What I Do?
Full Stack Web Development
I design and develop scalable, secure, and high-performance web applications using frameworks like Laravel, React.js, Vue.js, and Node.js. From crafting robust RESTful APIs and GraphQL endpoints to building responsive, user-friendly frontends, I deliver end-to-end solutions that enhance user engagement and streamline business operations. My work on projects like the Rentleey Real Estate App and NAUTH Election Website demonstrates a 70% increase in user retention and seamless backend-frontend integration.
Cross-Platform Mobile App Development
Flutter, Kotlin, and Swift, I create dynamic, cross-platform mobile applications for iOS and Android that prioritize performance and user experience. I integrate features like real-time push notifications (Firebase, AWS SNS), offline-first capabilities, and secure payment gateways (Paystack). Projects like the Nurse Ready App and Cusecho showcase my ability to drive 40% increases in user interaction and ensure compatibility across devices.
Desktop Application Development
I build robust desktop applications using C# and MSSQL, tailored to specific business needs. My pharmacy and medical lab management system, currently used by two pharmacies, optimizes inventory, billing, and reporting processes, improving operational efficiency by 25%. With a focus on clean architecture and reliable database integration, I deliver desktop solutions that are scalable and user-friendly.
Cloud Integration and DevOps
I architect and deploy cloud-based solutions using AWS (Amplify, S3, DynamoDB, SNS) and implement CI/CD pipelines with tools like GitHub Actions, Codemagic, and Fastlane. My expertise in optimizing deployment workflows has reduced app deployment times by 25%, as seen in projects like Speedview and FollowMeBet. I ensure secure, scalable infrastructure that supports seamless application performance.
API Development and Third-Party Integrations
I design and implement secure, efficient RESTful APIs and GraphQL services to enable seamless communication between frontends, backends, and third-party systems. My integrations with tools like Paystack, Cloudinary, Agora, and WebRTC have powered features like real-time payments and video/audio functionalities, boosting user engagement by 70% in apps like Rentleey and 9jaEduGames.
UI/UX Design and Implementation
I translate high-fidelity designs (Figma, Adobe XD) into responsive, intuitive user interfaces using Flutter, React.js, and Vue.js. By combining clean code with state management solutions like BLoC, Provider, and Redux, I create visually appealing, performant applications. My work on the Nuthoop Shopping Platform and FollowMeBet ensured a 15% increase in active users through engaging, user-centric designs.
Database Design and Management
I architect and optimize relational (MySQL, PostgreSQL, MSSQL) and non-relational (MongoDB, Firebase Firestore, DynamoDB) databases to ensure data consistency, security, and scalability. My optimizations, including caching and indexing, have achieved 30% faster query response times in projects like the pharmacy management system and Rentleey, supporting real-time updates and offline capabilities.
Technical Consulting and Mentorship
With a passion for fostering tech talent, I provide technical consulting and mentorship, having trained over 100 developers in Flutter through the Google Developer Group. I offer expertise in project planning, technology selection, and process improvement, helping clients and teams achieve a 25% increase in productivity, as demonstrated in my leadership roles at DafeSoftware and GDG.
