Building a connected product is hard. It requires expertise across hardware, embedded systems, mobile applications, cloud infrastructure, AI, and the ability to bring all of those pieces together into a production-ready solution.
That's where I help.
I work with startups, scale-ups, and enterprises to architect and build connected products—from embedded devices and IoT platforms to AI-powered mobile applications and scalable cloud infrastructure. Whether you're building a connected vehicle platform, a medical device, an industrial IoT solution, or the next generation of smart products, I can help take it from concept to production.
Over the past 15+ years, I've delivered production software across Connected Vehicles, Telematics, MedTech, Industrial IoT, Transportation, and Enterprise Mobility.
Before founding LogiQlink Technologies, I spent over 12 years at Treeline Interactive in San Diego, progressing from Senior Mobile Engineer to Mobile Tech Lead and eventually Head of India Operations. During that time, I worked directly with US startups and enterprises, leading distributed engineering teams and delivering complex connected products used in production.
Today, as Founder and Director of LogiQlink Technologies, I continue to help companies build connected products by combining deep technical expertise with hands-on engineering leadership.

• React Native and Flutter
• Production mobile applications for connected products, MedTech, transportation, and enterprise platforms
HOW I ENGAGE
Fractional CTO
I help startups define technical strategy, architect scalable platforms, build engineering teams, and make critical technology decisions without the cost of a full-time CTO.
Solution Architect
I design scalable systems from the ground up—including cloud architecture, hardware-software integration, APIs, and connected product platforms—so your team starts with the right technical foundation.
Hands-on Engineer
I still enjoy building products. Whether it's a mobile application, embedded firmware, an IoT platform, or a cloud backend, I write clean, maintainable, production-quality code.
Engineering Leader
I've built and managed distributed engineering teams across the US and India and can help recruit, mentor, and scale engineering organisations for long-term success.
WHO I WORK WITH
• Startups looking for a technical co-founder or Fractional CTO
• Product companies building connected devices and IoT platforms
• Automotive, fleet, and mobility technology companies
• Medical device and digital health companies
• Industrial IoT and enterprise software teams
Whether you need a Fractional CTO, Solution Architect, or hands-on engineer, I bring the technical depth to build production-ready systems and the leadership experience to turn ambitious ideas into successful products. If you're building a connected product, I'd love to discuss how I can help.
