Architect. Builder. Operator.
One person.

Eight years as the exclusive engineering partner of an ACH and digital-check platform: Plaid Link and bank verification, Dwolla transfers, an NMI card gateway and Stripe, merchant onboarding and risk state, and a versioned partner API that other platforms embed. Regulated money movement under live traffic.

A custom platform for a 10,000-SKU fashion retailer that ran fifteen years and its full Shopify migration with SEO equity intact; a multi-vendor US and Canada marketplace; Magento and POS integrations; storefronts for beauty, wine and grocery brands.

Seventeen years with a scoreboard manufacturer: quote and configurator flows on top of a content and CRM platform. Lately a parts-search engine over industrial catalogs, an operator console for industrial machinery, and controller code for factory machines (PLC, Structured Text).

Product engineering for DeFi protocols - liquid staking, governance-incentive marketplaces, tokenized yield, NFT lending - and a web3 security firm: Next.js interfaces with ethers.js and web3.js, wallet integrations, on-chain indexing (Subgraph, Substreams), node operation on AWS.

A search platform on MLS feeds that ran fourteen years: thousands of programmatic pages, an in-house CRM and email automation, organic traffic as the growth channel. Luxury listings and a commercial real-estate investment firm alongside it.

The first AI Engine Optimization platform, built end to end: four apps, crawl and audit workers, an MCP server, a Chrome extension and a WordPress plugin. A multi-tenant AI chatbot and voice platform; Telegram bots and mini-apps; Claude and OpenAI in production, RAG over company data, document extraction at batch scale.

Programmatic SEO, Google Ads and analytics wired into CRMs, per-client tracking scripts served from a CDN, an AI-visibility program that moved a manufacturer's score from 33 to 90, and migrations off WordPress and Webflow onto fast static stacks.

Three properties for one film business - an arthouse cinema, a distributor and a production company - with an online streaming platform on an AWS backend, an admin portal for content and users, and scalable video distribution.

Plaid Link across an ACH and digital-check platform: link-token issuance, re-authentication and update mode for expired items, instant and micro-deposit verification; Dwolla funding sources and transfers, an NMI card gateway and Stripe alongside them - under live merchant traffic and regulated money movement.

Google, Shopify, CRM and ad-platform connections across multi-tenant products: consent flows, refresh-token storage and rotation, per-tenant credentials, and re-auth paths for when a provider revokes access. The clean half of aggregation.

A real-time market-data recorder for a marketplace with no public API: GraphQL operations captured from the web client, authenticated browser sessions, adaptive rate limiting with 429 backoff, anti-bot and fingerprint handling, hundreds of concurrent live streams inside a fixed request budget, evidence behind every recorded fact. Plus collector fleets over SEC EDGAR full-text search, CourtListener, SAM.gov, regulator feeds and MLS.

A versioned partner API (v1/v2) with API-key auth, per-app audit logging and OpenAPI docs, so other platforms could open bank accounts, move money and bill their own customers through ours; a Bearer-keyed public API serving /openapi.json and hosted docs, shipped with a reference client that shows what the integration should feel like; an MCP server, a Chrome extension and a WordPress plugin in the official directory.

The surfaces a customer's own users touch: the bank-connect flow, hosted billing and checkout links partners generate through the API, per-client tracker scripts served from a CDN, embeddable chat widgets and mini-apps - dropped into someone else's product and never thought about again.

AWS, Cloudflare, Docker, Terraform and GitHub Actions; migrations between clouds and onto plain VMs when managed services stop earning their bill; on-prem and hybrid deployments where the data has to stay in the building; Linux administration since the managed-hosting days.

Taking over what someone else left behind: PHP, .NET, Elixir, Go, WordPress plugins, discontinued industrial HMIs. SeamlessChex started as a stalled prototype and stayed for eight years.

Cypress and Playwright end-to-end suites, unit tests as a release gate, infrastructure as code, documentation and handoff - so the system keeps running when I am not looking at it.

Fifteen years hiring and keeping senior squads, up to ten client engagements in parallel, now the same gates run with AI agents alongside me: scoped work, review, tests, deploy. Weekly releases, honest scope before code.
