I turn ideas into complete digital products. The interface you touch, the logic behind it, and the infrastructure that keeps it running.
One engineer.
Every layer, connected.
Clear, considered interfaces that make complex systems feel simple.
Complete systems documented from working code, measured outcomes, and the decisions behind them.
I built a secure operations portal for an Amazon seller management agency, bringing client work, reports, files, product trackers, and conversations into one accountable workflow.
Built for Savvy Ecom Solutions
I designed and built a mobile-first storefront and operations system for a children’s occasion-wear brand, from product discovery and custom sizing to COD fulfillment and first-party insight.
A quieter index of original work across local software, systems tooling, and realtime products.
Local-first point-of-sale desktop and Android app built for a home-based restaurant: menu, orders, receipts, expenses, profit reporting, search, backups, and data migration without an account or network.
Rust terminal downloader with parallel range requests, worker pooling, verified resume manifests, retry backoff, speculative overlap for no-range servers, and a full interactive TUI.
Server-authoritative multiplayer Ludo with Socket.IO rooms, reconnect survival, match history and replay, first-party authentication, rate limits, runtime schemas, and a multiplayer smoke test.
A mechanical study from the workshop. Five gears, one input, every movement connected.
Drag a wheel to take over. Or focus the red drive wheel and use the arrow keys.

At rest
An experiment in connected motion. Built to be played with.
The operating principles behind the systems above.
I keep the product, its failure modes, and the delivery path in one mental model.
I can move from product modeling and interface work through authentication, data, integrations, deployment, desktop packaging, and operational handoff without losing the thread between disciplines.
Passkeys, role-aware mutations, runtime validation, idempotent background work, atomic imports, and verified resumes are designed into the system rather than applied after the interface is finished.
You work directly with the person modeling, implementing, testing, and shipping the system. Decisions remain explainable, and handoff artifacts are part of the build.
Short records of decisions that mattered after the interface was finished.
A hidden button is not a permission boundary. Amazon Portal re-checks the active session, role, and granular permission where each mutation executes, so a stale screen cannot replay authority it no longer has.
Countertop validates a versioned import before it replaces local state, creates a safety backup first, and keeps recovery behavior testable. “Local-first” only earns trust when restoration is designed as carefully as storage.
Parallel downloaders usually assume byte ranges. Blitzer probes that capability, uses verified overlap when speculation is safe, and falls back to a single stream rather than pretending unsupported concurrency is reliable.
A polished catalog is unfinished if every order creates manual chaos. The store and its administration share one commerce model for variants, shipping, coupons, COD totals, reviews, communication, and fulfillment.
One source invariant and a live index of original public work.
export async function requireActionPermission(permission: AdminPermissionKey) {
const user = await requireActionRole('ADMIN');
if (!hasAdminPermission(user, permission)) {
throw new Error('Unauthorized');
}
return user;
}Complete source specimens and implementation notes live inside the case files.
Send the problem, the current constraints, and the outcome you need. A prepared brief is not required. I will reply with focused questions and a practical next step, usually within 24 hours.
