Fetches the current advisor list and the high-risk country list, then — continuously integrating with the bank's web system via Selenium — lets the advisor enter data through a desktop wizard interface. Includes built-in business logic and data validation. At the end of the process it generates non-editable PDF account-opening documents and opens the account in the bank's web system. Supports maker/checker verification. Handles both new and existing clients (for existing clients, data is pulled from the client record in the banking system).
A twin process to the tool above, with data sourced from a lead in the bank's web system.
Manages the issuing and return of debit and credit cards. Also handles ordering cards from the supplier, generating reports on orders and process activity, emailing Excel attachments with security labels, logging events to a database, and automatically purging data per GDPR requirements. First launch is via a link that runs an installer and creates a desktop shortcut. User login uses RiscoSingleSignOn — an in-house equivalent of the bank's SingleSignOn.
Executes transfers in the bank's terminal and web transactional systems under various transfer types, and reconciles completed transfers against supplied reports. Handles 196 accounting instructions split across 2–4 accounting legs. Used across 12 different bank units. After recent updates, integrates with the bank's BOT for final entry into the Mainframe system.
Converts an Excel file containing the advisor list into a PostgreSQL database and exposes that data via WebAPI for other applications to consume.
Converts reports downloaded from OnDemand into Excel files according to defined business logic.
Modernized an existing C# application to use PostgreSQL instead of MS Access. Lets a reviewer score a recorded advisor–client call against a defined rubric, generates feedback as an email to the advisor, and files it on a network share.
Proposed the business process and built the tool that generates standardized, bank-wide values for the Country Info field used in account opening and, ultimately, AML reporting.
Verifies incoming payment demands for fees charged on outgoing international transfers, with source data pulled from the bank's web application.
Starts and stops databases, and runs automatic backups on a defined schedule with rotation of older backups.
Manages starting and stopping the team's WebAPI services and web applications.
An original, in-house equivalent of the bank's SingleSignOn mechanism, used to authenticate users across the team's applications.
