About Stanly

Senior Full-Stack Developer & AI Engineer with 7+ years of experience building scalable web, mobile, and AI-powered applications on the MERN stack. I architect high-performance systems using GraphQL, REST APIs, and microservices.

What I've built:

Kawlo : A mobile platform with 1M+ downloads across iOS and Android, handling high-scale backend logic and real-time features.

GCERevision : An educational portal serving 80,000+ monthly users, built with custom Redis caching, raw SQL optimizations, and strictly typed OOP architecture.

Briant : A Generative UI engine that streams structured JSON to React, powering text-to-software workflows with agentic loops.

AgentB : An open-source AI developer framework for tool orchestration, human-AI interaction, and autonomous agent workflows.

WhatADress : A computer vision app using generative AI for media processing and image analysis.

Glamping Planner : A stateful LangGraph conversational agent with RAG pipelines and structured output.

Angela : A live AI Voice Agent built with custom Python/JS nodes inside n8n automation workflows.

Simplitill : A fintech POS application with Stripe integration and offline-first architecture.

I work daily with AI-native tools (Cursor, Copilot, Claude) and build automation pipelines using n8n, LangChain, and FastAPI. I'm passionate about turning complex problems into clean, reliable software at scale.
