Case studies
Every entry here is a production system that shipped and stayed in service: healthcare integration, document pipelines, AI agents, e-commerce, mobile, and the operational platforms in between.
The heaviest work sits in healthcare integration: FHIR R4 platforms, HEDIS pipelines, clinical document OCR. Around it are the AI agents, storefronts, and internal tools that keep client operations running. Standards deep-dives and architecture notes live in Insights.
Multi-clinic web platform
Multi-tenant Next.js framework that launches ADA-compliant, HIPAA-aware clinic websites from one shared codebase. Each location gets its own subdomain, branded theme, appointment widgets, and secure intake forms without a separate build per site.
FHIR · TEFCA · USCDI integration
Production FHIR R4 server covering 42 resource types, SMART on FHIR v2.1 with PKCE, TEFCA QHIN handshake against Epic Nexus and CommonWell, and a tamper-evident audit chain scoped to the Consent that authorized each read. Passed external info-blocking review without remediation.
HEDIS measurement pipeline
HEDIS measurement pipeline built on .NET Windows services: fax intake, insurance portal sync, document classification, retry queues, and Slack-native incident routing tied to stuck-order diagnostics. HEDIS submissions reproduce on demand from raw inputs to final measure.
Clinical document watcher
Fleet of .NET clinical document watcher agents running unattended at provider endpoints. Each agent detects signed documents, OCRs where needed, and pushes to a central store with chain-of-custody hashing. Buffers locally on outage and resumes without duplicates.
Tool-use agent · production
Production LLM agent with typed tool catalogs, structured-output validation, per-tenant billing meters, and a reviewer loop that catches bad tool calls before they reach customer-facing systems. Model-provider swap is a config change, not a rewrite.
Image classify and OCR pipeline
High-volume image classification and OCR pipeline with GPU-aware batch scheduling and a variable worker pool. Structured clinical data extracts route downstream with content-hash deduplication. Survives bursty load without losing a frame.
Trading operations terminal
Internal orchestration platform for dozens of trading bots across dozens of servers. Python strategy DSL, parameter validation at admit time, live PnL telemetry over WebSocket, Telegram on-call paging. Monthly turnover in the millions, ops team of one.
Healthcare SEO program
Technical SEO program for clinical sites. JSON-LD schema markup for MedicalClinic, Physician, Service, and MedicalProcedure, Core Web Vitals optimization, hreflang for multilingual content, and GSC instrumentation that surfaces ranking drops before they compound.
Social production pipeline
Content production pipeline for healthcare and personal brands. Automated cross-platform scheduling, AI-assisted caption reformatting, brand-safety gate before publish, and unified engagement reporting. One creator, many channels, no copy-paste.
Pre-owned car marketplace
Two-sided marketplace for pre-owned cars. Buyer-side Elasticsearch search tuned to category intent, VIN decoding, dealership onboarding, condition reports, financing match, escrow flow, and fraud signals at the listing layer before any inventory goes live.
Scan and fax image enhancement
Server-side enhancement pipeline for medical document imaging. Deskews, denoises, and normalizes contrast on scans and inbound faxes, then scores OCR readability before any document reaches the clinical record. Persistent failures escalate automatically for human review.
Document reformat at scale
Memory-bounded streaming pipeline that converts clinical document corpora across PDF, TIFF, DOCX, structured XML, and clinical CDA. Structure survives format hops. Every transformation step writes an audit record with input and output hashes for replay.
Mobile medication selector
Patient-facing iOS and Android medication selector app built for a real symptomatic moment. Indication search, drug interaction and contraindication checks against the FHIR-backed patient profile, OTC versus Rx routing, and a Mapbox pharmacy locator.
International logistics console
Operations console for cross-border freight forwarding built around real domain jargon. Carrier API normalization, customs documentation, route-exception detection, broker handoffs with ownership transfer, and finance reconciliation tied to invoice line items.
WordPress site fleet
Tens of WordPress builds across realtors, clinics, politicians, retailers, and B2B e-commerce. Custom themes, ACF and Gutenberg block libraries for editors, WCAG 2.2 AA accessibility, and LiteSpeed-tuned hosting under contract. Editors run their own sites.
Shopify apps and storefronts
Custom Shopify app development for indie brands and growing retailers. Private apps for back-of-house automation, public App Store apps with OAuth and billing, headless storefronts on Hydrogen, and theme work where it earns its place. Built so the merchant runs the day to day.
Native and cross-platform mobile apps
Native and cross-platform mobile apps across consumer, healthcare, and enterprise. Offline-first sync, push and live activity, in-app purchases, biometrics, and secure storage. CI signing is wired so App Store and Play Store updates ship without an engineering escalation.

Billing and account-management software for regulated energy distributors and retailers. Tariff calculation engine, meter intake from physical and remote channels, multi-channel customer notifications, and regulator-aware reporting integrated with national clearing pipelines.
Multilingual clinic platform
Multilingual web platform for a private multi-location medical center serving the Eastern European diaspora. i18n routing in Polish, Ukrainian, and Russian, a multi-step appointment wizard wired to an external booking API, and native medical terminology across all locales.
Automated medical reporting
Branded PDF report generator for clinical workflows. Templated layouts, dynamic chart binding, signature blocks, batch generation against patient cohorts, locale-aware content, and a downstream distribution integration. Replaces hand-built Word documents for ops teams.
HIPAA audited file proxy
Authenticated HIPAA-compliant file delivery proxy for clinical documents. Tokenized URLs scoped to one document, one recipient, and one time window. Virus scanning before delivery, configurable retention per partner, full audit trail. Passed external HIPAA security audit on the first review.
Clinical data warehouse
Long-running clinical data warehouse on MSSQL. Patient, encounter, and claim records normalized with full history, idempotent ETL batches against external partners, code-managed stored procedures, and read-only replicas for analytics teams. Survived years of feature work without losing referential integrity.

Map-based geo-resume platform
Map-based platform for location-aware professional profiles. Candidates pin an availability radius, recruiters search by proximity or travel-time isochrone, and branded micro-sites per region drive local SEO. Built on the Google Maps API with custom clustering and geocoding cache.
Dating platform, agency-led
Two-sided agency-led dating platform with distinct workspaces for matchmakers and members. Agency-side profile curation and managed introductions, member-side KYC onboarding, moderated messaging, WebRTC video meet rooms, and a multilingual interface for international clientele.
Construction company sites, multi-country
Multi-country website framework for construction firms. Per-region branding, project portfolios with rich media, localized content and units of measurement, and quote flows that route leads to the right regional office by visitor location. Shared codebase, distinct themes per market.
Artisan salt store with recipe content
Shopify storefront for a small-batch culinary salt brand with author-led recipe content. Custom Liquid theme links recipes to ingredient products, structured Recipe schema earns rich snippets in search, and the founder publishes content and ships orders without an agency on retainer.
Brand site for a pioneering AR and VR studio
Public brand site for one of the longest-running AR and VR studios in the United States. WebGL teasers load only when visible, interactive 3D set-pieces run on framerate budgets, and the full site loads on conference Wi-Fi without compromise.
