Tools & Workflow

AI Agent Orchestration Platform
Forked and extended an open-source AI company orchestration platform into a custom deployment with multi-agent hierarchies, role-based heartbeat systems, and MCP tool integration. Integrated the BMAD methodology with 45+ workflow skills spanning the entire SDLC — from market research and PRD creation through architecture design, story development, and QA. Built a tiered skill variant system that reduces token consumption by 50-87% across agent fleets, and developed custom plugins for MCP bridging, authentication, and workspace initialization. Agents operate autonomously with heartbeat-driven execution, git-tracked workspaces per issue, and budget enforcement.

AI-Powered Trading System
End-to-end automated trading platform with market data ingestion, AI-driven strategy generation from case studies (including chart image analysis via LLM vision), backtesting engine with 7 ranking metrics (Sharpe, Sortino, Calmar, profit factor, win rate), and live execution. Multi-agent analysis layer using CrewAI. Built with Python, FastAPI, TimescaleDB, and Redis.

AI Memory & Knowledge Graph
Persistent memory system for AI agents using a "memory palace" metaphor. Semantic vector search via ChromaDB, temporal knowledge graph with validity windows, and 19 MCP tools for agent integration. 15K+ memories across 18 domains. Research into MemGPT hierarchical context management, Mem0 token-cost optimization (90% reduction), and embedding strategies (quantization, Matryoshka Representation Learning).

Android Camera App (in development)
RAW photography app that bypasses computational photography for natural, film-like images — filling a gap where no equivalent exists on Android. Camera2 API, real-time GPU shader preview (OpenGL ES 3.0), film simulation presets, and lens effects (prism, bloom, grain, halation). Kotlin, Jetpack Compose, Clean Architecture + MVI. Full product planning complete via BMAD methodology (83 functional requirements, 11 epics, 43 stories).

Verification Intelligence Platform
Distributed system for automated code quality analysis — test coverage evidence collection, skill-based analysis execution, and CI integration. 5-container architecture with BullMQ job orchestration and SSE real-time progress updates.

Business Automation Systems
AI-driven automation for service businesses — messaging platform integration (WhatsApp, Telegram, Instagram), appointment scheduling, lead management, and workflow orchestration using LLM-driven agents and n8n.

Biometric Identity & Payments Platform
Cross-platform biometric identity verification system using palm vein authentication, built in close partnership with Fujitsu — co-developing SDK features, debugging, and reviewing documentation. Products spanned kiosk self-service enrollment, bank-grade transaction verification, and high-security payment authentication. Flutter with clean architecture, native platform channels for biometric hardware, Arabic/English i18n, and Azure CI/CD pipelines. Deployed across hospitality, banking, and enterprise security in the UAE.

Live Aldar — Real Estate Property Management — Monstarlab
Solution architecture and delivery for Live Aldar, a property management platform for real estate owners in the UAE. Integrated UAE Pass for secure national digital identity authentication. iOS and Android.

Teyaseer — Government Housing Platform — Monstarlab
Solution architecture for Teyaseer, an Abu Dhabi government platform that guides UAE nationals through the entire journey of building their dream homes — from design and instant price quotation with full cost breakdowns for construction and bills in seconds, to contractor selection, construction oversight, and final key handover. Led the team from concept through delivery. Collaborated closely with the UAE Pass team to improve their React Native SDK, enabling seamless national digital identity integration across cross-platform mobile apps.

Banking Internal Systems — First Abu Dhabi Bank (FAB) — Monstarlab
Supported the engineering team in improving internal systems for FAB, the largest bank in the UAE and one of the largest financial institutions in the Middle East.
