Project details
Aivana is an AI mobile app that combines intelligent discovery of wallpapers with interactive virtual chat. Aivana includes an extensive catalogue of AI-generated wallpapers, from popular categories including motivational quotes, abstract forms, spiritual devotion, cosmic art, romantic visuals, nature shots, and modern portraits of all types. Aivana is lightweight and available anywhere and does not use subscription services. Aivana employs a unique “Luck Spin” scheme, where users can earn tokens to either qualify for downloads or continue their chat with the AI, without spending any “real” money. All wallpapers are royalty-free, frequently updated, and all allow for personalised using wallpapers to create real, fresh and unique visuals for users. Aivana utilizes Artificial Intelligence for creative generation (wallpaper), AI chat, uses Machine Learning models for personalisation and recommendations, uses Cloud Storage to host and deliver content instantaneously, and uses mobile UI frameworks for Android (Kotlin/Java) and iOS (Swift/Flutter). By combining creative visuals with AI chat interaction, Ativana offers an engaging, aesthetic, and cost-free mobile project experience.

He never worked during our scheduled hours. When we interviewed him, he agreed to work our hours, but then he changed his mind and wanted to work his own schedule. Based on this, I would not hire him.

Full overview
If you're building an AI agent, LLM-powered app, or intelligent SaaS product — I've likely already shipped something similar.
12,500+ hours on Upwork. 100% Job Success Score. 63 contracts completed. I don't experiment on your project. I bring production-proven patterns for AI systems and scalable cloud architecture.
— What I build for clients —
AI Agents & LLM Applications
RAG pipelines, multi-agent systems, chatbots, and AI workflows using LangChain, LlamaIndex, OpenAI (GPT-4o), Anthropic (Claude), Gemini, and AWS Bedrock. I've spent 3,200+ hours on a single long-term LLM project — I understand what it takes to ship AI that actually works in production, not just in demos.
Full-Stack Web Applications
React.js / Next.js frontends paired with Node.js (NestJS, ExpressJS) or Python (FastAPI, Django) backends. From architecture design to deployment on AWS ECS, Lambda, and EC2.
Cloud Architecture on AWS
Bedrock, Cognito, Appsync, Lambda, API Gateway, S3, ECS, RDS, CloudWatch, SES/SNS, Route53. I design systems that scale and don't break at 3am.

Backend: Node.js (NestJS, ExpressJS, Fastify), Python (FastAPI, Django), TypeScript
AI/ML: LangChain, OpenAI, Anthropic Claude, Gemini, AWS Bedrock, Grok

— Why clients keep coming back —
I treat your project like a product, not a task list. I flag risks early, communicate proactively, and write code I'd be comfortable maintaining myself. My 0-4 hour average response time means you're never waiting on a blocker.
