Glover

As a Senior Backend Engineer at Glover, a premier Nigerian Fintech company, I was instrumental in fortifying and scaling a platform that serves thousands of users daily. Glover provides a suite of digital services including gift card trading, crypto payments, and airtime-to-cash conversions. My tenure was defined by solving critical infrastructure challenges, enhancing system security, and enabling rapid product growth through robust backend architecture.

Key Contributions & Technical Impact

🔐 Advanced Login Security & Fraud Prevention

I architected a custom security layer designed to detect and flag suspicious login activities. By analyzing user behavior patterns—such as cross-border logins within suspicious timeframes—the system proactively protects user accounts.

• Impact: Significantly reduced account takeovers and provided users with transparent audit logs of their account activity.

🚀 Zero-Downtime Infrastructure Migration

One of my most significant technical achievements was leading the migration of the core monolithic application from Laravel v7 to v12.

• Challenge: The codebase was legacy, containing redundant logic and deprecated dependencies, operating on a live system with high daily active users.
• Solution: Executed a strategic, incremental upgrade plan that modernized the framework without a single minute of downtime.
• Outcome: Boosted system performance, patched critical security vulnerabilities, and improved developer velocity for the entire team.

💳 Secure Giftcard OCR System

To combat fraud and reduce manual review overhead, I built a smart validation system for gift card trading.

• Innovation: Integrated Google's OCR API to automatically scan and extract card details.
• Security: Implemented a complex validation logic that checks encrypted card data against a massive database of historical records to prevent duplicate usage.
• Performance: Optimized the search algorithm to perform these duplicate checks on encrypted data in real-time, ensuring a seamless user experience without compromising security.

🎁 High-Volume Rewards Distribution System

I engineered a resilient rewards engine for the company's "Holidays Reward" event.

• Scale: The system successfully processed and delivered card pins to thousands of users simultaneously via email.
• Reliability: Designed for fault tolerance to ensure every single reward was accounted for and delivered, maintaining 100% data integrity under heavy load.

🤝 Brand Ambassador & Affiliate Platform

I developed a comprehensive dashboard for managing the company's marketing campaigns.

• Features: Enabled brand ambassadors to track their performance, manage campaigns, and view real-time leaderboards.
• Backend: Built the logic for tracking referrals, calculating complex commission structures, and automating reward payouts.

💡 Infrastructure Optimization

Beyond feature development, I consistently worked on system infrastructure upgrades. I identified and removed dead code, optimized database queries, and introduced rigorous testing standards using PestPHP (migrated to industry-standard tools) to ensure code reliability.
