From architecture and team leadership to production AI, I turn legacy liabilities and greenfield ideas into stable, secure systems that hold up at scale. Currently leading engineering for an enterprise platform underpinning a 180,000+ workforce.
Founded and architected a ground-up rebuild of a four-year-old enterprise field-operations system, replacing 195+ flat per-client files with a multi-tenant SaaS where new clients onboard through a web admin panel by configuration, not per-client code. Now serves 50+ client organisations. I made the foundational architecture decisions and directed delivery across backend, web, and mobile with a focused three-person team chosen for deep legacy domain knowledge.
Personally designed and built the platform's first AI capability: a tool-calling agent orchestrated with LangChain.js over GPT-4-turbo, with schema-validated tools wired into live account, project, audit, and role services. Google Gemini powers document OCR and resume-normalisation pipelines, turning manual data handling into structured, automated flows.
Shortlisted at the AWS “AI for Bharat” Hackathon. A voice-first advisory platform delivering AI guidance in Hindi over low-bandwidth networks to farmers in Uttar Pradesh, built to work where connectivity and literacy assumptions break down.
Set technical strategy, make the foundational architecture calls, and de-risk delivery for founders who need senior engineering judgment without a full-time hire.
Architect and build production systems from the ground up (backend, web, and mobile) with the discipline to keep them maintainable as they scale.
Design and ship real AI into products: tool-calling agents, OCR and document pipelines, automation that removes manual work rather than demos that don't ship.
Great Manager Institute recognition, based on direct structured feedback from my team.
Published executive interview on engineering leadership and production-grade AI in large-scale staffing.
Recognised for Piritiya among a wide field of applied-AI submissions.
If you’re building something ambitious, or untangling something that’s outgrown its foundations, I’d be glad to hear about it.
