BankingClient
A banking client was reconciling transactions by hand every day. I built a desktop tool that pulls the data automatically, cross-checks it, and flags discrepancies — cutting a multi-hour manual process down to minutes.
Case Study
My Role
Solo build — automation engine, data processing, decryption pipeline, and UI.
Portal Automation
Built resilient browser automation against internal banking portals to extract daily transaction data, including handling legacy web frameworks with unreliable interaction patterns — solved with element polling and extended timeouts rather than brittle selectors.
Reconciliation Engine
Cross-checks internally extracted data against external bank statements to catch discrepancies automatically, replacing manual spreadsheet comparison.
Secure Data Processing
Built an encrypted data-processing pipeline (including nested archive extraction) to handle encrypted financial data delivered by partner systems, feeding into a transaction parser that separates and calculates debit/credit charges.
Persistence & UI
A local database tracking daily reconciliation summaries and automation history, wrapped in a desktop dashboard with per-module automation status and error visibility.
