G-01About

I learned this industry from the site up, not the deck down.

I started on site — reading drawings, pouring concrete, correcting formwork that was already half wrong. That is still how I build companies.

I am a civil engineer from Meenambakkam, Chennai. I topped my department at Vels University with a gold medal in B.E. Civil Engineering, and I am now reading for an MBA in Marketing and HR at Hindustan University.

Between those two degrees I spent my time where the work actually happens: as a site engineer running execution, as a design engineer drafting the drawings that execution depends on, as a building auditor, and as a formwork design draftsman. That sequence matters. I have stood on both sides of the drawing — the side that draws it, and the side that has to build it.

Today I run ConnectNBuild, a construction ecosystem incubated at the Vels Innovation Council, and I co-found and operate three other ventures across construction, deep tech, and product. I speak site Tamil and boardroom English, and I have found that most problems in this industry are simply the gap between the two.

A-02Ventures

Four companies. One habit: ship the thing.

I founded one and co-founded three more, across construction, deep tech, and product. Each runs on the same conviction — that operations, not intentions, decide whether an idea survives.

FlagshipJan 2026 — Present

ConnectNBuild

Founder & CEO / Construction ecosystem

A construction ecosystem — incubated at the Vels Innovation Council, Chennai — built to close the distance between the people who need to build and the people who know how.

  • 02Run both the technical and commercial workflows, bridging traditional construction practice with digital scale.
  • 03Grew from a 2024 idea through two years of groundwork to formal incubation in January 2026.

Think Construction, Think ConnectNBuild.

S-03Experience

The road from site engineer to operator.

Read it bottom to top and it is a straight line: execution, then design, then audit, then the commercial side. Nothing here was skipped.

    Sai Sharvesh / various projects

    • Began by managing overall site operations and day-to-day project execution.
    • Moved into design, handling architectural work and complex AutoCAD drafting requirements.
    • Carried execution knowledge into the drawing board — designs shaped by what site can actually deliver.
C-04Projects

Work that left the page and got built.

Three projects I owned end to end — designed, costed, and then actually constructed. The distinction matters more than it should.

01Structural design & execution

Overhead Water Tank, Pammal

Full lifecycle ownership of an overhead water tank for the Pammal area — from structural design through quantity estimation to construction on the ground.

Scope of works

  • Structural design and detailing of the tank and its supporting staging.
  • Quantity take-off and cost estimation for the complete scope.
  • Site execution and supervision through to commissioning.

A single project carried from first sketch to standing structure — design, estimate, and build, all owned end to end.

02Urban infrastructure research & implementation

Pedestrian Level of Service, Post-Pandemic

A study of how social distancing changed the way people use footpaths, and what that means for how wide those footpaths need to be.

Scope of works

  • Measured pedestrian behaviour and spacing patterns after the pandemic reshaped how people walk in public.
  • Calculated the footpath widening required to restore an acceptable level of service at the new spacing.
  • Planned the intervention and saw it through to real-world execution, not just recommendation.

Research that left the paper and became built width on a real street.

03Data-led planning, design & estimation

Public Requirement Analysis & Planning

Collected and analysed data on what the public actually needed built, then took the findings through planning, design, and estimation.

Scope of works

  • Gathered and structured requirement data directly from the people the work would serve.
  • Analysed that data to identify genuine demand rather than assumed demand.
  • Converted the findings into plans, designs, and costed estimates.

Design decisions grounded in evidence about people, not in convention.

G-05Education

Diploma, degree, and now the business half.

Every step was civil engineering until the MBA — and the MBA exists because engineering alone does not tell you how to run the company you end up starting.

Currently

What I’m into right now

Building

ConnectNBuild

Turning the construction ecosystem from a slogan into a working platform, out of the Vels Innovation Council in Chennai.

Studying

MBA — Marketing & HR

At Hindustan University, filling in the commercial and people-side gaps that engineering degrees leave open.

Operating

Three co-founded ventures

Ambianthive, StrataBrains, and Diamond House Construction — deep tech, product, and construction, run in parallel.

Looking for

Co-founder conversations

Startups where an execution-first operator who speaks both engineering and enterprise can move things faster.

G-08Contact

If you are building something, let us talk.

I am open to co-founder conversations, construction partnerships, and consulting work. The fastest way to reach me is email — I answer it myself.

Social presence

Most of what I build in public lives on these channels — the ConnectNBuild academy, the site walkthroughs, and the occasional opinion about how this industry ought to work.

Connect. Build. Scale.
