Embedded leadership, not light consulting. I build with your team — from AI strategy and platform modernization to security compliance — so you ship faster, reduce risk, and scale with confidence.
Who I Work With
What We Do
We don't sell generic "digital transformation." We embed at the leadership level and deliver across the full stack — AI systems, platform architecture, security posture, and org execution. Every engagement is anchored in outcomes, not activity.
Move past pilots. We architect production-grade agentic workflows, multi-agent orchestration pipelines, and LLM-native applications that ship and scale — not just demo. Including AI-built codebases that compress development timelines by orders of magnitude.
Legacy architecture is a tax compounding daily. We re-architect monoliths into cloud-native, API-first, microservices platforms — with zero-downtime delivery, PDLC rigor, and measurable velocity gains from sprint one. Transformation, not just migration.
Enterprise trust is earned through architecture, not assertions. We lead ISO 27001/27701, SOC 2, and GDPR readiness end-to-end — treating governance, risk, and compliance as a first-class capability built into the platform, not bolted on after.
Senior technology leadership — deeply embedded, not lightly consulted. We partner with founders, boards, and investors to convert ambiguous goals into executable strategy: org design, senior hiring, technical roadmaps, and delivery velocity that compounds.
Measured Outcomes
We don't trade in vague transformation promises. Every engagement is anchored in measurable engineering and business outcomes — delivered across fintech, EdTech, mobility, and enterprise platforms serving millions of users across three continents.

Selected Work
Led full platform modernization for a global AI-driven language learning app. Zero-downtime Classic→Nova migration, agentic conversation modules deployed across 60+ languages, ISO 27001/SOC 2/GDPR readiness, and 100% critical vulnerability resolution.
Built a cloud-native, API-driven originations platform processing 200k+ daily transactions. Launched HDFC Payzapp, integrated 5 major banks and 18 fintech clients. ML-driven fraud system with rule-based and AI-hybrid architecture slashed losses by 80%.
Scaled in-car AI and IoT platform to 50,000+ vehicles across 7 Indian cities on Microsoft Azure. 10M events/minute — driver scoring, predictive maintenance, telematics, and contextual content delivery via microservices architecture.
Co-architected a multi-agent orchestration system that generated ~95% of Genspark's production codebase — in under 5 months. Emotionally aware AI tutoring, personalized content delivery, proactive learner engagement, and plugin-based generative content architecture.
Architected and deployed a full omnichannel retail platform in under 6 months — 60 microservices, API gateway, AI-driven analytics, 30+ global brands across 600+ stores. 35% customer satisfaction rise, 40% fewer post-release defects.
Designed core SaaS architecture for FICO Falcon Fraud Manager and Blaze Advisor — AI/ML fraud detection across credit, debit, prepaid, and digital payment channels. Built multi-tenant data access layer with encryption, audit logs, and schema upgrade controls.
What Founders & Operators Say
I've worked with consultants who give you frameworks and disappear. Ambuj joined our standup on day two. By month three, our AI conversation engine was in production across twelve new languages and our DAU/MAU ratio had moved in a way we hadn't managed in two years of trying internally.
Co-founder, AI language-learning platform · 200k+ weekly active learnersWe were processing half a million transactions a day and our fraud stack was held together with duct tape. He mapped the gaps in a week and delivered a hybrid ML + rules engine in under three months. Losses dropped materially. The board noticed.
CTO, Series B neo-banking platform · $500M+ in annual payment volumeWe wanted a genuinely AI-native codebase — not AI-assisted, but AI-built. He co-designed the multi-agent orchestration pipeline and within five months we had a production system that investors called the most technically ambitious thing they'd seen at our stage.
Co-founder, agentic AI platform · seed-funded, San FranciscoOur SOC 2 audit was blocking two enterprise deals worth over $2M combined. Ambuj mapped every control gap, embedded with the engineering team, and had us audit-ready in fourteen weeks — without a single sprint being interrupted. I cannot overstate how rare that combination is.
VP Engineering, B2B SaaS · Fortune 500 customer baseScaling tens of thousands of connected hardware units is a completely different challenge from pure SaaS. He understood the IoT edge, the cloud telemetry layer, and the product experience tying them together — and he moved fast. Exactly what you need at Series A when you're still figuring things out.
Head of Engineering, B2B mobility platform · 40,000+ connected units deployedSix months to stand up a full omnichannel retail platform felt like an impossible ask. He architected the microservices layer, brought delivery rigor we simply didn't have, and we launched on schedule. Adding a new brand is now a day's work, not a quarter's.
CTO, omnichannel retail company · 30+ brands across 600+ storesOur fraud detection was built for a different era. He redesigned the data access architecture, introduced ML-native decision scoring, and the system passed every load test on day one. Deep technical judgment paired with real commercial awareness — that combination is genuinely hard to find.
Chief Architect, enterprise fraud intelligence SaaS · global banking deploymentsI was a solo technical founder, pre-revenue, trying to prioritize what to build first. One conversation with Ambuj gave me more clarity than months of reading and networking. He sees the full stack — product, architecture, team, GTM — and he's completely direct about where you're weak.

The Principal
I'm an engineer who grew into a technology leader — and never stopped building. Over 25+ years across Ola, Zeta India, and ELSA Corp, I've scaled platforms to tens of millions of users, built fraud intelligence systems that cut losses by 80%, and led AI integrations that actually ship into production.
At White Lotus Labs, I work as a Fractional CTO and AI strategy partner — embedded deeply, not lightly consulted. My edge is the combination of architectural depth, production experience with agentic AI at scale, and the hard-won ability to build and lead high-performing engineering organizations. I co-founded SaaSyAI and Genspark, where we engineered ~95% of the production codebase using agentic AI pipelines — a live proof of what becomes possible when you adopt a genuinely AI-native mindset.
I advise Y-Combinator founders on technical architecture and AI strategy, serve as Secretary General of the Council of Fractional CXOs, and bring a rare combination of GRC depth, platform modernization experience, and hands-on agentic AI expertise to every engagement.
