Frontend Engineering.

React, TypeScript, JavaScript & responsive interfaces

The frontend is where a person meets the software. Components, interactions, and data requests need to work together so that a task feels clear—even when the system behind it is complex.

The business context

Interfaces that help people get something done.

A good frontend handles more than its ideal state. Loading, empty results, invalid input, and failed requests all affect whether someone can complete a task. I consider those paths alongside layout, accessibility, and the systems providing the data.

The layers of the stack

The tools and how I use them.

ReactComponent-based interfaces

React

React organizes interfaces into components that respond to data and interaction. It can support an embedded listing as well as a larger application. I look at how state, requests, and rendering fit together so that changes remain understandable across related components.

TypeScriptExplicit data shapes

TypeScript

TypeScript adds type checking to JavaScript, helping describe component inputs, application models, and expected responses. It can catch mismatches during development. Data arriving from an API still needs appropriate runtime handling; a type definition alone does not validate an external response.

JavaScriptBrowser behavior

JavaScript

JavaScript connects user actions to changes in the interface. Events, asynchronous work, and the browser lifecycle matter whether a page uses a framework or a small script. I aim to keep the behavior appropriate to the feature and the environment already in place.

jQuery / AJAXEstablished interactive sites

jQuery / AJAX

Many maintained websites use jQuery and asynchronous requests for forms, filtering, and interface updates. Working with those systems means understanding their event handlers and response expectations. A focused improvement can preserve useful existing behavior while addressing the actual problem.

AxiosHTTP requests

Axios

Axios is an HTTP client used to make requests from application code. Request parameters, success handling, and error behavior need to agree with the API contract. For listings or forms, I trace the request and the resulting interface state together.

CSSStructure and presentation

HTML, CSS & SCSS

Semantic HTML provides structure; CSS handles layout and presentation; SCSS supports organizing stylesheet source. Clear document structure, keyboard focus, responsive behavior, and maintainable styles are part of the engineering work, alongside the visual design.

My approach

Start with the interaction and its states.

I map the interaction’s loading, success, empty, and error states before connecting it to the API. Then I choose the smallest amount of browser code or component structure the feature needs.

Get Network Visibility

My contributions include React resource, partner, and event listing modules, JavaScript, form work, and CSS/SCSS styling. The site also has separate PHP filtering paths. The base theme and framework are credited to FINNPartners.

My work includes MVC/Razor and Kendo UI interfaces for operational workflows. This is another kind of frontend engineering: making interactions agree with server-side rules and the records behind the screen.
