• Automate repetitive coding tasks.

• Build MVPs and prototypes in record time.

• Collaborate with Product, UX/UI, and DevOps teams to deliver features end-to-end.

• Integrate APIs, authentication, payments, and external systems (eCommerce, Delivery, POS).

• Write maintainable, scalable, and secure code — even when AI helps you write it.

• Review and guide team members on how to best leverage AI tools in the development process.

• Contribute to setting the AI coding culture — pushing what's possible with human + AI collaboration.

• Familiar with Git, CI/CD pipelines, and cloud deployment (AWS, Vercel, or similar).

• Passionate about productivity, automation, and continuous learning.

Nice to Have

• Experience building or maintaining large-scale systems (SaaS, eCommerce, Delivery, or POS).
