01 / A SELECTION OF WORK
Work that speaks.
A curated look at SaaS products, Shopify systems, commerce platforms, AI tools and open-source packages I engineered or led technically.
02 / ENGINEERING IN PRACTICE
Beyond the feature list.
Three examples of the constraints, architecture and operational thinking behind my work. Details reflect projects in my CV.
02 / SHOPIFY
100+ catalog checksPreventing risky bulk edits
VeriCatalog combines deterministic checks, incremental scans and guarded fixes with preflight checks, verification and audit trails.

11 backend domainsMaking asynchronous work predictable
Tik Video spans multi-provider AI generation, queue orchestration, callbacks and credit settlement with explicit failure handling.

03 / HOW I CAN HELP
Engineering that moves products.
From architecture decisions to the messy production details, I work where backend reliability meets business-critical workflows.
Laravel & SaaS architecture
Modular backends, multi-tenancy, permissions, subscriptions and API contracts that can grow with your product.
Shopify & payment systems
Shopify Admin GraphQL, webhooks, checkout integrations, wallet flows and safe transaction state handling.
Production audits & recovery
Query bottlenecks, queues, idempotency, race conditions and failure recovery in systems that cannot afford surprises.
Filament & business operations
Admin panels, internal tools, approval workflows and business integrations designed for the people running them.
04 / BEHIND THE CODE
More than code.
I care about how systems behave on their worst day, not just how they look on a successful demo.
THE PERSON BEHIND THE PRODUCT
I build the systems that make ambitious products possible.
From multi-vendor commerce and EdTech to AI-powered SaaS and payment orchestration, my focus is the engineering foundation: clean boundaries, resilience, maintainability and measurable outcomes.
