𝗔𝗩𝗔𝗜𝗟𝗔𝗕𝗟𝗘 𝗧𝗢 𝗦𝗧𝗔𝗥𝗧 | ⭐ Top Rated Plus Full Stack Developer | 💰 $200K+ Earned on Upwork | 182 Jobs | 12,148+ Hours
Hello, I'm Sarbjeet, a Full Stack Developer, SaaS Developer and MVP Developer with 15+ years of experience, 11,844+ Upwork hours and 181 completed jobs. I build SaaS products, MVPs, platforms, automation systems and custom web applications for startups and businesses.
If you need a Full Stack Developer who can understand the requirements, plan the build, write the code, ship the product and keep improving it after launch, that is the work I do every day.
WHAT CLIENTS HIRE ME FOR
Most clients come to me at one of two moments. They either have an idea and need an MVP Developer to turn it into a real product, or they already have a platform and need a Full Stack Developer to take it over, improve it and keep it moving. I'm equally comfortable starting from an empty repository or an existing codebase.
SaaS platforms and multi-user business applications
MVP builds for founders validating a first product
Dashboards, admin panels and customer portals
CRM systems, internal tools and workflow automation
Marketplaces, booking platforms and web applications
AI-powered products, LLM assistants and document interfaces
RESULTS I HAVE DELIVERED
Improved API response times by up to 40% through better queries and caching.
Reduced database query times by up to 45% through indexing and database optimization.
Improved application load performance by up to 35% through frontend optimization.
Reduced MVP delivery time by up to 25% through focused development.
Reduced manual operational work by up to 30% through automation and connected workflows.
Supported products reaching 2M+ users and workflows handling 100K+ automated actions.
HOW I WORK AS AN MVP DEVELOPER
I keep the first release focused: one core user journey, the business logic it depends on, and an architecture that can grow with the product.
I will tell you honestly which features can wait until after launch. As an MVP Developer, I would rather ship 5 features that work properly than 15 that only half work.
Several products I've started as an MVP Developer have grown into full SaaS platforms, with continued development after launch.
WHAT I BUILD AS A SAAS DEVELOPER
Sarbjeet S. earns an estimated $5.6k/mo. That's 4.7× the typical freelancer and more than 99.62% of everyone we track.
I build the parts most SaaS products need: authentication, role-based access, admin panels, customer portals, subscriptions, payment flows, reporting, notifications and business workflows.
As a SaaS Developer, I focus on production-ready systems rather than demos, with architecture that can evolve as users and business requirements grow.

Backend: Node.js, Python, FastAPI, PHP, Laravel, REST APIs

As a Full Stack Developer, I can work across frontend, backend, databases, APIs, integrations, deployment and environments.
INDUSTRIES

This experience helps me understand the real-world business rules, integrations, approval workflows and edge cases that come with production applications.
WORKING WITH ME
One Full Stack Developer owns the whole build, so nothing falls between multiple developers.
Short written updates and early communication when something needs attention.
Clean, documented code that another developer can understand and continue.
$200K+ earned, 181 completed jobs and 11,844+ Upwork hours.
Comfortable with both fixed-scope projects and long-term development.
