Top Rated
Project details
Custom LangChain AI agent with multi-tool integration (3-8+ APIs/tools). The agent reasons through problems, selects appropriate tools, and handles errors automatically (retries, fallbacks). Examples: research agent (searches + analyzes), sales agent (qualifies + quotes + logs), support agent (searches KB + escalates). Error handling is built-in. Memory management (short-term + long-term). Expected: 60-80% automation of manual tasks, improved accuracy, and source citations. Full source code ownership.
SERVICES
✓ Multi-Tool Integration (3-8+ APIs/databases/SaaS)

Build Custom KiSS Rewards Platform for Small Marketing Agency (AI-Driven, Retainer-Based)
Habib and his team exceeded my expectations in every way. We partnered with them to build a full SaaS platform for our KiSS Club rewards system, and the experience was exceptional from beginning to end. They were highly responsive, smart, and deeply knowledgeable across all technical aspects of the build.
What impressed me most was their attitude when we encountered challenges. Instead of getting defensive or stalled, they jumped in with creative ideas, strong problem-solving, and a genuine desire to help us find the best solution. Their communication was consistent, their professionalism was outstanding, and the quality of the finished platform is exactly what we hoped for.
They were an absolute pleasure to work with, and I recommend them without hesitation. I will definitely hire them again for future development needs.

Shipping features is easy. Designing the system behind them to handle multi-tenant complexity, AI workloads, security, and 10x growth is not.
That’s where I come in.
I’m an AWS Certified Solutions Architect with 9+ years of experience designing scalable SaaS and AI systems for startups and enterprises across the US, UK, KSA, and Australia.
