Senior full-stack engineer and team lead with 20+ years of experience. I specialize in real-time video / WebRTC streaming and in AI/ML systems that ship to production.
I currently lead engineering at a live-video startup, where I architect streaming, scalable real-time chat, and AI features across the entire stack. Across my career I've built high-load platforms, custom HTML5 video players, and developer tooling serving thousands of concurrent users.
I can help you with two things in particular:
Real-time video & streaming: WebRTC, live streaming, HLS, HTML5 and custom video players, low-latency media pipelines, and scalable chat.
AI/ML engineering: LLM-powered apps, MCP servers & plugins, autonomous agents and workflows, RAG with vector databases, model fine-tuning (Hugging Face, PyTorch, LoRA/PEFT), and reinforcement learning (training models and building custom RL environments).
Core stack: TypeScript/JavaScript, Go, Python, Rust, Node.js, React, Next.js; PostgreSQL, MongoDB, Redis; Google Cloud, AWS, Docker, Kubernetes.
Open-source author: I created and maintain StateFlow (stateflow.dev) โ a type-safe, predictable state-management library for TypeScript, running in production at the company I lead.
What you get working with me: clean, testable, production-grade code; clear communication; and a senior engineer who can both lead the architecture and do the hands-on work to ship it.
Building a video product, an AI/LLM feature, or an autonomous agent or need a senior lead to take something from idea to launch? Send me a message with a few details about your project and I'll tell you exactly how I'd approach it.

Most AI consultants build demos. I build systems that run in production.
I spent 20 years shipping software before going deep on Generative AI. Now I architect and deliver RAG systems, multi-agent applications, and LLM-powered products for clients who need more than a proof of concept. I work with GPT-4, Claude, Gemini, and open-source models like Llama and Mistral. I use LangChain and LangGraph to orchestrate agents that actually coordinate work across tools, APIs, and teams.
What sets me apart: I deploy AI on-premise. When your data cannot leave your building, I run models locally on Apple Silicon (MLX) and NVIDIA GPUs (CUDA). I have built HIPAA-compliant training pipelines where PHI never touches the cloud. I benchmark and optimize models on your hardware, not mine.
I run Stratus Labs, a private AI R&D firm focused on forward-deployed AI engineering. I embed with clients, map their systems, build the missing pieces, train their teams, and hand off ownership. I lead a senior engineering team, communicate directly with US clients in US hours, and deliver on schedule.
๐๐ก๐๐ญ ๐ ๐๐๐ฅ๐ข๐ฏ๐๐ซ
Production RAG systems over private document sets for legal, healthcare, financial, and operational use cases. Hybrid retrieval, reranking, citation extraction, reduced hallucination.
Multi-agent workflows that coordinate tasks across email, calendar, CRM, and internal tools using LangGraph orchestration with human-in-the-loop approval gates.
LLM MVPs and POCs delivered fast. Spec to working demo in days, not months. Production-ready architecture from day one.
Full-stack AI applications with React, Next.js, Python/FastAPI, and Node.js. APIs, integrations, and real-time AI UX.
On-premise LLM deployment and fine-tuning on Apple Silicon (M1/M2/M3/M4 Ultra, Mac Studio, Mac Pro) and NVIDIA GPUs (A100, H100, RTX). Air-gapped environments with zero cloud dependency.
๐๐๐๐๐ง๐ญ ๐๐๐ฅ๐ข๐ฏ๐๐ซ๐ฒ
Real estate operations: AI document intake replaced 6+ hours of manual review with 15-minute automated triage. Multi-agent email coordination now handles 80% of vendor communications.
Legal services: RAG assistant over 50K+ documents cut attorney research time by 70%.
Healthcare (HIPAA): On-premise LLM training on Apple Silicon. PHI stays local. Full compliance, zero cloud.
Private equity: Automated due diligence extraction reduced analyst review from 2 weeks to 2 days.
SaaS company: AI support triage with 60% ticket deflection and 3x faster resolution.
Marketing agency: On-brand content generation trained on client voice data. 85% of first drafts pass review.

Hi, I'm Laiba๐ Send me an invite or message, and I'll reply with a personalized Loom showing exactly how I'd automate your workflow.
โ Saved $4,255+/mo for a leading e-commerce bookstore by automating inventory management

A longer, more detailed breakdown:
Pleasure to meet you! Most clients work with me because I quickly understand messy business workflows and turn them into high-ROI automation systems.
I currently serve as a lead engineer at Automation Architecture AI, a global agency focused on building operational automation systems for businesses. I also work directly with companies to eliminate CRM bottlenecks, streamline content pipelines, and build AI agents that completely handle operational work.
What I'm best at:
โ Advanced Workflow Automations
I design production-grade automations built to scale. Using Make and n8n, these systems connect CRMs, email, databases, payments, and internal platforms. I specialize in automating dashboards, client onboarding and billing, content pipelines, task orchestration and lead capture systems. Every tool can be integrated with custom APIs when needed.
โ AI Agents
I develop custom AI agents and intelligent chatbots powered by GPT-5, Claude Opus/Sonnet 4.6, Gemini 3, LLaMA, and others. These agents handle lead qualification, outbound outreach, document processing, and act as digital operators for your business 24/7.
โ CRM & Live Database Systems
I automate pipelines and live data syncing with HubSpot, Salesforce, GoHighLevel, Airtable, Notion, Supabase, and Pipedrive, creating dashboards that free your team from repetitive database work and let them focus on revenue.
โโโ
I leverage my experience building intelligent systems to deliver high-ROI automation solutions for your business. If you're looking for a partner who can architect reliable systems that scale, send me a message. I'd love to discuss how I can help you achieve ๐ฒ๐จ๐ฎ๐ซ ๐ ๐จ๐๐ฅ๐ฌ.

I build and fix WordPress & WooCommerce sites on fixed prices with committed delivery dates. Most projects ship in days, not weeks. $80K+ earned on Upwork across 49 jobs, including a 773-hour WooCommerce engagement for a single client: custom cart flows and a product build-out configurator for a lighting company.
By day I'm a senior developer at StudioRx (Omnicom Health), building React, Next.js, TypeScript and WordPress applications under strict regulatory and accessibility standards. I'm the internal subject matter expert for ADA/WCAG accessibility, I typically handle the most complex backend work, and the signed, cross-platform desktop app I built replaced a local-server workaround for convention panels and became the standard delivery format across the practice. By night I take one or two Upwork projects at a time, so your project gets focused, senior-level attention without agency overhead.
What I bring to your project:
โข WordPress & WooCommerce: custom themes and plugins, payment gateways (Stripe, PayPal, and friends), catalogue/enquiry builds, LMS and membership sites, migrations with SEO intact. When an off-the-shelf plugin can't do it, I read the WooCommerce core and make it do it.
โข Full-Stack: PHP/MySQL, Node.js, REST/GraphQL APIs, React, Vue, Next.js, Tailwind CSS.
โข Performance and accessibility: deep audits of bloated plugins, custom replacements, cache and asset strategies, Core Web Vitals in the green, WCAG that passes an audit.
โข Technical leadership: development standards, QA checklists and AI-assisted workflows that a team can run without me.
โข Automation-heavy delivery pipeline (scaffolding, testing, content population). It's how I quote days instead of weeks.
How I work: fixed price, milestone by milestone, with a delivery date in writing. You review and approve each milestone before releasing payment. Staging first; your live site is never the test environment.
If you need clean, maintainable code delivered on a date I put in writing, let's talk.
