Buzzlinc

Founder

Sep 2025Present · 9 mos · Remote

  • Like most founders, I didn’t struggle because the product was bad — I struggled because of my marketing where generating consistent leads was painful, fragmented, and expensive. Too many tools. Too much setup. Too little return.
  • I built BuzzLinc because I needed it myself.
  • I code the product, design the growth systems, and use it daily to generate leads, run campaigns, and turn ideas into content — without a marketing team. Everything in BuzzLinc is shaped by real founder problems: broken funnels, inconsistent outreach, and tools that overpromise and underdeliver.
  • BuzzLinc is built by a founder, for founders — to help you generate leads, capture attention, and grow faster with AI doing the heavy lifting.

Udemy Instructor - AWS Ninja

Jun 2020Aug 2022 · 2 yrs 2 mos · Delhi, India

  • Instructor for AWS Ninja course on udemy.
  • https://www.udemy.com/course/aws-ninja
  • A unique course that teaches AWS in a practical project based manner. It's not a certification course. It's for builders, entrepreneur and developers who want to build their own products and understand AWS products by building something. Their are thousand of courses on AWS but none teaches the student in a practical project based manner and cover end to end lifecycle of a cloud application. Students spend money after money and pay for courses to get these skills. This course is a complete bootcamp that turns student into AWS Ninja. Say no to buying more and more courses. Every latest aspect of cloud services will be covered in this course. Best part the course will be updated with new content and services for lifetime. So no more searching for a course that cover few AWS services. Join and become an AWS Ninja.
  • When i started building my own products as part of www.yogafire.guru i found  the limitation of courses that are offered on various websites. As an entrepreneur it was a frustrating experience to buy courses after courses and none covering how to make a product from end to end. This course is an attempt to fill that gap. Hope you enjoy the same.
  • Who this course is for:
  • Developers who have 1-2 years of AWS or Coding experience
  • Beginners Who Want To Understand Industry Buzz Words Serverless, Alexa, Big Data, Machine Learning
  • Entrepreneur and Builders Who Are Tired Of Buying Courses After Courses
  • Anyone Who Wants To Learn AWS In A Practical Way
