Senior Smart Contract Engineer / Lead

As a Senior Smart Contract Engineer, I took over the existing Smart Contract product, where I was responsible for maintaining existing features and implementing new business requirements into the existing codebase. The solution was built using a proprietary Universal Product Engine (Core Banking) called Vault (by Thought Machine). The Smart Contract was developed by our team, delivering product logic while utilizing common functions provided by the Contracts API. The logic was parameter-driven and executed at specific times through various hooks (post-posting, parameter updates, schedules, etc.).

I contributed during the preparation phase—a 6-month period—during which we designed and implemented features. When the product transitioned to the production phase, our team was responsible for delivering backward-compatible solutions, as well as improving and refining the existing product.

The product included many features, most notably:

• Bankers' Automated Clearing System (BACS) process
• Generation of Payment Schedules and scheduling of events based on the schedule
• Account Cancellation / Not Taken Up (NTU) processes
• Reinstatements
• Forbearance process
• Changes to existing postings based on financial business requirements

Technologies:

• Python
• MS Azure
• CI/CD Pipelines
