Enterprise IT & banking systems — since 2008
System Administrator, Oracle/PLSQL Specialist, PowerCARD Admin, and FinTech Systems Builder — running the platforms banks depend on.
PowerCARD administration, card issuing operations, UAT/PROD coordination, vendor follow-up, and production support.
Oracle PL/SQL, Oracle BI/Analytics, Autonomous Database, reporting, dashboards, SQL analysis, and data validation.
API coordination, payment integrations, card schemes, ISO 8583 understanding, JIRA delivery, SOW/BRF review, and cross-team implementation.
A high-performance analytical database demo showcasing faster dashboarding compared with traditional Oracle-based reporting.
Enterprise card issuing, production support, UAT coordination, vendor delivery, and operational enhancements for banking systems.
Data-driven raffle, reporting, and business analysis solutions built around clean source data, validation, and automated outputs.
Support for payment-card related integrations, scheme changes, APIs, and transaction-flow analysis.
Eighteen years across banking systems, payments, Oracle engineering and IT leadership — from UNIX consoles at the Ministry of Finance to running PowerCARD for Bahrain's leading card issuer.
Owning parameter management in PowerCARD — the card management platform behind Bahrain's first and leading credit-card issuer & acquirer — and managing every change request to the system, end to end.
Ran the IT function for eight years — budgeting and procurement of infrastructure, supervising installation and maintenance of hardware, software and networking, supporting outsourced development teams on design and delivery, and keeping internal staff moving.
In-market readiness assessments, end-to-end mobile application testing across localized clients, handsets and regional operators, and in-market device testing for the Bahrain region.
Shell programming and system-log monitoring on UNIX, contributing to the HP Tru64 → IBM AIX 5L migration — printer integration, print-server cleanup — with a two-month contract renewed four times.
Card-transaction reporting lives on an Oracle estate that is rock-solid for operations — but exploratory analytics over large transaction volumes meant long-running queries and slow dashboard iteration for the business.
A working proof of concept pairing ClickHouse, a columnar OLAP database, with Apache Superset as the visualization layer. I modeled representative card-transaction datasets, loaded them into ClickHouse, and rebuilt key business dashboards on top.
A live side-by-side demo that made the case for columnar analytics in card-data reporting, and a reference architecture the BI team can grow into.
I own parameter management in PowerCARD, the card management system behind Bahrain's first and leading credit-card issuer & acquirer, and I manage every change request to the system end-to-end: analysis, configuration, UAT coordination with business teams, production deployment, and vendor follow-up with HPS.
100+ production & UAT deployments coordinated, with a track record spanning operations, development and administration of the same platform — a rare full-stack view of a card management system.
Replace a legacy raffle process for card-spend campaigns with a platform that is auditable, repeatable, and compliant with data-residency regulation — where transaction data and client personal data cannot simply live in the same place.
A complete business requirements document adopted as the blueprint for the replacement platform — plus a stream of recurring Oracle BI reporting, validation and automation work around it.
Keeping a card platform compliant is a moving target: schemes publish mandate releases on a fixed calendar, and every one lands as configuration, testing and coordination work.
Scheme releases delivered on schedule, network projects (including with the national switch) executed across environments, and transaction-flow issues diagnosed at the message level.
