A couple of most notable projects that I managed, my responsibilities & key achievements:
1) Project manager for a SaaS web application that generates human motion animations using AI
- Led the development of the 3-year project to the successful release on time & budget
- Established the planning process for training ML models that allowed us to meet the expectations of the client for the scope and timing of the public beta release
- Reorganized our processes to switch to regular monthly releases to aid with user retention and increase MRR
- Interviewed and brought consultants to the team to complement our skillset in specific domains like 3D animation, SEO, Auth0

You have an idea for an AI-powered product. You need it built fast, but you also need it to actually work in production - not just a demo that crumbles under real users. Most developers on UpWork platform have never touched a production LLM system.
I am a top 1% Expert-Vetted on Upwork. I've built AI systems that drove ~$67M in revenue at eBay, led product at Remitly and PwC, and shipped 15+ AI apps used by 1M+ people. If you need an AI product that actually works in production - not a prototype - I'm the person who delivers it.
𝐇𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤:
Every project comes with a 𝐦𝐨𝐧𝐞𝐲-𝐛𝐚𝐜𝐤 𝐠𝐮𝐚𝐫𝐚𝐧𝐭𝐞𝐞. You either love the work or you get paid to find out.
I ship using AI-native workflows at 3-5x traditional dev speed. And unlike most AI devs, I've spent years as a product leader - so you get someone who thinks about users and revenue, not just architecture.
Send me a message with your idea and I'll send you a 5-minute Loom video - an honest take on feasibility, timeline, and what you actually need. No pitch, no obligation.
Results I've delivered:
- $67M GMV uplift - AI model at eBay
- $10M+ revenue acceleration at Remitly - growth loops powered by AI-driven attribution and personalization
- $20K/month marketplace - fractional CPO, AI-powered matching and analytics
- BlinkDo - AI-native book summaries, 1,000+ downloads, live on iOS and Android
- An AI dating coach app with RAG pipelines (launched March 2026)

I build systems that let founders step away from the daily operations of their business.
Most founders hire a team expecting things to get easier.
Instead, they become the bottleneck. Every decision, every follow-up, every "where are we on this?" still runs through them. I fix that.
I come in, understand how your business actually works, and build the operational infrastructure around it - custom dashboards, workflows, delivery tracking, SOPs, and automations designed for how your company runs.
My process: define your deliverables → break them into workflows → map every task → assign ownership and timelines → systemize everything so work moves without you pushing it.
Over the past 7+ years I've:
📌 Built delivery systems supporting $250K+/month in recurring revenue
📌 Cut project turnaround from 15 days to 3 by redesigning operations
📌 Turned teams that needed daily check-ins into ones that run full delivery cycles on their own
📌 Structured and managed remote teams of 10–30 people across 5+ time zones
📌 Took founders from 60-hour weeks buried in operations to fully stepping back within 30 days
What I deliver:
→ Operations Audit - I map how your business actually runs, find the bottlenecks, and show you exactly what's broken and where to start
→ Custom Dashboards - Built around your business, not a template. Client tracking, task boards, pipeline visibility, finances, all in one place
→ Workflow Design - Every deliverable broken into clear steps, owners, and timelines
→ SOPs & Process Documentation - Everything your team needs to execute without asking you, written step by step
→ Automations - I eliminate the repetitive manual work so your team focuses on what matters
→ Project Management Systems - Structured the right way so your team actually uses it
→ Team Structure & Accountability - Clear roles, ownership, delivery cadences, and escalation paths so you're not the one following up
→ Reporting & KPI Tracking - Systems that show you what's happening without you having to ask
→ Onboarding Systems - For clients and team members, documented, repeatable, and fast
→ Fractional COO Support - Ongoing operational leadership so your business keeps running tight as you scale
Clients say:
⭐ “Thiane is not only a pleasure to be around, she is a natural superstar. In my opinion, she is one of the most gifted and talented individuals I've seen in a long time, and we are fortunate to have met her and to work with her.” - Robert Nizielski, CEO at 2x2 Partners
⭐ "Thiane was a total game changer. I had a bunch of things scattered across docs, emails, and my brain, and within a few weeks she built a full Asana setup from scratch that actually made sense for how we work. Now everything is organized, automated, and moving without me needing to check in all the time." - Amy Lynn, CEO at Amy Lynn Interior Design
⭐ "Thiane came in and completely transformed how we work. She took our studio-based setup and turned it into fully digital operation. She built our entire system in Asana from scratch, trained the team, created SOPs, and got everyone aligned fast. One of the most reliable and sharp professionals I have worked with." - Daniel Probert, CEO at Wowmi
I'm the right fit if you're a founder who:
→ Hired a team but still runs everything
→ Has no visibility into what's getting done
→ Spends more time managing than growing
→ Needs real systems, not another tool setup

I design and ship production AI systems — voice agents, multi-agent platforms, and AI automation that actually work at scale, not demos that break in week two. Companies hire me in one of three roles:
🔹 AI Consultant / Architect — I audit your AI product or design one from scratch: architecture, model selection (OpenAI, Claude, open-source LLMs), RAG pipelines, agent orchestration, cost optimization, and a realistic roadmap.
🔹 Voice AI Engineer — I build production voice agents: AI receptionists, outbound sales agents, call center automation. Full telephony stack (Twilio, LiveKit, SIP), real-time latency under 200ms, interruption handling, multilingual. I can also deploy fully on-premise/on-device when data privacy matters (healthcare, legal, government).
🔹 Fractional CTO/CPO — I take your idea to an investable, shippable product: discovery, MVP scoping, hiring engineers, leading delivery, preparing the tech story for investors.
18+ years building deep-tech products. I've architected AI brains for humanoid robots, shipped voice platforms handling real customer calls, and built complete AI stacks (ASR, TTS, LLM inference, memory, orchestration) — not just OpenAI API wrappers. When your project needs edge deployment, offline AI, or infrastructure that survives production load, that's exactly where I work.
Recent results:
• Voice AI call center infrastructure — automated inbound/outbound sales calls, multilingual, with analytics and routing
• Digital clone platform (Callable) — AI replicas of experts with preserved voice, knowledge, and personality
• Cognitive runtime for robots and kiosks (IronHeart.AI) — real-time conversation with memory on edge devices
• Enterprise data intelligence platform — AI agents over structured/unstructured data with MCP integrations and RAG
I work solo for strategy and architecture, and bring my engineering team when the scope requires full delivery.
Let's talk if you need an AI system that has to work in production — message me with a short description of what you're building.
