Hey there! I'm Andrew, a Senior Software Engineer with 𝟏𝟐+ 𝐲𝐞𝐚𝐫𝐬 of experience shipping production apps at 𝐀𝐩𝐩𝐥𝐞, 𝐆𝐨𝐨𝐠𝐥𝐞, 𝐇𝐄𝐁, and 𝐔𝐒𝐀𝐀. Currently at Apple building agentic AI infrastructure. I bring big-tech quality to every project, whether you're a startup racing to launch or an enterprise that needs senior-level help.
WHAT I DELIVER
• Full-stack web and mobile applications from idea to deployment
• Agentic AI systems, RAG pipelines, and intelligent automation
• Conversational Voice AI pipelines, including real-time text-to-speech and custom voice cloning
• Cloud infrastructure that scales without breaking the bank
• Internal tools, admin systems, and APIs built for performance and reliability
TRACK RECORD
• Apple (current): Lead CLI engineer on Apple's Agentic Platform Team. Building the control plane for deploying and managing AI agents and MCP servers at scale using LangGraph, Ray, and Kubernetes
• Voice AI Architecture: Built and deployed end-to-end audio pipelines integrating cloud APIs (ElevenLabs) and self-hosted open-source models for ultra-low-latency, high-fidelity voice synthesis
• Apple (previous): Shipped a Vue.js admin system with OAuth 2.0, a Go/gRPC cloud backend, and an iOS app for internal marketing ops
• Google: Refactored an open-source tool used across hundreds of offices, saving billions in lost productivity
• USAA: Led the Savings Booster product that moved $160M+/year into member accounts. 2 years, zero major bugs
• HEB: Architected a NestJS microservices platform on GCP and led a 5-dev team to deliver a supply chain negotiation tool
CORE STRENGTH
• I think like a product owner, not just a coder. Smart architecture decisions early so you don't pay for them later
• Led teams of 5-10 devs and shipped on deadline at companies where failure isn't an option
• Clear communicator. I flag problems early, keep you in the loop, and treat your project like my own
TECH STACK
• ai/agentic: LangGraph, Ray, Claude Code, MCP, RAG pipelines, TensorFlow, ElevenLabs, Audio AI / TTS, Datadog, Grafana
• frontend: React, Angular, Vue, TypeScript, Swift (iOS)
• backend: Node.js, Go, Java, Python, NestJS, GraphQL, gRPC
• cloud/devops: AWS, GCP, Azure, EKS, Kubernetes, Docker, CI/CD, Ansible
• data: PostgreSQL, MongoDB, Kafka, Firebase
If you've got a project that needs senior-level engineering and someone who actually cares about the outcome, send me a message. I'd love to hear what you're building.

I engineer production-grade web applications and high-performance e-commerce platforms using a hybrid modular strategy. I construct the core system using my library of battle-tested modules, then leverage specialized E-commerce frameworks or Low-Code tools to further optimize complexity, cost, and risks. This approach decreases development budget and timeline by 30-60%.
Beyond building features, I am a performance guru. I optimize e-commerce stores for maximum speed (90+ Google PageSpeed), Technical SEO, and conversion – ensuring your platform doesn't just work, but ranks and sells.
🔹 Full-Stack: React, Node.js, Python (Django/FastAPI).
🔹 E-commerce: Advanced Shopify & WooCommerce (Headless, Custom Themes, Speed Optimization).
🔹 Performance Expert: Core Web Vitals, Technical SEO, Load Time Reduction, Caching strategies.
Core Technology Stacks:
MERN Stack (React & Node.js)
– Frontend: React 18, Next.js 14, TypeScript, Tailwind CSS, Material-UI.
– React Architecture: Hooks, Context API, Server Components, Suspense.
– Backend: Node.js/Express REST APIs, GraphQL, Microservices architecture.
– Real-time: Socket-io / WebSockets for chat.
– State Management: Redux, NgRx, Zustand, MobX, Signals.
– Build Tools: Webpack, Vite, Nrwl Nx.
E-commerce & Performance Engineering
– Shopify: Custom Theme/App development (Liquid, Remix), Headless builds.
– WordPress / WooCommerce: High-performance themes, Complex migrations, Headless setups.
– Optimization: Core Web Vitals (CWV), Technical SEO audits, Image compression pipelines.
– Infrastructure: Redis/Varnish caching, Cloudflare CDN configuration, Database query tuning.
Python Stack
– Web: Django & Flask for robust web apps; FastAPI for high-performance APIs.
– Data: PostgreSQL with SQLAlchemy; Pandas/Numpy for data processing.
– Async: Celery with Redis for background tasks.
Low-Code & No-Code Toolset
– Retool: Rapid development of Admin Panels, Dashboards, and Internal Tools.
– FlutterFlow / Bubble: Fast MVP builds and mobile-first prototypes.
– Automation: n8n, Make, Zapier for connecting apps without custom backend code.
My proprietary library of battle-tested components:
