For the last three years I've been the founding engineer at DroneLeaf, a UAE drone-fleet platform, where I own the AWS architecture end to end: the serverless backend, real-time IoT, the on-device software and the release pipeline. What I can build or fix for you: • AWS serverless backends: Lambda, AppSync/GraphQL, DynamoDB, Cognito, API Gateway, Amplify, CloudFormation/CDK • Architecture reviews, cloud migrations, and reliability or cost fixes • IoT and real-time systems: AWS IoT Core fleet provisioning, MQTT, WebSockets, WebRTC • Node.js/TypeScript and Python APIs with multi-tenant auth, RBAC and Stripe billing • Angular/Ionic apps for web, mobile and desktop, plus native Android (Kotlin, Jetpack Compose) • CI/CD: GitHub Actions with OIDC, multi-arch Docker builds, Debian packaging for embedded Linux • AI features: LLM integration, RAG, MCP servers, multi-provider LLM routing Recent work: • Moved a live production platform from AWS Bahrain to Frankfurt with minimal downtime (S3 replication, ECR migration, DynamoDB Global Tables). That replication setup is now its disaster-recovery base. • Designed a role-based authorization platform used by 8 Lambdas and the client app, dark-launched behind CI gates and Playwright tests. • Fixed an MQTT subscription bug that took subscribe failures on an 83-device tenant from 1,828 to 0. • Built My Stream alone: an AI publishing platform running on 7 LLM providers, with Stripe billing. • Published Online Quran, an Android app that has been live on Google Play for years. I also keep public, tested code on GitHub: a graph database written from scratch, an MCP server for safe LLM database access, and an LLM routing library. I work async across time zones (GMT+3), write clearly in English and Arabic, and document what I ship so your team can run it after me. Send me what you're working on. less -

I'm a full-stack developer running MapleStack, helping businesses turn ideas into working software across web, mobile, and AI-integrated platforms.

Experience 8+ years...I'm a full-stack developer running MapleStack, helping businesses turn ideas into working software across web, mobile, and AI-integrated platforms. My approach is simple: understand the real problem first, scope honestly, then build something clean enough to still make sense a year from now. Experience 8+ years across SaaS platforms, e-commerce systems, and AI-integrated web applications. I've built custom CRMs, marketplace platforms, booking and payment systems, and automation pipelines connecting LLMs to real business workflows. Core Stack Frontend: React, Next.js, Vue.js Backend: Node.js, Laravel, Express, Django/Flask where the project calls for it E-commerce/CMS: WordPress, WooCommerce, Shopify, PrestaShop Databases: MySQL, PostgreSQL, MongoDB, Supabase AI/Automation: OpenAI and Anthropic API integration, n8n, LangChain-based agent workflows Payments/Integrations: Stripe, PayPal, Twilio, REST/GraphQL APIs, headless CMS Background Bachelor of Commerce (Marketing) and a BSc in Psychology, which shapes how I think about the projects I build, not just the code, but the user behavior and business logic behind it. Certified in Google Ads Search, Google Analytics, and Microsoft 365 SMB Sales. How I Work Every project starts with real scoping, not a generic quote. If something sits outside my direct experience, I say so upfront and propose a way to bridge it responsibly, whether that's a smaller first milestone to prove capability or an honest caveat before we commit. I'd rather lose a bid on transparency than win one on an inflated claim and disappoint a client six weeks in. What You Get Clean, maintainable code. Realistic timelines. Direct communication throughout, no disappearing between milestones. And a developer who treats "I don't know that platform yet, but here's how I'd approach learning it responsibly" as a legitimate answer, not something to hide. If it's technically achievable, I can build it, and I'll tell you plainly if it isn't. less -
