I am Arif Ali, a full-stack software engineer focused on backend systems, secure applications, automation, and applied AI.

I build secure, production-oriented products with Python, TypeScript, React, Next.js, Node.js, and FastAPI—covering APIs, databases, authentication, automation, and AI-assisted workflows.

Expertise

The areas where I have built substantial, working systems—not just tutorial exercises.

Full-Stack Product Engineering

Building complete applications from responsive interfaces through APIs, databases, authentication, and deployment configuration.

  • React and Next.js product interfaces
  • REST APIs with Node.js, Express, and FastAPI
  • PostgreSQL data models and end-to-end workflows

Backend and Application Security

Designing backend services with clear boundaries, secure identity flows, validation, permissions, and operational safeguards.

  • JWT, OTP, RBAC, TOTP, and refresh-token flows
  • Rate limiting, audit logs, and webhook verification
  • Licensing, device activation, and signed updates

Applied AI and Automation

Connecting language models and Python automation to real product workflows with validation, tools, persistence, and human-readable results.

  • LangGraph tool orchestration and Groq integrations
  • NLP, computer vision, and model experimentation
  • Document, file, and data-processing automation

Testing and Delivery

Packaging projects so another engineer can understand, run, test, and extend them with fewer surprises.

  • Automated tests and GitHub Actions CI
  • Docker Compose development environments
  • API documentation, migrations, and reproducible setup

About

Who I am, what I work on, and the technical areas that interest me most.

I am a full-stack software engineer and B.E. Computer Science graduate who learns by building complete systems. My work spans secure web applications, backend services, offline-first desktop software, automation, and applied AI. I care about clear architecture, practical security, maintainable code, and documentation that helps other engineers run the project. I am immediately available for full-time roles, including remote opportunities in India or worldwide and onsite roles anywhere in India.
