👋 Hi, my name is

Ujjwal Kirti.

I build async-first web applications 🌐

I build scalable full-stack applications, design distributed systems, and architect cloud-native solutions for reliability and performance.
Currently, I'm diving deeper into distributed systems and using LLMs to build smarter, more efficient applications.

Let's connect!

01. About Me

I love building and optimizing systems that power the internet.
Lately, I've been focused on distributed systems and cloud architecture, exploring microservices, scalable backend solutions, and modern web technologies.
My goal is to create robust, high-performance applications that deliver exceptional user experiences.

My Educational Background:

  • Latest Education: Graduate
  • Degree: Bachelors of Technology
  • Major: Civil Engineering
  • Institute: National Institute of Technology, Surat (SVNIT) link
  • Duration: 2019-2023

02. Experience

  1. Full Stack Developer · Freelance

    06/2024 — Present
    • Architected and scaled modular REST APIs using Express.js, PostgreSQL, and Sequelize across Auth, CMS, Syllabus, Analytics, and PYQs services; implemented JWT + RBAC and async processing via RabbitMQ/PubSub, reducing latency by 40% and serving 100K+ users.Link
    • Built an AI-powered storytelling platform with Next.js that generates personalized stories using generative models to enhance student and educator engagement.Link
    • Optimized infrastructure with bare-metal (Docker + Nginx) for development and Azure (GitHub Actions → ACR → Container Apps + Front Door) for production, achieving 99.9% uptime, zero-downtime releases, and 30% cost reduction.
    • Designed commit-based CI/CD pipelines with PR preview environments via reverse-proxy routing; reduced deployment time by 60%, production regressions by 30%, eliminated manual errors, and saved thousands annually.Link
    • Developed a generative-AI Chrome extension that converts webpages into structured flashcards, adopted by students across 20+ universities.Link
    • Built a community-driven blogging platform using a GitHub PR workflow (inspired by Hugging Face), enabling scalable content contributions and streamlined editorial review.Link
    • A communication toolkit (for neurodivergent and autistic individuals) that breaks down ambiguous language, explains idioms, and provides social context—helping everyone understand and respond with confidence.Link

  2. Full Stack Developer · Root On Immigrations

    07/2022 - 05/2024
    • Designed and developed a cloud-native, scalable immigration services platform using Next.js (App Router), TypeScript, TailwindCSS, Material UI, and FastAPI, delivering a seamless experience to thousands of users with >95% Lighthouse scores across devices.Link
    • Architected a hybrid multi-cloud deployment strategy, hosting production workloads on AWS EC2 and optimizing development environments with Vercel (frontend) and Google Cloud Run (Dockerized backend), resulting in a 40% improvement in load times and a 25% reduction in cloud costs.
    • Integrated global payment systems (Stripe, Razorpay) with domain-specific flows, boosting successful transactions by 30% and cutting payment failures by 20% through enhanced backend resilience and payment orchestration.Link
    • Engineered platform accelerators like a Course Recommendation System, SOP/SOWP builders, and a paid RAG-based chatbot, increasing customer engagement by 50% and raising satisfaction scores by 15%.Link
    • Built a modular backend architecture to scalably support 26+ immigration service domains, and implemented Infrastructure-as-Code (IaC) practices to streamline service orchestration, boosting deployment speed and maintainability.
    • Developed and deployed a custom Chrome Extension to automate counselor-client communication workflows, saving 20+ hours per week and increasing operational efficiency by 35%.
    • Enhanced SEO, accessibility, and performance through React Server Components, dynamic sitemap generation, and server-side optimizations, achieving 35% higher organic visibility and 25% faster server response times.
