About

Full Stack Developer | Web, Mobile & API Expert

I’m Collins Njoka, a Full Stack Developer with extensive experience in building robust, scalable, and user-friendly digital solutions for clients around the globe. I specialize in Web and Mobile Development, crafting modern, responsive websites and high-performance Android, iOS, and cross-platform mobile apps tailored to user needs and business objectives. With a strong grasp of both frontend and backend technologies, I take pride in developing solutions from concept to deployment, ensuring each project is intuitive, visually appealing, and functionally sound. I also provide API Development and Integration services, creating secure, efficient REST and SOAP APIs that allow systems to communicate seamlessly. In the fintech space, I’ve successfully integrated various Payment Modules, including mobile money, credit card processing, and bank APIs, enabling businesses to transact efficiently and securely. My services extend to Debugging and Code Optimization, helping businesses troubleshoot and fix broken features or poorly performing code in existing systems. With a strong foundation in Database Management, I design, manage, and optimize PostgreSQL, MySQL, MSSQL, and SQLite databases to support high-performance applications. I also offer GIS Integration, configuring and embedding geospatial services using tools like GeoServer into web and mobile platforms for real-time mapping and spatial analytics. Additionally, I develop firmware and applications for IoT Devices, ensuring seamless communication between hardware and cloud services. My background in C#, VB.NET, PHP, Dart, Kotlin, JavaScript (Node.js & React), C++ for IoT, Python, and Django—combined with my soft skills in communication, problem-solving, and time management—makes me a reliable and versatile development partner. I’m passionate about creating digital products that are not only functional but also beautifully designed and easy to use. I’m currently available for remote freelance projects and always eager to collaborate with individuals or organizations looking to bring their ideas to life. If you need a dedicated, experienced developer to build, integrate, or improve your digital systems, I’d love to hear from you.
