Chandigarh, India - 1:12 pm local time

Most AI SaaS products work well in demos but struggle under real-world usage. I build production-grade systems that scale reliably, handle edge cases, and meet the security and compliance requirements of regulated industries.

My experience spans AI-powered SaaS platforms, agentic workflows, Retrieval-Augmented Generation (RAG), healthcare integrations, and fintech infrastructure. I've helped startups and growing companies turn ideas into stable products that users can depend on.

What I Specialize In :
- SaaS Application Development
- MVP Development for Startups
- Full-stack development from architecture to deployment
- AI Agents, RAG systems, and LLM-powered applications
- SaaS MVP development and scaling
- Multi-tenant platforms with strong data isolation
- Healthcare integrations (HL7, FHIR, HIPAA-aware systems)
- Fintech platforms and compliance-focused infrastructure
- Technical leadership and fractional CTO support
- AI Integrations (OpenAI, LLMs, AI automation)
- Laravel & Node.js Backend Architecture
- React.js / Next.js Frontend Development
- API Development & Third-Party Integrations
- Workflow Automation (n8n, Zapier, Custom Automation)
- Stripe & Subscription Systems
- Cloud Deployment (AWS, DigitalOcean, Vercel)
- Performance Optimization & Scalability

Beyond Development :
I don't just build what's requested, I help identify the most effective technical solution before development begins. With 5+ years of experience leading architecture decisions and supporting founders as a technical partner, I focus on balancing speed, scalability, and business goals.

Proven Results :
Healthcare Infrastructure :
→ Built an HL7 gateway for HealthMosaic, endorsed by the VP of Enterprise Solutions at Fukuda Denshi USA.
→ Processes 10,000+ clinical messages daily from 200+ hospital monitoring devices.
→ Achieved 99% message delivery reliability.
→ Contributed to an estimated $400K annual operational savings.

Fintech Platform Development :
→ Developed a SEC Regulation CF-compliant backend for a U.S. fintech startup.
→ Delivered 248 automated tests with zero production defects at launch.
→ Designed secure, auditable infrastructure to support compliance requirements.

Technologies :
→ Frontend: React, Next.js, TypeScript, Tailwind CSS
→ Backend: Node.js, Python, NestJS, FastAPI, Express
→ AI/LLMs: OpenAI, Claude, LangChain, LangGraph, RAG, Vector Databases, AI Agents
→ Databases: PostgreSQL, MongoDB, Redis
→ Cloud & DevOps: AWS, Docker, Kubernetes, CI/CD
→ Healthcare & Compliance: HL7, FHIR, HIPAA-aware architectures, Audit Logging

What Makes Me Different:
- 265+ successful projects delivered
- $300K+ earned on Upwork
- 20,000+ working hours (long-term client trust)
- Clean, scalable, production-ready code
- Clear communication & fast response

Industries I’ve Worked With :
• SaaS Platforms
• FinTech
• EdTech
• HealthTech
• Marketplaces
• CRM & Internal Systems
• AI-powered Applications

What clients say:
"Best dev to work with on Upwork!!!"
"I had a very good experience with Taj and his team. We worked on an early phase MVP that we were able to bring to life and I look forward to working with them again in the future."
"Tajinder was great to work with. He is easy to communicate with and explains everything in clear, simple steps, which made the whole process smooth. He is transparent, honest, and puts in genuine hard effort.

If you're building in AI, healthcare, fintech, or any SaaS where it has to work the first time, send me what you're building. You'll hear back within a day on whether I'm the right fit, and I'll tell you straight if I'm not.

Let’s talk.
