About Lynky Tech

Lynky Tech builds done-for-you AI automation systems and AI-first platforms for businesses across India and the UAE, from jewellery and manufacturing to real estate and services.

We work on clearly scoped, fixed-timeline engagements that deliver real value in weeks, not quarters. We are a small, founder-led team, so you will work directly with the founder from day one.

About the Role

You will build and deliver mobile applications for real clients across jewellery, manufacturing, education and real estate.

The role involves developing cross-platform mobile applications using React Native or Flutter, along with the backend systems that support them.

You will use AI coding tools such as Claude Code every day. You are responsible for reviewing, testing and understanding everything you build before it is delivered.

You will work directly with the founder from our R.S. Puram, Coimbatore office.

A Typical Day

- Develop or fix backend APIs, database queries, WhatsApp integrations and payment integrations.

- Test builds on real mobile devices and fix issues.

- Share test builds with the project coordinator or client.

- Prepare releases, including building, signing, uploading and tracking store or client feedback.

Key Responsibilities

- Build mobile applications using React Native or Flutter for Android and iOS, from requirements to Play Store and App Store release.

- Implement authentication features such as OTP/password login, user roles and secure payment gateway integrations.

- Integrate WhatsApp Business API workflows, notifications, voice input and calling features.

- Build AI-powered features within applications, including LLM integrations, voice assistants and simple AI agents.

- Deploy and maintain production backends, manage environments, monitor applications and resolve post-launch issues.

- Work with the project coordinator, participate in client demonstrations when required and document technical workflows.

- Review all AI-generated code, test applications on real devices and ensure that everything delivered is properly understood and tested.
