I build AI web apps and APIs that ship fast and hold up in production. Startups hire me for SaaS MVPs and LLM features. I steady shaky systems into reliable platforms.
I'm Krimaben Desai, a Senior Full-Stack AI Engineer with 9+ years across SaaS products and data-heavy web apps. I deliver maintainable code and clean handoffs.
React with TypeScript for frontends. Python with FastAPI for REST. PostgreSQL or MongoDB for storage. AWS deploys with Docker and Kubernetes. CI/CD from day one. OpenAPI docs and tests included.
I ship practical LLM features, not demos. RAG pipelines wired to PDFs and private knowledge bases. Vector stores on Pinecone or Weaviate. Chat assistants and document Q&A with contextual retrieval. LangChain with OpenAI models. I handle embeddings, prompt checks, response monitoring, structured outputs, auth and rate limits, so answers stay grounded.
For growth I plan caching, background jobs, pagination, rate limits. Versioned APIs and clear migrations keep upgrades painless.
On Upwork, 22,000+ hours and $300K+ earned through long partnerships. Top Rated Plus with steady 5 star feedback across US, UK, EU, AU and APAC.
What I can help with:
- Ship a SaaS MVP fast. React with TypeScript on the front. FastAPI on the back. PostgreSQL or MongoDB for data.
- AI features, from chat assistants to doc Q&A with RAG.
- FastAPI backends with clean REST and versioning. OpenAPI docs included.
- Multi tenant auth and roles. Add audit trails.
- AWS deployment with Docker and Kubernetes. CI/CD set up.
How I work:
- Short discovery, then scope and milestones you can sign off.
- Prototype or API spec in 48 to 72 hours for most projects.
- Weekly demos. Tight feedback loops.
- Clean Git history with clear commits and branches.
- CI/CD, logging, metrics and alerts before launch. Handover docs and runbooks.
I'm available for AI feature integration and SaaS MVPs. Backend architecture and long term product work with US or EU overlap. Message me to plan the first milestone.

Hi, I’m a Full Stack AI Engineer with strong experience in building AI agents, RAG systems, SaaS platforms, admin dashboards, API integrations, automation workflows, and scalable full-stack web applications.
I work across React, Next.js, Node.js, NestJS, Python, Ruby on Rails, MongoDB, PostgreSQL, LangChain, n8n, MCP, and LLM-based systems. My focus is not only writing code, but building production-ready systems that solve real business problems.
Recently, I completed AI and full-stack projects including:
* AI Developer for Generative & Agentic AI Projects
* Built AI workflows using LangChain, RAG, MCP, and agentic AI patterns. The client rated the work 5.0 and mentioned solid AI skills, on-time delivery, and quality code.
MERN Admin Dashboard:
* Developed a full-stack admin dashboard using React, Node.js, and MongoDB. The work involved clean frontend implementation, backend APIs, dashboard logic, and strong communication throughout the project.
Complex Ruby / Full Stack Web App:
* Worked for more than a year on a complex legacy web application involving Ruby, JavaScript, CSS, dashboards, recordings, media features, frontend redesign, and feature improvements.
Currently, I am also working on:
* Multi-agent Genkit framework for agentic backbone setup
* Backend development for crypto payments and API integrations
* Senior Ruby on Rails development with 3,000+ hours logged
* MVP booking platform with functional APIs and product workflows
I can help you with:
* AI agent development
* RAG and LLM integration
* LangChain and MCP-based workflows
* OpenAI and Claude API integration
* n8n automation workflows
* SaaS platform development
* MVP development
* React and Next.js frontend development
* Node.js, NestJS, and Express backend development
* Ruby on Rails development
* API architecture and third-party integrations
* Admin dashboards and internal tools
* FinTech and payment-related backend systems
* DevOps support and deployment workflows
What makes me different is that I understand both product delivery and technical execution. I can take a loose idea, convert it into a working plan, build the frontend and backend, integrate AI or automation where needed, and ship clean, maintainable code.
If you need someone who can build AI-powered SaaS products, automate business workflows, improve an existing codebase, or develop a full-stack platform from scratch, I can help you move faster with the right technical direction.

