Project details
You will get a high-quality full-stack web application designed to perform, scale, and deliver real business value. As a Senior Full Stack Developer, I specialize in React, Angular, and Node.js to build secure, responsive, and user-focused solutions.
Whether you need a SaaS MVP, business dashboard, AI-powered tool, or enterprise platform, I deliver systems built with clean architecture, optimized performance, and reliable backend infrastructure. I handle frontend, backend, APIs, authentication, databases, and deployment from end to end.
You will receive a modern, professional product that works across devices and browsers, integrates with third-party services, and is easy to maintain. My process includes clear communication, transparent delivery milestones, and documented source code so you can continue development confidently.
I care deeply about delivering solutions that scale not just code that works. My goal is to help your business launch faster, operate smoother, and grow with confidence.

Developer Needed for Ongoing Project Support
Temurjon came into the project mid-way. He was able to onboard fast and keep the project moving when without him it would have delayed. He brought good solutions to the unique challenges and spent time understanding the project. His availability to work on the project was greatly appreciated. I would hire Temurjon again for any of my software solutions projects.

Job Success
Sachse, United States - 1:24 am local time
I help SaaS, healthcare, fintech, and automation teams build production-ready AI and full-stack systems.
Best fit: AI integrations, RAG systems, internal agents, document processing, backend automation, scalable SaaS architecture, and technical rescue work.
I work well with clients who need reliable backend design, clean data flow, secure APIs, cloud deployment, and long-term maintainability.
Core areas:
- AI, LLM, RAG, agents, chatbot workflows, document processing, and semantic search
- React, Next.js, Angular, TypeScript
- Node.js, NestJS, Python, FastAPI, Django
- PostgreSQL, MongoDB, Redis, Prisma, Elasticsearch/OpenSearch
- AWS, Docker, Kubernetes, Terraform, CI/CD
- Healthcare SaaS platforms involving EMR/EHR, patient portals, billing workflows, and clinical documentation systems
- FinTech, bill pay, banking, payment workflows, and multi-tenant SaaS platforms
- SaaS refactoring, backend performance, architecture cleanup, and technical rescue work
Relevant experience includes:
- Healthcare platforms involving EMR/EHR, patient portals, billing, inventory, and clinical workflow automation
- AI-powered clinical documentation and voice-to-text workflows
- AI dental application using Next.js, NestJS, FastAPI, PostgreSQL, and LLM integrations
- AI-powered property management SaaS with workflow automation and document processing
- FinTech and bill pay architecture for multi-tenant platforms
- AWS Lambda and ETL pipeline optimization
- Redis Oplog and Meteor performance optimization
- Document processing AI agents and RAG-based workflows
I think like an architect, but I still write code. I care about clean architecture, security, testing, failure handling, and simple communication.
I do not build fragile demos. I build systems that can survive real users and be maintained after launch.
If your project needs a senior engineer who can understand the product, identify technical risk, and ship reliable software, I can help.
