Require Java Spring boot Developer for critical issue Gulshair has a good grasp of Java Springboot and microservices. I highly recommend him. Not only he helped me in understanding the code but also took some effort in explaining the concept. For future I am definitely coming back to Gulshair. He managed to help at some odd hours, whenever I asked he made himself available from his busy schedule. Thank you, Gulshair. Keep up the good work

Lahore, Pakistan - 4:35 pm local time
Need a senior full stack developer who can take your product from architecture and backend APIs to a polished frontend and production deployment?

I build scalable Java/Spring Boot and React/Next.js applications, including enterprise platforms, multi tenant SaaS products, AI-powered systems, REST APIs, and microservices.

With 8+ years of software engineering experience, I help startups and established businesses build new products, modernize legacy applications, improve performance, integrate AI capabilities, and prepare systems for reliable production deployment.

My core services include:

• Full-stack SaaS and enterprise application development
• Java and Spring Boot backend development
• React, Next.js, TypeScript, and modern frontend development
• REST APIs, microservices, and third-party integrations
• Multi-tenant and modular application architecture
• Spring Security, OAuth2, Keycloak, and role-based access control
• PostgreSQL, MySQL, MongoDB, Redis, JPA, and Hibernate
• Database optimization, caching, and performance improvement
• Docker, CI/CD pipelines, Linux environments, and production deployment
• Legacy application modernization and technical-debt reduction
• Architecture reviews, code reviews, and technical consultation

I also design and integrate production-ready AI capabilities, including:

• Retrieval-Augmented Generation (RAG) systems
• AI agents, copilots, assistants, and automated workflows
• LLM and generative AI API integrations
• Document ingestion, knowledge bases, and semantic search
• Vector database integration and retrieval pipelines
• AI agents that interact with APIs, databases, and business tools
• Internal knowledge assistants trained on company documents
• Customer-support and domain-specific AI assistants
• Source-grounded question-answering systems
• AI-powered dashboards and productivity features

My work goes beyond simply connecting an application to an AI API. I focus on the complete production architecture including data ingestion, retrieval quality, authentication, access control, observability, evaluation, scalability, cost management, and protection against unreliable AI responses.

I can join an existing development team, independently deliver a module, modernize an older system, integrate AI into an existing product, or develop a complete full stack SaaS platform from the ground up.

Tell me about your product, business workflow, technical challenges, and expected outcome. I will help you identify the right architecture and deliver a practical, secure, and scalable solution.