Full Stack Developer with 15 years of experience and Team Lead delivering 300+ projects - your trusted long-term development and solution architecture partner specializing in Vue.js, React, and Node.js
The code is invisible; the outcome is not
With me:
- Autobound grew from one engineer to a 25-person team through 7+ years of our cooperation, raised more than $12M in funding, scaled to 50K+ active users and $8M ARR along the way.
- DriverHRIS evolved from a slow 1000-screen system into a fully rebuilt product serving 400+ dealerships, backed by an 18-person dev team, over 5+ years - page loads dropped 80%, support tickets cut in half.
- Augmento expanded from a prototype to a 15-person dev team in 3 years, powering AR experiences for 30+ global brands including Fortune 500 companies and securing $6M in investment.
At Wawibox (Germany, dental-industry SaaS), I've led the engineering team for 8+ years - owning the full rewrite of the legacy Vue 2 platform into a modern Vue 3 / Nuxt 3 / Node.js / TypeScript / PostgreSQL stack without a single day of downtime for 2,000+ paying clinics across 3 countries.
Over 12 years of strong experience building AI-powered SaaS products, ecommerce platforms, fintech systems, and marketplace applications. Proficient in React, Next.js, Python, PHP, Laravel, and cloud infrastructure on AWS. 200+ clients served, 98% delivery rate on time and budget.
I'm also an early and heavy Claude power-user - AI-assisted development is part of how I ship, not a novelty bolted on.
Cursor, Claude Code, agentic workflows, LLM integrations in production - I've been living in this stack since the day it existed.
Got a product to build, scale, or rescue?
Whether it's a new build, a team extension, or a legacy system that's slowing you down - message me and let's find a solution that actually fits your situation.
The first 30 minutes are on me, and you'll walk away with a clear next step either way. 🚀

I am a Java developer with over 14 years of experience building full stack applications, enterprise systems, and SaaS platforms 🚀
My focus 🎯 is on using Java, Spring Boot, React.js, PostgreSQL, and AWS to deliver reliable, scalable software. As a Java developer, I have delivered dozens of projects across industries and use cases.
My backend work is built entirely with Java. I create secure APIs and microservices using Spring Boot. I have deep experience in system architecture, backend performance, and database design. Every project I take as a Java developer is written with clean, maintainable Java code. I know how to structure services that scale.
As a Java backend developer, I have built and maintained systems for high-load traffic, third-party integrations, and complex business logic. I manage full backend pipelines, from architecture and development to deployment and monitoring. I use Spring Boot and follow best practices every Java developer should apply.
I also work as a full stack Java developer, connecting Java backends with React.js and JavaScript frontends. I create dashboards, user interfaces, and admin tools that are fast, stable, and fully integrated. I know how to deliver full stack features without bottlenecks.
I have led teams as a senior Java developer, mentoring other developers, reviewing Java code, and improving team performance. My clients rely on me not just for development, but also for decisions about architecture, data structure, and deployment strategy. As a Java developer, I care about the full picture.
In most projects, I take the role of a Java spring developer and own the backend infrastructure. I work with Docker, PostgreSQL, REST APIs, and cloud services. I often work independently, taking full responsibility for both backend and frontend parts as a full stack developer.
Being a professional Java developer means I deliver production-ready code, meet deadlines, and communicate clearly. I work well with teams or as a solo contributor. My background as a Java backend developer and Java spring developer allows me to adapt to different project needs.
If you need a Java developer who can work on backend systems, full stack features, or cloud-based platforms, I am ready to help. Whether you need a senior Java developer, a Java backend developer, or a reliable full stack Java developer, I can take your project from idea to production.
🛠️ Core Skills:
- Java developer
- Java backend developer
- Full stack Java developer
- Java spring developer
- Spring Boot microservices
- React.js and JavaScript
- PostgreSQL, AWS, Docker
Let’s talk if you need a results-driven Java developer to join your team or take over delivery.

Businesses don't hire developers — they hire outcomes. In 5+ years of
full-stack development, I've helped startups, agencies, and growing
companies ship faster, integrate smarter, and scale without breaking.
I specialise in Laravel and Node.js backends paired with Vue.js, Next.js,
and Nuxt.js frontends — building applications that handle real traffic,
real transactions, and real business logic.
Whether you need a secure REST API, a payment system wired to Stripe,
Razorpay, or PayPal, a web scraper that extracts thousands of records
daily, or a SaaS platform built to grow — I've built it, maintained it,
and handed it off with clean documentation.
What you get when you work with me:
→ Laravel & Node.js APIs — authentication, roles, complex business logic,
and optimised queries across MySQL, PostgreSQL, and MongoDB
→ Full-stack SPAs using Vue.js, Inertia.js, React.js, Next.js, and
Nuxt.js with clean state management and pixel-perfect interfaces
→ Payment gateway integrations — Stripe, PayPal, Razorpay, Chargebee,
Recurly, Mollie — subscriptions, webhooks, and refund flows done right
→ Python automation and web scraping — Scrapy and Selenium pipelines
that extract, transform, and deliver data reliably at scale
→ Cloud deployment on AWS (EC2, S3, RDS), DigitalOcean, and VPS with
Docker and CI/CD pipelines that keep releases smooth
→ Third-party API integrations — Twilio, Mailgun, Google Maps, and
custom connectors built to stay stable long after delivery
I don't disappear after delivery. I write code that your next developer
can read, maintain, and extend without calling me to explain it.
Clear communication. Honest timelines. Zero surprises.
