Serial Technology Entrepreneur & Enterprise AI Architect

I have spent more than 24 years moving between code, customers, operations and company building.

My journey began as a software trainer, then as a software developer working on ATM monitoring systems, before moving into enterprise account management at IBM. Those early roles taught me how technology is built, how it is sold and, more importantly, how it is judged in the real world.

My entrepreneurial journey began in 2008 with an industrial automation product for the deinking plant of a recycled-paper mill. I had to understand the process, translate plant operations into system logic and work within founder-funded constraints.

That experience taught me that software succeeds only when it fits the machinery, people, economics and operating reality around it.

I later co-founded ATExpert I Services and served as CTO, leading product planning, architecture, engineering and early customer acquisition.

In 2012, I began my sole-founder journey through Sastra Services. Since then, I have delivered software solutions and services to nearly 350 clients across international markets while carrying responsibilities that usually sit across several leadership roles: sales, discovery, pricing, architecture, engineering, talent, delivery, financial oversight and client relationships.

My philosophy is simple:

Innovation is not novelty for its own sake. It is seeing an existing problem differently, combining proven capabilities intelligently and creating meaningful value.

Alongside services, I built a series of products through Sastra Services. Each one added to my understanding of markets, users, economics and product judgment.

Learning When Not to Reinvest

iSkool, iHMS and SastraQ addressed school administration, hospital operations and patient-flow management.

They recovered their development and maintenance costs, but we had entered mature markets late. Taking them further required major modernization and reinvestment without an attractive enough return.

They taught me that a technically successful and break-even product can still lack a compelling future investment case.

Learning That Traction Is Not Sustainability

PaperDabba began as a digital news portal and grew into a YouTube channel with about 25,000 subscribers.

The audience grew, but the production economics did not. We could not optimise the cost of consistently producing quality content, and Sastra needed to prioritise Medha, MedhaOS and SastraPDF.

I paused PaperDabba at the end of 2024. It remains paused, not retired.

It taught me that traction and sustainability are not the same.

Discovering a Deeper Problem

Jobzfi.com is a long-term Sastra recruitment product.

Its first version operated from 2018 to 2022 and did not reach commercial break-even, but it exposed a deeper problem: conventional applicant-tracking systems often reduce people to keywords, reward résumé formatting over capability and miss transferable skills.

Those lessons led to the Anti-ATS model within Medha.

Jobzfi will return as a stronger product built around contextual, capability-based and explainable matching.

Learning the Importance of Grounding

Flashbot, operated from 2020 to 2022, was a website chatbot that answered only from the connected website’s content using Google’s neural-language capabilities.

It gave me early experience with grounded conversational systems and controlled knowledge boundaries.

The lesson remains central to my work today: conversational fluency is not enough; useful AI must stay grounded in authorised information.

Building for Purpose

Quizerrr was built during COVID as a fun learning-from-home application for children and adults. It used quizzes, contests, battles, coins and rewards.

It was not intended to become an EdTech business. It served a specific purpose and ended when that purpose was fulfilled.

It taught me that not every useful product needs to become a permanent commercial venture.

Building Sastra Innovations

Today, I lead Sastra Innovations as Founder & CEO and hands-on Chief Technology & AI Architect.

  • Medha is our proprietary persistent reasoning and governed-execution engine.
  • SastraPDF is Medha’s first commercial application, focused on document intelligence and workflow execution with more than 70 document operations.
  • MedhaOS makes Medha governable and deployable inside enterprises through identity, permissions, tenant isolation, policies, approvals, auditability, sensitive-data controls and private or hybrid deployment.

Alongside product development, I lead selective engagements involving custom applications, workflow automation, API integration, application modernization, document intelligence and AI-enabled enterprise software.

The systems I build today are not a departure from my earlier journey.

They are the accumulated result of years spent learning when to build, when to reinvest, when to pause and when a deeper problem deserves an entirely new architecture.
