Hello, I'm
PranjwalGupta.
I build production-grade SaaS platforms, distributed systems and AI applications — from Java/Spring Boot microservices and Node.js APIs to RAG-powered agents on AWS. 3+ years turning complex business workflows into fast, secure, scalable products.

I'm a Full Stack Developer and AI Engineer with 3+ years of experience architecting, building and deploying high-performance distributed systems, multi-tenant SaaS platforms and cloud-native applications. I work across two ecosystems — Java / Spring Boot and the MERN stack — and I'm as comfortable designing a Kafka event pipeline or a GraphQL API as I am polishing a React interface.
At DrillMaps I migrated a monolithic application into Spring Boot microservices with an event-driven Apache Kafka pipeline. At Infosware I architected and launched a multi-tenant SaaS CRM with 20+ modules, then scaled it with GraphQL, Redis caching and RabbitMQ, owned its AWS deployments and CI/CD, and led the team through code reviews and intern mentorship.
I'm also a published AI researcher. My M.Tech thesis, Sarthak Companion, is turning a published grief-support framework into a working system built with LangChain, LangGraph, RAG and multi-agent tool calling — technology applied to one of the most human problems there is.
Full-Stack Product Engineering
React, Next.js and Angular interfaces backed by Node.js, NestJS or Java/Spring Boot services — with multi-tenant data models, granular RBAC and secure authentication built in.
Distributed Systems & Microservices
Spring Boot and Spring Cloud microservices, event streaming with Apache Kafka, RabbitMQ queues, Redis caching and GraphQL APIs — built to stay fast and fault-tolerant under load.
Applied AI & Agentic Systems
LLM applications with LangChain and LangGraph, RAG pipelines on Pinecone / Chroma, text embeddings and multi-agent function & tool calling across OpenAI, Gemini and Claude.
Cloud, DevOps & Quality
AWS (EC2, ECS, RDS, S3, Load Balancer), Docker, Jenkins and GitHub Actions CI/CD — backed by JUnit, Mockito, Jest and Cypress, plus code reviews and intern mentoring.
3+ years of shipping to production.
From crafting reusable frontends to architecting a multi-tenant SaaS platform and leading the team that runs it — here's the journey, role by role.
Full Stack Developer
Architected, scaled and deployed a production multi-tenant SaaS CRM — and led the team behind it.
- Architected and launched a production-grade enterprise multi-tenant SaaS CRM with 20+ functional modules, including Sales Pipeline (Kanban), Lead/Task Management, Quotes, Invoices and centralized Email/WhatsApp communication hubs, using React.js, Node.js, PostgreSQL, Prisma ORM and Docker.
- Designed department-wise workflows and role hierarchies with granular RBAC, ensuring complete tenant-level data isolation, secure authentication and cross-module data integrity.
- Optimized backend querying performance by implementing GraphQL APIs, Redis caching for real-time dashboard metrics, and RabbitMQ-based asynchronous processing for heavy notification pipelines.
- Owned end-to-end cloud deployments on AWS (EC2, RDS, S3, Load Balancer) and established fully automated GitHub Actions CI/CD release pipelines.
- Led development efforts across the engineering team: conducted peer code reviews, mentored interns and established strict development workflow standards.
MERN Stack Developer
Built client platforms, admin panels and analytics dashboards for multiple products.
- Engineered frontend modules for VisaLiv, a visa and tour services platform, using React.js, Next.js and Firebase, integrating secure third-party verification APIs.
- Built the Sailax DBC admin panel from scratch, implementing an in-app chat system and analytics dashboards using Next.js, Redux Toolkit and Material UI.
- Implemented TanStack Query for server-state management, data fetching, background refetching and query synchronization across core application modules.
Software Developer (Java & Distributed Systems)
Broke a monolith into Spring Boot microservices and introduced event-driven processing with Kafka.
- Migrated a core monolithic web application into a highly scalable, resilient and fault-tolerant microservices architecture using Java, Spring Boot and Spring Cloud.
- Designed and deployed an event-driven data streaming pipeline using Apache Kafka to handle near real-time message processing and asynchronous background tasks for high-volume operational workloads.
- Developed performant backend microservices using Core Java and Hibernate, enforcing strict test-driven development (TDD) with JUnit and Mockito.
- Optimized relational data models, tuned complex queries and wrote robust transactional stored procedures on PostgreSQL and MySQL.
- Configured and managed cloud-native microservices environments on AWS (EC2, ECS, RDS) with automated deployments via Jenkins pipelines.
Software Engineer
Where my professional journey began — my first role as a Software Engineer.
- Underwent structured engineering onboarding, participating in technical training sessions covering core frontend codebases, responsive design methodologies and strict version control workflows.
- Assisted debugging teams in resolving minor UI rendering bugs and cross-browser alignment issues across internal web modules using JavaScript, HTML5 and CSS3.
Products I've architected & shipped.
