When we had initiated our cap project, although specific instructions were clearly specified, however, many of the freelancers hadn’t a clue on how to design this product.

Once we got a reply from Haradhan, we knew immediately he was our man for this project.

Haradhan is a superb freelancer, a good listener, aside from being very talented in his field. Pays attention to detailed instructions and implement them.

Wed are very pleased with this freelancer , as we will use him for other incoming projects.

Profile Overview
Are you looking to build high-performance web systems, scale your engineering infrastructure, or deploy self-hosted AI without exposing proprietary data?
I am a Senior Software Architect and Full-Stack Developer with 15+ years of enterprise experience. I design and build everything from high-converting business websites, CMS systems, and e-commerce stores to high-concurrency backend engines, custom ERPs, and secure AI infrastructure.
Whether you need a reliable partner to launch a fast, business-ready website or an experienced lead developer to optimize complex web apps and backend databases, I deliver secure, production-ready, and fully scalable software tailored to your budget.

🛡️ SOVEREIGN AI & ENTERPRISE RAG ARCHITECTURE
Eliminate per-user SaaS fees and protect your intellectual property with self-hosted AI infrastructure.

Sovereign RAG Pipelines: High-accuracy Retrieval-Augmented Generation systems grounded in your private enterprise databases using PostgreSQL (pgvector), Pinecone, and LlamaIndex.
Private Agent Gateways: Turnkey deployments of OpenClaw, Hermes Agent, and AnythingLLM running behind secured reverse proxies (Nginx/Caddy) with local LLM orchestration (Llama 3, Gemma).
Autonomous Business Agents: 24/7 background AI workers integrated with n8n to automate CRM updates, market research, document processing, and reporting.
