Case 01/Fintech & Crypto/Proof Engine project
Revenue-based capital platform for creators
Testing whether creators and capital providers would engage with a revenue-backed financing product.
What we did
Mapped segments, tested four offer framings, built an application-style MVP, and ran creator and capital-side conversations.
Outcome
Narrowed the opportunity to creators with measurable recurring income and defined underwriting as the next proof gate.

Case 02/AI & Data/Proof Engine project
AI sales qualification assistant
A focused AI qualification workflow tested before committing to a broad sales-automation platform.
Challenge
Prospects had to trust the interaction and sales teams had to find the resulting handoff useful.
What we did
Built two conversation flows, tested three positioning variants, and generated structured sales-ready handoffs.
Outcome
The shorter flow won, shifting the product toward a qualification layer before human sales rather than an AI replacement for sales.

Case 03/AI & Data/Proof Engine project
AI workflow automation prototype
Proving one high-value operational workflow before expanding into a broad automation platform.
Challenge
General interest in automation obscured which workflow was urgent enough to adopt and pay for.
What we did
Mapped operational pain, selected a narrow workflow, built a human-reviewed functional prototype, and tested positioning by segment.
Outcome
Proved workflow feasibility and clarified the segment, leaving a live-team pilot as the next evidence gate.

Case 04/Legal & Professional Services/Proof Engine project
Legal operations AI workflow pilot
A controlled legal-operations workflow replacing fragmented AI experimentation.
Challenge
A professional-services team needed repeatability, human review, and a safe integration path before production adoption.
What we did
Mapped the legal workflow, designed review gates, prototyped the AI-assisted flow, and defined the tool-aware integration architecture.
Outcome

Case 05/AI & Data/2019
Customer empathy detection
A self-funded computer-vision concept for estimating customer emotional response in offline retail.
Challenge
Turn an ambiguous human signal into a testable face-and-video analysis workflow without claiming a validated empathy model.
What we did
Designed a webcam-based capture and ML/CV analysis architecture for retail interactions and documented potential store, bank, and call-center scenarios.
Outcome
Produced a presentation-ready architecture and proof concept; no trained or deployed production model was claimed.
Public case
Case 06/Consumer & Hospitality/2013–2014
easy10 language-learning platform
A language-learning product built around ten words a day.
Challenge
After iOS 7 disrupted the early app for roughly one in three users, the product needed a full mobile rebuild, scalable backend and data processing, and a delivery team.
What we did
Designed and prototyped the architecture, implemented redundant high-load infrastructure, rebuilt iOS and Android apps, assembled the team, and supported business development.
Outcome
Reached 200,000 users in the first three months; later public reporting recorded more than 500,000 downloads and about $450,000 in seed investment after a three-month IIDF accelerator.

Case 07/Real Estate & Proptech/2015–2023
RedSwan tokenized real estate marketplace
From a privately distributed iOS property app in 2015 to the investor platform for a tokenized commercial real estate marketplace, designed end to end by one technical product manager.
Challenge
RedSwan needed to put real estate in front of its investors, first as a mobile app and then as a web platform built around tokenized offerings.
What we did
Shipped a privately distributed iOS app in 2015, then designed the platform from zero in 2018: investor cabinet, property listing and every flow between them. Led it as technical product manager, hiring and directing two developers inside a four-person team.
Outcome
A working platform for RedSwan's marketplace and a collaboration that ran until around 2023. Payments were deliberately left out at that stage so the flows could be tested first.

Case 08/Fintech & Crypto/2017–2018
Giga Watt mining-facility operations platform
One operations layer for distributed crypto-mining facilities.
Challenge
Monitoring, pool control, efficiency, and stock management were fragmented across a distributed physical operation.
What we did
Designed, developed, and implemented the software management system spanning facilities, devices, pools, efficiency, and inventory.
Outcome
Created a unified operational view for site operators and owners of hosted mining equipment across facilities, devices, pools, efficiency, inventory, and customer dashboard functions.

Case 09/Real Estate & Proptech/2026
Architecture and expert review for an AI product launch
A startup studio’s AI service built through architectural judgment, security engineering, a professionally reviewed Codex Security audit, and expert review of copy and optimization.
Challenge
The client supplied the concept and brief. The service needed a coherent architecture for private data, paid AI operations, controlled growth, and a credible public launch.
What we did
Designed and implemented the architecture, access controls, paid processing, and operating foundation. Security review combined Codex Security with professional assessment; copy and optimization also received professional review.
Outcome
Delivered a functional service with durable processing, tested access and accounting boundaries, reviewed public content, and search, communication, and operating foundations for GTM.
