Senior Full-Stack Developer

Web Applications & API Integrations

I combine technical architecture with hands-on application delivery, backed by 7+ years of experience. My work includes more than 10 client applications and enterprise deployment tools for Roche. My web stack includes React, Vue, Angular, and TypeScript.

Start with the whole system.

The starting point was an existing FlutterFlow app with stability and usability problems. The client needed a better experience quickly.

The mobile app shared its Xano backend with other interfaces. A broad architecture change would affect more than the app.

Improve the experience within the constraints.

I reworked the Flutter app and its backend integration while keeping the shared architecture in place.

The work covered authentication, tasks, messages, events, and college workflows. I focused on clearer navigation, consistent screens, and responsive interactions.

I worked directly with a non-technical client to clarify requirements. I explained technical constraints in plain language and turned the discussions into practical changes.

Deliver, then stay involved.

The initial app and backend rework took about three weeks. The client was happy with the delivery, and the work moved into ongoing maintenance.

The app supported hundreds of U.S. students. The result was a clearer experience built around their day-to-day tasks.

Shopping integration

Join systems that already had different jobs.

Cysterhood needed an in-app shopping experience within an established React Native app.

One WordPress site managed membership. A second site ran WooCommerce. A Django backend and MongoDB supported the app.

The challenge was to connect these systems while preserving the existing membership and commerce flows.

Make shopping feel like part of the app.

I delivered product browsing, product details, a cart, and checkout inside the app.

The integration connected the mobile experience to the existing WordPress and WooCommerce systems. I handled the session handoff needed to keep the journey connected.

I delivered the shopping integration in two weeks.

Keep improving after delivery.

I used Crashlytics reports to investigate problems on different devices.

I also added shopping analytics and Iterable events for product views, cart activity, and checkout starts.

This gave the team a way to inspect the shopping journey and investigate problems after release.

An immediate deadline.

SmartOne needed its merchant portal redesigned for a customer presentation. The portal accompanied its point-of-sale terminals.

I joined with little time to get comfortable. The existing frontend had inconsistent styling and substantial inline CSS.

Create a system, then apply it.

I built a shared UI library and used it to bring the portal into a consistent design.

I consolidated repeated styles and components so the redesign could move across the portal quickly.

This work took place before AI coding tools were part of my workflow.

Turn an urgent task into a longer collaboration.

I delivered the portal redesign in ten days for the customer presentation.

The successful delivery led to further development work with SmartOne. The shared UI foundation supported that continued work.

Comparison prototype

Learn the domain before changing the rules.

Roche needed new features within its Codebeamer environment. The work involved project configuration, workflows, and deployment rules.

I worked closely with client requirements and learned how the existing deployment process operated.

Turn requirements into enforceable behavior.

I implemented safeguards that block conflicting deployment actions before execution.

The checks considered related deployment activity and stopped an action unless the system explicitly allowed it.

I documented the decisions and their constraints so the team could review the behavior.

Make configuration differences visible.

I also built a standalone prototype that compared stored configuration revisions, including fields, permissions, and workflows.

The comparison work remained a proof of concept. It gave the team a concrete implementation to review.

Clear rules, working safeguards, and a concrete prototype for the next decision.

Bring me in when…

The product needs a fresh start.

I work out what needs to change, improve the user experience, and fit the changes around the systems already in use.

The systems need to work together.

I connect the parts behind a product so people can complete a task without dealing with the complexity underneath.

The deadline is already close.

I get clear on the priority, make practical technical decisions, and build a consistent foundation that helps the work move quickly.

Good software starts with understanding the problem.

I start by understanding what people need and how the existing system works. With non-technical clients, I explain the options in plain language so we can agree on practical changes.

I stay close to the work—from architecture and implementation to release and maintenance. I care about a clear experience for the people using the product, and a codebase the team can keep improving.
