I help startups connect APIs, automate workflows, and add AI features to their products. If your app needs to connect with external services like payment gateways, maps, CRMs, AI models, dashboards, delivery systems, or internal tools, I can build the backend logic, database flow, webhooks, and deployment setup needed to make everything work reliably. I can help you with: Third-party API integration OpenAI / Gemini / Hugging Face integration AI chatbots and automation workflows Webhook-based data sync Payment gateway integration Backend API development PostgreSQL / MySQL / MongoDB / SQL Server database design JWT authentication and role-based access Admin dashboards and analytics APIs Docker, Nginx, PM2, VPS, AWS, Render, and Vercel deployment My main stack: Node.js, Express.js, Fastify, ASP.NET Core, Python, FastAPI, React, Next.js, PostgreSQL, MySQL, MongoDB, SQL Server, Docker, AWS, Nginx, PM2, OpenAI API, Gemini API, Stripe, Twilio, ChangeNOW, Google APIs. Why clients choose me: I don’t just “connect an API.” I make sure the full flow is stable: authentication, validation, database updates, error handling, retries, logging, and production deployment. I have worked on booking systems, marketplace platforms, crypto exchange integrations, dashboards, authentication systems, and production deployments. Need to connect systems or add AI to your product? Message me and I’ll suggest the cleanest way to build it.

Note: Most of my "in progress" contracts are actually idle, i.e. the work is done, but clients haven't closed them yet. Hi, I'm Daniyal. I'm a software engineer with 8+ years of experience building web applications, automation tools, and integrations. My work ranges from full-stack development using Laravel, Django, Next.js, and React to automation projects involving PowerShell, Bash, Azure, Microsoft 365, Entra ID, and API integrations. A lot of the projects I work on involve eliminating manual work. Whether that's automating repetitive business processes, building internal tools, creating deployment scripts, integrating third-party services, or developing custom web applications, I focus on solutions that save time and reduce operational overhead. Some things I commonly help clients with: • Web applications and backend systems • PowerShell and Bash scripting • Azure, Microsoft 365, and Entra ID automation • API integrations and workflow automation • Data extraction, processing, and reporting • Custom business tools and internal platforms I value clear communication, quick turnaround times, and writing code that is easy to maintain long after the project is finished. If you need someone who can handle both software development and automation work, I'd be happy to discuss your project.
