One connected experience
My work spans welcome and onboarding, exercise and running modes, music playback, AI coaching and the interview after an athlete's training session. The goal is to make training, guidance and music feel like one product.
Engineering and product ownership
I developed the application and supporting services alongside the interactive-audio technology. The music work uses Rust/WASM and native audio tooling; the granted patent is documented in a separate portfolio entry.
Product storytelling
I directed and produced the attached advertisement in collaboration with our editor. The homepage pairs product positioning with a scroll-driven phone demonstration and video-led creative.

Through inKibra, I personally won the Mercury Build engagement, agreed an expansion after the initial contract, and partnered with a director at a major Pacific Northwest contractor to deliver the system. My work spanned product decisions, full-stack implementation and deployment. Mercury brings configurable forms, branching logic and visual workflows into construction management.

Won the engagement, then expanded it
I personally closed the initial engagement, which ran for roughly four months, before agreeing an expansion that lasted roughly nine more months. At $25,000 per month, the work generated approximately $300,000 in engagement revenue. My role combined the client relationship with hands-on product and engineering delivery.
Build around the actual process
I partnered directly with a director at the contractor, connecting product decisions with hands-on engineering across construction-management workflows, implementation and deployment.
Tools the team can adapt
Public demos show a visual template editor, branching logic and custom workflow configuration, letting teams tailor information collection and handoffs between steps.

From design intent to instructions
My contribution centered on measurements, design decisions and iterative review: challenging ambiguous illustrations and asking for CAD-linked dimensions, raw-stock allocation and explicit checks. Codex assisted implementation; JSCAD and renderer libraries provide geometry and visualization. Specific personal code authorship is not established by this evidence.
A component you can trace
The 70-second TV stand recording follows EB1/EB2 from CAD through guide regeneration, inventory, cut layout, routing and end-frame assembly. It is real browser execution, silent and unshortened. The project-specific guide generates on page load; this is not a generic convert-any-CAD tool.

Evidence and limits
These are actual schematic CAD renders, not finished-build photographs. Exploded offsets show component relationships, not fastening order. Casters and hardware fit remain provisional; selected geometry checks do not establish structural approval, physical-build validation, novice usability or time savings. Guide callouts retain documented crowding and labeling limitations. The downloadable guides are evidence, not manufacturing-ready plans.

At Google, I worked on local-answer actions for calling, directions and food ordering, Geo speech, and new ways to discover places. I also won three Google hackathons: recovery for misunderstood voice queries, a multi-stop journey planner, and taste-based local search with shareable collections. These images are illustrative recreations of my contributions, not original Google screenshots.

Plan a sequence, not three unrelated searches
The journey-planning concept let a person lock a first stop, search around it for a second, then continue from the second location to a third. Three horizontal cards kept the evolving plan visible alongside search and the map.
Search with a shared sense of taste
I worked on using a collection or taste signal as an input to local search, including combining it with a friend's preferences. I also contributed to explanations of why a result fits.
Recover a spoken request
My hackathon work addressed misunderstood audio queries with a clarification rather than a dead end. The confirmed showcase surface was a screen-equipped Google Home device, and the owning team subsequently shipped the recovery feature.
Separate speech contributions
Geo text-to-speech reliability was another contribution, distinct from recognizing and recovering incoming spoken queries.

A recovery interface, not universal reversibility
The proposal explores a common interface for recoverable tokens. It is a proposed ERC, not an adopted Ethereum-wide standard.

Filipe F. Martins, David R. Matos, Miguel L. Pardal and Miguel Correia documented a recoverable-token implementation in their IEEE NCA 2020 paper. Their implementation is independent work.

Joined immediately after the acquisition as one of three backend engineers turning the Luxe car-movement engine into Volvo service infrastructure — re-architecting backend workflows so the startup's valet engine could power Volvo's consumer service flows, the service foundation for the Polestar launch.
Led the SDK-first refactor (TypeScript AST codemods) that drew a clean API boundary between the backend and the five-person frontend team — unlocking parallel frontend development, eliminating duplicated code and cyclic dependencies, and introducing a Cap'n Proto / GraphQL–inspired pattern for bundling API calls.
Built the localization workflow (GitHub Actions, Docker) used by the Luxe and Volvo On Call teams; advised European GDPR and Chinese data-compliance architecture.

Engineering Team Lead & Senior Full Stack Developer
Architected the microservice framework, self-documenting protobuf-inspired RPC tooling, and WebRTC-based sub-second event streaming that let live polls and chat games track the broadcast in real time — the show's engagement engine.
Led a six-person engineering team across React Native apps, release workflows, and FFMPEG/CDN/Wowza video pipelines on AWS with Terraform, Docker, and Consul.
Owned hiring — designed a methodology of phone screens, coding challenges, and team interviews, and grew the team by two engineers.
Helped set up and produce the end-of-season live show streamed by Usher — including firefighting a last-minute streaming-vendor settings change as the broadcast went live.
Led product development of a machine-learning social-media usage optimizer for brands and influencers — interviewed external stakeholders to identify market needs and opportunity size, collaborated on the business plan, and presented recommendations to senior management.
Architected TypeScript microservice APIs with ledger-based data models, generated clients and SDKs, JWT authentication, and enterprise partner integrations.
Built a finite-state-machine tester proving complete state-transition coverage; owned cloud-security — managing a PKI and secrets with Vault and Keybase and setting the developer toolchain and best practices.
Contributed to the product roadmap with a component-based workflow-composition UI that sidestepped rules-engine complexity entirely — ASN.1/PKCS#7 for security, multi-part messages for legacy compatibility and extensibility.
Named inventor on Trunomi's 2017 consent-management filings — obtaining and releasing personal information under explicit user authorization, years before the privacy-compliance category consolidated around the same problem.

Authored EIP-1080 (Recoverable Token), an early complete interface for recovering lost or stolen tokens at the contract layer — engaging the Ethereum community and the Kleros arbitration network on game-theoretic griefing constraints. Researchers at Instituto Superior Técnico, University of Lisbon built the first full implementation of it, naming their IEEE paper after the proposal and benchmarking its exact function calls.
Led Horizon Games' scaling research and early prototypes — account-based Plasma, Tendermint-style consensus, a TypeScript/WebAssembly sidechain with a two-way Ethereum bridge — work that fed the core technology that became Sequence, the wallet platform now powering millions of onchain interactions.
Consulted for Bitfinex/Ethfinex on market-making incentives — built the reference solution on the 0x protocol with token auctions and a fee-collecting ERC-20.
Audited the designs that preceded Bitfinex's production Nectar token — eliminating reentrancy and overflow attacks, with simulation mocks to tune parameters against griefing and sybil attacks.
Built Smaato's first self-service ad-tag creation flow (React/Node, designed end to end) so clients could configure tags for any SDK without sales-engineer help — plus malicious rich-media testing pipelines, OpenRTB bidder integrations, and VAST compliance automation.
Migrated MSMCI's AWS infrastructure to a new account within 24 hours with zero app downtime, using Terraform, Consul, and Docker.
