I'm an Engineering Manager and founder with 6+ years building production systems at scale. At Digital Paani, I led the team delivering a real-time IoT platform processing millions of records daily. I'm currently building Qurkle — powered by MIRA, an LLM-based psychometric matching engine built with LangChain, RAG, and vector embeddings in TypeScript/Node.js.

}Hello! I'm Shubham — an Engineering Manager and founder with 6+ years of experience building production systems at scale. I led the engineering team at Digital Paani, delivering a real-time IoT platform for water treatment facilities across India. My technical stack is TypeScript, Node.js, React, AWS, and MongoDB — with recent deep work in LLM systems, LangChain, RAG pipelines, and vector embeddings.
I started my career building EV charging infrastructure at Numocity, moved into full-stack consulting, led development teams at BraynixAI, and eventually became Engineering Manager at Digital Paani — where I built 70%+ of the IoT platform from scratch before leading the team. In February 2025, I founded Qurkle and have been building MIRA — a psychometric matching engine that uses LLMs and vector profiles to understand people at a level far beyond what traditional apps do.

Qurkle
Consumer app powered by MIRA — a psychometric matching engine built on LangChain, RAG, and 74-parameter vector profiles. Rather than matching on surface preferences, MIRA uses LLM-based analysis to understand deep personality signals. Full stack: Flutter (Play Store + PWA), Node.js/TypeScript backend, AWS infrastructure, and real-time notification systems.
Digital Paani
Designed and built 70%+ of the IoT platform from scratch for water treatment facilities — real-time dashboards, bi-directional plant control, ML-based sludge detection, and automated alerting across 40+ plants in India.
Trusted Delivery
Logistics platform for a hyperlocal delivery company — operations dashboards, real-time package tracking, Flutter mobile apps for drivers and agents, MERN stack deployed on AWS with CI/CD pipelines.
Emotional Chatbot
Chatbot integrated with real-time facial emotion detection using OpenCV and PyTorch. Detects user emotion from live camera feed and adapts responses dynamically for a more human-like interaction.
The path so far.
Building MIRA — an LLM-powered psychometric matching engine using LangChain, RAG, and vector embeddings to connect people on deep personality signals rather than surface preferences.
- ▸Built MIRA — an LLM-powered psychometric matching engine using LangChain, RAG, and 74-parameter vector profiles to match users on deep personality signals rather than surface preferences.
- ▸Architected and shipped the full stack: Flutter app (Play Store + PWA), Node.js/TypeScript backend, AWS infrastructure, and real-time notification systems.
- ▸Grew to 420+ screened users, 162 active in Delhi NCR on a lean ₹1.15L marketing budget within the first launch cohort.
- ▸Designed the vector embedding pipeline and sub-100ms similarity search system underpinning real-time matching.
Led and scaled the engineering team delivering a SCADA-like real-time IoT platform for water treatment facilities across India.
- ▸Led and scaled the engineering team — hired, onboarded, and mentored engineers; owned sprint planning, retrospectives, and performance cycles.
- ▸Drove roadmap execution for a SCADA-like real-time IoT platform serving water treatment facilities — bi-directional plant control, configurable alert workflows, automated reporting.
- ▸Shipped ML-based sludge settlement detection sensor using computer vision, delivering operational insights to clients.
- ▸Owned cross-functional alignment between engineering, product, and client teams — translating requirements into technical roadmaps with clear delivery commitments.
- ▸Established CI/CD pipelines, GitHub/Jira workflows, code review standards, and on-call processes from scratch.
Designed and built 70%+ of the IoT platform — real-time dashboards, SCADA-like visualisation, remote equipment control, and multi-channel alert systems.
- ▸Designed and built 70%+ of the IoT platform — real-time dashboards, SCADA-like visualisation with SSE streaming, remote equipment control, and multi-channel alert systems.
- ▸Optimised data ingestion pipelines handling millions of records/day using TypeScript, AWS Lambda, IoT Core, and SQS — achieving a 30% improvement in latency.
- ▸Migrated legacy systems to serverless AWS architecture — Lambda, IoT Core, SQS, CloudWatch — improving scalability and reducing infrastructure cost.
Led two cross-functional teams. Vision SDKs for edge devices. React/Next.js client work. AWS deployments on S3, CloudFront, Lambda. Reduced bug delays by 30%.
- ▸Collaborated with clients to revamp their websites by implementing modern, responsive designs and improving user experience using React.js/Next.js for the frontend and NodeJS with Express for backend functionality.
- ▸Conducted comprehensive SEO optimization for client websites by implementing best practices in meta-tagging, structured data, and performance enhancements to improve search engine rankings and boost website traffic.
- ▸Directed two cross-functional development teams within an Agile Scrum framework, managing daily stand-ups, sprint planning, and retrospectives to ensure team productivity and effective communication.
- ▸Reviewed the codebase extensively, focusing on React components, state management, and API integration to ensure high code quality and compliance with architectural standards.
- ▸Deployed projects on AWS cloud platforms using services like S3, CloudFront, and Lambda to deliver fast, secure, and cost-effective web applications.
- ▸Established and enforced robust development, testing, and release processes, reducing bug-related delays by 30% and significantly improving delivery timelines.
Digitised business processes, preventing ~₹16L/yr losses. MERN stack dashboards, Flutter mobile apps, CI/CD with GitHub Actions, NGINX load balancing.
- ▸Digitised the business processes and prevented losses of approximately 16 lakhs per year by formalising workflows, setting up system checks, and introducing key interventions across various aspects of business operations.
- ▸Designed and developed a comprehensive system with dashboards for operations, marketing, accounts, HR, administration, franchises, distributors, retailers, drivers, delivery agents, and inventory managers, improving efficiency and decision-making.
- ▸Developed and deployed mobile applications using Flutter, enhancing accessibility and usability for various stakeholders.
- ▸Developed management tools and dashboards using the MERN stack and deployed them on AWS, improving system scalability and performance.
- ▸Implemented CI/CD pipelines using GitHub Actions to streamline the deployment process and enhance system reliability.
- ▸Configured and optimized NGINX for load balancing and reverse proxy, improving system performance and security.
- ▸Planned and managed sprints while communicating goals and deliverables to developers, ensuring on-time delivery of the proposed system in adherence to industry standards.
OCPP charger mesh and battery swap solutions for EV brands. Native and hybrid mobile apps with Java, Flutter, and Springboot. MQTT + LoRaWAN IoT integrations.
- ▸Contributed to the development of charging and battery swap solutions for various vehicle brands by creating native and hybrid mobile applications with modern user interfaces along with the backend for the applications, using Flutter, Android Studio, Java, Springboot and SQL.
- ▸Researched and implemented various IoT protocols in the product and developed solutions with MQTT and LoRaWAN.
- ▸Researched and developed a solution for communicating with the IoT device in the charger using Bluetooth and Wi-Fi, resulting in better and more responsive workflow in areas with weak network coverage.
- ▸Designed and implemented understandable architecture, increasing the code's maintainability and testability using the MVVM architecture pattern and writing test cases using JUnit and Mockito.
Graduated. Built a emotional chatbot as the final-year project — also wrote the paper for the same.
