I developed and enhanced the payment management API for a peerless core banking solution, ensuring secure financial transactions, branch-level cash management, and audit compliance. The system was built using JavaScript, TypeScript, Node.js, NestJS, Sequelize, and PostgreSQL and was deployed on an on-premises infrastructure.

I developed a secure financial application for a financial institution serving agricultural SMEs and smallholder farmers. The system was built with TypeScript and NestJS, running on Node.js with MongoDB as the database.

TECHNICAL IMPLEMENTATIONS AND RESPONSIBILITIES
• Security and Encryption: Implemented AES-CBC encryption for all payloads to ensure secure data transmission.
• Authentication and Authorization: Integrated session authentication alongside JWT to enforce secure access control.
• Logging and Monitoring: Configured Elasticsearch for centralized log management and integrated application performance monitoring (APM) for system insights.
• Cloud Storage: Utilized Azure Blob Storage for secure document and file storage.
• Testing and Quality Assurance: Developed unit and integration tests using Jest to ensure system reliability.
• Back-end Development: Designed and implemented NestJS-based API services with scalable and modular architecture.
• PDF Generation: Implemented Puppeteer for automated agreement, approval, and contact PDF document generation, enhancing reporting and documentation capabilities.

I developed a loan application website where users can apply for loans, track their status, and view loan details. Loan eligibility is determined based on a credit score calculated from the user's financial data and a background check.

TECHNICAL IMPLEMENTATIONS AND RESPONSIBILITIES
• Authentication Services: Developed the authentication route using session-based JWT for secure authentication.
• Loan Application Processing: Implemented the loan application API, enabling users to submit financial details for loan eligibility assessment.
• Loan Calculator: Built the loan calculator API to compute the loan amount, interest rate, and total repayment.
• File Uploads and Storage: Integrated Cloudinary for secure document uploading (e.g., ID verification, financial statements).
• Database Management: Used PostgreSQL with Sequelize ORM for structured and efficient data handling.
• Project Management and Collaboration: Used Jira for task tracking and Git for version control.

Developed a back-end API to process IoT data from smart electric meters, enabling real-time power usage tracking, remote meter control, and online bill payments. The system supports high scalability to accommodate increasing users over time.

TECHNICAL IMPLEMENTATIONS AND RESPONSIBILITIES:
• IoT Data Processing: Developed API endpoints to receive and store energy usage data from smart meters every 60 seconds for real-time tracking.
• Payment Integration: Integrated the Interswitch payment gateway for secure debit card-based transactions.
• User Dashboard Development: Built and optimized API endpoints to support the React-based dashboard, enabling users to view daily, weekly, and monthly energy consumption.
• Scalability and Performance: Designed the system to handle increasing IoT data loads and ensure fast response times for the user dashboard.
• Collaboration and Agile Workflow: Used Scrum, Git, and Asana for project management and efficient team collaboration.
