- IRIS Dynamic APIs
- Apache Camel
- Java
- REST APIs
- Spring Boot
- ActiveMQ
- OFS
Text equivalent: A digital channel sends a request to an API or IRIS layer. Apache Camel routes it through generalized provider processing to a core-banking service. This is conceptual and does not represent a client production topology.
Pillar / 03
Cloud & Platform Engineering
Supporting containerized deployment, cloud environments, monitoring, and safe operational change around enterprise applications.
- AWS
- Docker
- Kubernetes
- ELK
- Packaging & deployments
- T24 upgrades & patches
Text equivalent: An application is prepared as a container image, deployed into a Kubernetes environment with generalized AWS-hosted services, and made observable through logs and operational visibility. This is illustrative only.
Pillar / 04
Automation & Quality Engineering
Using automation, testing, monitoring, and practical troubleshooting to improve repeatability in technical delivery.
- Karate Framework
- API testing
- API monitoring
- Python
- Bash
- Shell & Batch
- Root-cause investigation
Text equivalent: A change or API workflow is validated automatically, producing results and diagnostics that support monitoring or follow-up. The flow is illustrative and contains no live operational data.

04 / Approach
Engineering principles
01
Reliability
Complex financial systems require careful implementation, troubleshooting, and change delivery.
02
Clarity
Integrations and customization should be understandable to the teams that maintain them.
03
Reusability
Shared Java and InfoBasic utilities can make repeated work more consistent.
04
Safe change
Packaging, testing, deployments, and monitoring are part of engineering work, not afterthoughts.
05
Continuous learning
An ongoing interest in computer science and emerging technologies informs practical engineering work.
