Ali H.

I help startups, growing businesses, and established companies build, scale, and maintain reliable software products. With 7+ years of experience, I bring hands-on engineering expertise, technical ownership, and product-focused problem-solving. Having worked with international companies and distributed teams, I understand that successful software development goes beyond writing code. I take ownership of projects, make informed technical decisions, identify potential issues early, and work closely with stakeholders to turn business requirements into scalable solutions. I can take a product from concept to production, lead technical implementation, or step into an existing codebase and manage ongoing development. AI, MCP & RAG DEVELOPMENT I build AI-powered applications and integrations that help businesses automate workflows, improve information retrieval, and make better use of their data. • AI chatbots, virtual assistants, and conversational interfaces • RAG systems for PDFs, documents, websites, and private knowledge bases • MCP servers and third-party tool integrations • AI agents and automated workflows • AI-powered search and document processing • OpenAI, Claude, Gemini, and Mistral integrations • Pinecone, Weaviate, pgvector, LangChain, and LlamaIndex SAAS & FULL-STACK DEVELOPMENT I develop SaaS platforms, business applications, dashboards, marketplaces, and customer-facing web applications, with an emphasis on maintainability, performance, and long-term growth. Technologies: React, Next.js, TypeScript, Node.js, Express.js, NestJS, PostgreSQL, MongoDB, Supabase, and Firebase. MOBILE APP DEVELOPMENT I build and maintain cross-platform iOS and Android applications using React Native, Expo, and React Native CLI. My experience includes GPS and maps, real-time functionality, push notifications, payments, subscriptions, authentication, API integrations, AI-powered features, and app performance optimization. BACKEND DEVELOPMENT & API INTEGRATIONS I design and implement backend services, REST APIs, database architectures, and third-party integrations for reliable and scalable applications. Technologies and services include Node.js, Express.js, NestJS, Python, PostgreSQL, MongoDB, Supabase, Firebase, Stripe, Twilio, Google APIs, mapping services, webhooks, and authentication providers. BLOCKCHAIN & WEB3 I also have experience with blockchain applications and Web3 integrations, including smart contracts, wallet connectivity, tokens, NFTs, and EVM-based applications. TECHNICAL OWNERSHIP & EXISTING PRODUCT DEVELOPMENT Already have a product in development? I can step in and take ownership. LET'S DISCUSS YOUR PROJECT If you're building a SaaS platform, web application, iOS or Android app, or AI-powered product involving MCP, RAG, or AI agents, I'd be happy to discuss your requirements and recommend a practical technical approach. I'm available to work with international teams across time zones, can start immediately, and am comfortable with both part-time and full-time engagements.
