Featured Projects
LineupOps
Two-sided B2B SaaS for the print-on-demand industry — connecting online sellers with the warehouses that print and ship for them. An order placed on Etsy flows in automatically, routes to the right warehouse, gets batched, printed, and shipped, and tracking flows back to the marketplace — nothing manual in between. ~105k lines of code across 5 deployed applications: marketing site, seller portal, warehouse portal, and two backend services. Includes an in-browser design studio (fonts, layers, print-safety checks), Stripe subscriptions and Stripe Connect payouts with append-only wallet ledgers, white-label portals per warehouse on their own subdomains, and Etsy / Shopify / Amazon SP-API integrations. Tenant isolation enforced with PostgreSQL row-level security; every write idempotent; 200+ automated end-to-end tests against the deployed environment.
Pistabella OS
A consumer food brand's entire back office, rebuilt as one custom cloud platform — scoped and built directly with the client, deployed to production on Railway. Eleven modules on shared data replace the spreadsheet stack: CRM pipeline, wholesale orders, international shipments with landed-cost tracking, invoicing, P&L and 13-week cash-forecast reporting, expenses, HR & payroll (AU + US), products, research, and tasks — plus a ten-widget daily dashboard. 119 API endpoints, 5 enforced workflow state machines, and 10 permission roles. Built to enterprise standards: a tamper-evident hash-chained audit log behind every financial, pricing, and HR write, field-level encryption of sensitive data, refresh-token rotation with reuse detection, and a multi-tenant architecture from day one.
MasalAmca
AI-powered Turkish bedtime stories for children — personalized narration and minimal screen time. Native SwiftUI app (iOS 17+, iPhone & iPad) generates safe, unique stories per child (name, age, themes), narrates them with natural AI voices, and keeps listening friction-free with background playback, lock-screen controls, optional white noise, and a saved-story library. Shipped with SwiftData, OpenAI GPT-4o-mini, Gemini Flash TTS, a Cloudflare Worker proxy for auth, rate limits, and server-owned prompts, plus RevenueCat and StoreKit 2 — a production App Store product focused on imagination-first, screen-optional listening.
Lullaby: Baby & Bump Tracker
iOS companion for pregnancy through early childhood: feeds, sleep, diapers, health notes, growth, and milestones. Caregivers log in seconds from the dashboard; data stays on-device and syncs through private iCloud (SwiftData + CloudKit) — no custom backend or third-party trackers. Soothing lullaby playback with background audio and lock-screen controls for calm routines. Native SwiftUI (iOS 17+, watchOS, widgets, App Intents), strict Swift 6 concurrency, accessibility-minded UI, and RevenueCat for Lullaby Plus — a production App Store product for privacy-sensitive families.
RAG4PDF
Production SaaS for cited, grounded answers from your own PDFs via a multi-agent RAG pipeline. Users sign in with Google, configure AI agents (each with its PDF library and optional persona), and chat with responses that reference exact book and page; sources open the PDF at the cited page in the browser. Features parallel hybrid retrieval (vector + full-text), query expansion, passage reranking, NLI-based grounding checks, and async answer evaluation per agent; multi-stage ingestion with background jobs into PostgreSQL and pgvector; Stripe billing with idempotent webhooks and a local mock path; Google OAuth with JWT and shared-agent demo links. Spring Boot 3.5 / Java 21 backend with LangChain4j and OpenAI, React / TypeScript frontend with SSE for ingestion status and a full billing UI — deployed on Railway with Docker Compose for local development.
