- Ensured zero downtime of mission-critical applications and infrastructure, with deployment pipelines implemented using Docker, Kubernetes, and AWS. Reduced release cycles from weeks to daily without service interruptions.
- Improved application performance by 62% through the following: Leveraging Elasticsearch for quick searches across large datasets, handling as many as 3 million registered users. Implementing database indexing and also making queries lighter by excluding unneeded fields. Simplified the application's business logic to eliminate redundancy, optimizing core algorithmic time complexity from (O(n)) to (O(1)) and (O(n^2) to (O(log n)). Building functionalities from scratch using mostly utilities built directly into the core programming language/framework without having to install more external libraries, thereby making the application lighter.
- Ensured that the APIs and overarching backend architecture were built in line with security standards and compliance regulatory frameworks, such as NDPR, PCI-DSS, and OWASP Top 10, to ensure that software systems were built in line with the core cybersecurity principles of confidentiality, integrity, and availability.
- Also consistently implemented strong incoming request parameters/data validations, robust error handling, and audit logs/trail to further strengthen and maintain the integrity of software systems.
