Flutter Mobile application development
No project is without challenges, but the team remained committed to finding solutions and delivering results. They were responsive to feedback, open to revisions, and demonstrated strong perseverance throughout the development process.
We are pleased with the outcome and appreciate the effort invested in bringing NafaPay to life. We would be happy to work with them again on future projects.

Environmental Risk Forecast & Alert App (MVP)
The core functionality (risk alert logic) does not work correctly and does not match the agreed requirements. The freelancer acknowledged the issue but did not fix it. The delivered work is incomplete and not usable.

AI productivity apps don’t fail because of the UI.
They fail because memory breaks. Context disappears. AI outputs become inconsistent. Mobile latency kills retention.
Founders bring me in when their AI-native app works beautifully in a demo, but becomes unreliable in real-world usage.
Where AI Productivity Apps Break
If you're building:
• Voice-to-task AI apps
• AI workflow automation tools
• Mobile AI agents
• Enterprise AI productivity platforms
And facing:
• Context retention failures
• Weak vector retrieval accuracy
• LLM hallucination or inconsistent outputs
• Slow AI responses on mobile
• Sync conflicts across devices
• Governance & compliance concerns
That’s rarely just a model issue. It’s an architecture issue.
What I Actually Build
I combine 5+ years of enterprise Flutter architecture ($100k+ earned on Upwork) with production-grade AI engineering. I architect AI-native productivity systems using the right stack, not just random API glue.
📱 Frontend (Mobile & Cross-Platform)
• Flutter (Clean Architecture, SOLID, MVVM)
• Riverpod / Bloc for state management
• WebSockets / real-time sync
• Offline-first design
• Performance tuning for low-latency AI UX
🧠 LLM & AI API Orchestration
• OpenAI API (GPT-4o, embeddings), Anthropic Claude, Google Gemini
• Function calling & tool usage pipelines
• Structured output enforcement (JSON schema validation)
• Deterministic response layering & Guardrails to reduce hallucination
📚 RAG & Vector Systems
• Pinecone, Weaviate, Supabase Vector, PostgreSQL + pgvector
• Custom embedding pipelines
• Retrieval tuning (chunking strategy, re-ranking, hybrid search)
🗂 Persistent Memory Architecture
• Session memory + long-term memory layers
• Structured memory graphs & Event-based memory storage
• Context summarization pipelines
• Cross-device state synchronization
☁️ Backend & Infrastructure
• Firebase (Auth, Firestore, Functions) & Supabase
• Node.js / Python microservices
• REST & GraphQL APIs
• Multi-tenant architecture & RBAC for enterprise
The Goal: AI Reliability
When AI is inconsistent: Users churn. Workflows break. Enterprise deals stall.
When AI becomes stable, contextual, and fast: Retention increases. Daily active usage scales.
My focus is measurable retention uplift through stable memory systems, retrieval accuracy, deterministic LLM orchestration, and low-latency Flutter UX. This is AI reliability engineering, not surface-level integration.
Who I Work With
• Seed to Series B AI productivity startups
• B2B SaaS founders building AI-native workflows
• Enterprise-focused automation platforms
(Note: I do not take on generic, brochure-style mobile app builds. I partner with serious product teams solving retention and reliability at scale.)
Authority & Track Record
• $100,000+ earned on Upwork building scalable mobile systems
• Technical founder-level thinking
• Proven production AI systems shipped
