Engineer, builder, and pattern recogniser.

I help founders and operators turn hard problems into shipped systems — architecture, scaling, agentic AI integration, zero-to-one product, and the operating discipline to keep building while you lead.

Most engagements start as a soundboard, become an audit, and convert into either an engineering build or a product license. The shape follows the problem.

WHAT I DO

Three modes. One engine. Choose the lever you need.

Most engagements start as a soundboard, become an audit, and convert into either an engineering build or a product license. The shape follows the problem; the substrate stays the same.

MODE 1

Fractional & advisory

Sit alongside your leadership team for a defined window. Soundboard, audits, board-case prototyping, transformation oversight. Senior judgement plus an agentic substrate that does the analyst work in days, not months.

See engagements
MODE 2

Engineering services

Tiny teams of two-to-three plus agents-of-agents. Audits to architecture to delivery. Same wire-end as ThoughtWorks-grade discipline, expressed through agentic workflows.

MODE 3

Products (Breathworks)

Cockpits and Companions. The engine I've been building for twelve years, now a Pvt Ltd. GruWorks for solopreneurs and SMEs; Yoga and Dharma Companions for the NGO; a Founder / Builder Assistant in incubation.

CAPABILITIES

Five axes. One engine.

The shape underneath the work — what makes a Cockpit a Cockpit and an audit an audit. Each axis has been compounded over a real project; each is a place I'd be glad to work with you.

Architecture & systems design

Engine-of-engines. Multi-face product strategy. Federated systems where one substrate serves many surfaces.

An engine for a Bay-Area billionaire — real-time matchmaking surface where multiple brands compete for one demography. London, 2010.

Scaling engineering organisations

ThoughtWorks-lineage discipline applied to legacy modernisation. From cluttered to coherent — by reshaping team boundaries, not just code.

Four years inside Swiggy: leading the org-shape transformation from an over-populated engineering team to a leaner, sharper model.

Agentic AI integration

Cockpits, Companions, and the underlying judgment substrate. Frontier models channelled through human-in-the-loop architecture.

An executive coach in San Francisco — built her into a marketplace platform with 500 wisdom-skills and 100 active CXO users.

Zero-to-one product

From problem-domain to thinnest vertical slice. Then milestones, features, acceptance criteria, audits — the whole craft.

An X-large fin-bank in India — first end-to-end neo-bank, half-a-billion thesis. L5 to L13 implementation, founder-funded by a Flipkart billionaire.

Founder operations

How to stay technical while running a Pvt Ltd. Tiny-team-plus-agents discipline. Decision sequencing for the founder who refuses to vanish into management.

An SF crypto CTO — anonymous-wallet underwriting MVP shipped in 21 days against a planned six-month timeline.

SELECTED WORK

Anonymised — but not abstract.

The ThoughtWorks convention: clients are described by archetype, not by name. Every case below is a real engagement. I'll walk through any one of them on a call.

ZERO-TO-ONE · BFSI

First end-to-end neo-bank in India

Half-a-billion-dollar thesis, founded by a Flipkart billionaire. Took the user-journey from L5 (Ernst & Young handoff) to L13 implementation and run.

L5 → L13 in <1 yr
SCALING · LAST-MILE

Org-shape transformation inside one of India's two food-delivery duopolists

Four-year engagement helping leadership re-shape a cluttered engineering organisation into a leaner, more effective model. The shape of the team became the shape of the system.

ARCHITECTURE · MARKETPLACES

Engine-of-engines for a Bay-Area billionaire

Real-time matchmaking surface where multiple brands compete for one demography. London, 2010. The early ancestor of every multi-face product I've built since.

Leadership platform for a senior executive coach

Six-month build with a YouTube / Google / LinkedIn product veteran. Course content + 24/7 assistance + 500 wisdom-skills. 100 CXO users in San Francisco.

CONSULTING

Four tiers. Honest ranges. Talk to me about your case.

The list isn't a menu — it's the shape of how engagements typically start. Most begin in tier one or two and earn their way into tier three.

TIER 1

Soundboard

A defined window for hard thinking. We talk; I bring the agentic substrate; you walk out with a sharper picture. Best when you're deciding whether you have a problem at all.

1–3 sessions · 90 min each₹50K – ₹2 L / session
TIER 2

Audit / Lighthouse

An exploratory deep-dive — engineering, organisation, vendor, product, or strategic. You leave with a tangible artefact: a digital twin, a vendor scorecard, a board memo, or a prototype of the path forward.

4–6 weeks · senior judgement + agentic team₹15 L – ₹50 L
TIER 3

Engagement / Build

Audit converts to delivery. Tiny teams, agentic harnesses, ThoughtWorks-grade craft. Either as a fixed-scope build or a milestone-priced phased programme.

12 weeks – multi-quarter₹50 L – ₹3 Cr+
TIER 4

Fractional advisor seat

Monthly retainer for ongoing access — soundboard cadence + ad-hoc pulls + agentic substrate available between sessions. By referral.
