About

I’m a tech leader with 19+ years of experience building and scaling web and mobile platforms, leading high-performing engineering teams, and delivering innovative, AI-powered solutions across domains and geographies. Currently, I lead engineering for Paytm’s agent and distribution ecosystem — powering one of India's largest offline payments networks. My expertise spans front-end and full-stack architecture, AI integrations, large-scale system design, and cross-functional product development. I specialize in crafting scalable platforms that solve real-world problems and enhance user experiences. 🚀 What I’ve Been Building at Paytm: Scaled the Paytm Agent App to enable field agents across India to onboard merchants, manage devices (Soundbox, EDC), and cross-sell services. Developed powerful web-based dashboards and internal tools, including the Merchant Dashboard, Business Site, and onboarding management panels. Led the architecture of AI-powered automations — including: - Multimodal chatbot using LLMs (OpenAI, Gemini), Whisper (STT), LangGraph, and TTS engines. - MCP-driven pipeline to automate crash and bug analysis, reducing engineering load and resolution time. Built and mentored a 50+ member team, including Senior Engineering Managers and Principal Engineers, while driving strategic hiring for future-ready tech talent. 🛠️ Core Strengths: Full-stack product development, architecture for scale, cross-functional leadership, and AI-native engineering. 🌏 Global Product Mindset: My international project exposure has given me a strong grasp of localization, scalability, and user behavior across markets — helping me drive solutions that are as culturally relevant as they are technically robust. 💡 I thrive at the intersection of engineering, product strategy, and people leadership. I bring a builder’s mindset, deep technical hands-on capability, and a relentless focus on impact, scale, and innovation. Let’s connect if you’re passionate about future-ready tech, AI-driven platforms, or scaling high-impact teams. I’m always open to meaningful conversations and collaborations.
