Abhishek A.

Top Rated | 100% JSS | 15+ Years of Development & DevOps Experience I have been working in web and mobile app development and DevOps for 15+ years. I joined Upwork in July 2025 after years of working with direct clients and development projects. Since joining, I’ve maintained a 100% Job Success Score and Top Rated status. I build, customize, deploy and maintain web applications, mobile apps, APIs, AI automation and the servers they run on. I have hands-on experience with PHP, Laravel, CodeIgniter, MySQL, JavaScript, TypeScript, Node.js, Next.js, Python, REST APIs, WordPress, WooCommerce, iOS and Android. I also work with AI automation, AI integrations and LLM APIs, including applications that have been built or partly built using AI coding tools. If an AI-built application needs debugging, further development, API integration, database work or deployment, I can work with the existing code and take it forward.

I can work on a specific bug or feature, customize an existing application, build or integrate an API, connect an AI service, set up an automation workflow, troubleshoot email delivery, migrate a server, or handle development through production deployment. If you have a web application, mobile app, AI automation project, API integration, existing codebase, server or email delivery problem, send me the details.
