Kalu Eke
About this gig
I engineer production-grade AI web applications and autonomous agentic workflows built for scale. This service combines modern full-stack development with advanced AI integration to deliver secure, reliable software architectures.
Every platform optimizes performance via custom backend integration, automated pipelines, and minimalist B2B visual frameworks.
What I Build:
- Full-Stack Web Applications: Responsive frontends, custom user authentication, dynamic UI components, and secure administrative control panels.
- Intelligent Agentic Workflows: Custom state-machine execution, automated data ingestion pipelines, and local model orchestration.
- Minimalist Interface Systems: Clean B2B layouts, precise isolated asset extraction, and visual hierarchies that eliminate redundant UI elements.
Target Platforms: B2B financial tools, administrative portals, custom SaaS, and automated service pipelines.
Core Tech Stack:
- Frontend: Next.js, React, TypeScript, Tailwind CSS
- Backend & DB: Node.js, Python, Supabase, PostgreSQL, REST APIs
- DevOps & AI: LangGraph, Docker containerization, Ollama
Please message me detailing your technical and business scope before placing an order.

FAQ
Can we run AI models locally to avoid API costs?
Yes. I deploy open-source LLMs using Ollama and Docker containers. This keeps your sensitive operational data on your own infrastructure and eliminates recurring third-party API fees.
How do you secure user roles and database access?
I configure Supabase and PostgreSQL with strict Row-Level Security policies. Paired with a Next.js frontend, this ensures users and admins only access their authorized data without breaking platform performance.
How do you prevent AI agents from hallucinating?
I build state-machine workflows using Python and LangGraph. This gives the agent structured memory and execution boundaries, ensuring it executes complex multi-step logic reliably instead of generating random outputs.
Is this built with custom code or no-code wrappers?
A: This is 100% custom-coded software using Next.js, Supabase, Python, and LangGraph/langchain. I engineer production-grade platforms rather than relying on fragile no-code tools.
What if I do not have detailed technical specifications yet?
The Basic tier ($180 Discovery & Architecture) is built specifically for this. We map out your system architecture, data flows, and technical scope before writing a single line of code.
Can we host AI models locally for strict data privacy?
Yes. I can deploy local open-source LLMs using Ollama and Docker containerization. This ensures your sensitive operational data never leaves your infrastructure.
Do you offer post-launch support and maintenance?
Yes. Standard and Premium tiers include post-delivery support to ensure smooth environment deployment, bug resolution, and operational handover.
How do you handle confidentiality and NDAs?
Your business logic, data, and codebase remain strictly confidential. I am happy to sign an NDA before reviewing proprietary specs or credentials.
Can your agent workflows handle complex multi-step tasks?
Yes. I build state-machine workflows in Python using LangGraph. This allows agents to execute complex, multi-step logic, manage edge-case fallback states, and process data reliably.
What do you need from me to begin?
A clear summary of your project goals, any design references you have, and your technical requirements. Please send a message first so we can verify scope.
