About Priyadeep

I help startups and growing businesses turn ideas into production-ready AI-powered backend systems and modern web applications.

I’m an AI-focused Backend Engineer specializing in building scalable APIs, intelligent automation features, and SaaS-ready architectures. My work combines strong backend engineering with real-world AI integrations — including LLM-powered workflows, speech-to-text systems, and data-driven automation.

I’ve developed and deployed systems that handle user workflows, AI processing pipelines, and secure data management. From MVP-stage startups to education and productivity platforms, I build backend infrastructures that are designed to be maintainable, scalable, and ready for real users.

On the frontend side, I’ve also delivered complete, client-ready applications using React and modern UI systems, ensuring performance, responsiveness, and clean user experiences.

Here’s what I typically help clients with:
• Building REST APIs using Python (Flask) or Node.js
• Integrating AI/LLM features using OpenAI or Gemini
• Designing backend systems for SaaS and MVP products
• Automating workflows with AI and data processing
• Creating responsive React applications connected to scalable backends

I work remotely with international teams and maintain strong communication and overlapping hours with European time zones. My focus is always on delivering reliable, production-quality solutions that align with business goals — not just writing code.

If you’re looking for a developer who understands both AI capabilities and solid backend engineering, I’d be glad to collaborate.
