Consulting: Guided UAT Setup Walkthrough (Supabase + Stripe + Vercel)
Jaimish successfully walked me through the deployment of a web app involving supabase, Vercel and Stripe. He guided me through the process as I shared my screen. Jaimish was very patient the whole time. The app was deployed to UAT and he provided notes that covered all the steps we took and that will help me deploy the app to production. When issues arose he was able to troubleshoot them quickly and keep us on track. I highly recommend Jaimish and I intend to work with him again should there be a need. Thanks Jaimish!

Job Success
Mumbai, India - 1:57 am local time
I build in React, Next.js, Nest.js and Node.js, and these days most of it is AI SaaS. Top Rated Plus here, 97% Job Success, 7,400 hours, 28 jobs done. This year I shipped a voice agent platform, a B2B sales automation SaaS, and a geo-grid rank tracker.
People usually come to me for one of three reasons.
1 )They want an MVP live without regretting the code six months later.
2 ) They inherited a half-finished build from a team that walked away.
3 ) Or the product demos fine and falls over the moment real users hit it.
Across those 7 years as a Full Stack Developer I have delivered 50+ applications and integrated 1000+ APIs for startups, founders and growing businesses.
WHAT I BUILD AS A FULL STACK DEVELOPER
SaaS Platforms and Web Products
• Multi-tenant SaaS with tenant isolation, roles, permissions and subscription billing
• Customer portals, admin dashboards, internal tools and B2B marketplaces
• React and Next.js frontends with clean, maintainable component architecture
• Nest.js and Node.js backends built for performance and scale
• MVP development for founders who need to launch and validate quickly
AI Development That Holds Up in Production
As an AI Full Stack Developer I ship AI features that survive real users, not just demos.
• AI chatbots, support agents and voice agents
• RAG systems over your own documents, PDFs and databases
• AI agents and multi-step LLM workflows
• Claude API, Anthropic, OpenAI and GPT integrations
• Vector databases, embeddings and semantic search
• AI automation for sales, support and internal operations
Automation and System Design
• Background jobs, schedulers and queues
• Event-driven architecture, caching and rate limiting
• Webhooks, cron pipelines and n8n workflow automation
• API-first design that scales cleanly across services
Cloud and Production Readiness
• AWS including EC2, S3, RDS, Lambda and CloudFront
• Dockerized deployments with CI/CD pipelines
• Vercel, Railway and DigitalOcean deployments
• Monitoring, high availability, backups and cost optimization
Security and Integrations
• Authentication and authorization with JWT, OAuth2, SSO and RBAC
• Stripe subscriptions, billing portals and payment gateway integration
• CRM, ERP, HubSpot, Salesforce, analytics and third-party API integrations
• REST APIs and GraphQL APIs built to scale
MY STACK

• Backend: Nest.js, Node.js, Express, Python, Laravel and scalable service architecture
• Databases: PostgreSQL, MySQL, SQLite, MongoDB, Supabase, Realm Database, Prisma and Redis
• AI: Claude API, Anthropic, OpenAI, LangChain, RAG, vector databases and prompt engineering
• APIs: REST APIs, GraphQL APIs, webhooks and third-party integrations
• Infrastructure: AWS, Vercel, Docker, CI/CD pipelines and cloud deployments
• Mobile: React Native for cross-platform apps connected to SaaS backends
• Product Focus: Scalability, security, maintainability and clean architecture
INDUSTRIES I HAVE SHIPPED IN
Healthcare, Real Estate and PropTech, EdTech, Logistics and Supply Chain, Warehouse Management, Hospitality and Booking, Construction and Field Service, Ecommerce and Marketplaces, Fitness and Wellness, CRM, ERP and business automation.
HOW I WORK
A Full Stack Developer who only closes tickets will cost you more than one who thinks about the product. I ask the hard questions in week one, not month three. I flag scope and architecture risks before they turn into rewrites. And I write code the next developer can actually maintain, which is why several of my contracts have run for over a year.
• 7 years of experience, Top Rated Plus, 97% Job Success across 28 contracts
• Response in 0 to 4 hours, with overlap into US, UK and Australia working hours
• Clear weekly updates, honest timelines, no surprise scope
• Long-term product mindset, not task-by-task delivery
The best work I have done started with a call where I told the client their plan was too big. Cutting scope early saves more budget than fast typing ever will.
BOOK A CONSULTATION FIRST
Not ready for a full build yet? Book a 30 minute consultation. I will look at your architecture, stack and scope and give you a straight answer on what it should cost and how long it should take. Most people leave that call with a clearer plan whether or not we end up working together.
If you want a Full Stack Developer who can own the whole product, from architecture through to deployment, send me a message with what you are building. I will tell you honestly whether I am the right fit.
