Get found by people already looking
Most customers search online before they call. A website puts your business in front of them when they need you — through Google, local maps, and word-of-mouth links.

Developments
Professional websites, built one-on-one, shaped around your goals and budget.
I design and build custom websites for small businesses — the shops, trades, studios and practices that deserve better than a template nobody maintains. You work directly with me, start to finish.

The value of a site
A website is not an expense — it is the hardest-working part of your business.
02
Build trust in seconds
A clean, professional site tells visitors you are serious before you say a word. Photos, reviews, and clear contact info turn skepticism into confidence.

Turn visitors into real leads
Forms, phone numbers, and booking links work while you do. Your site becomes a quiet salesperson that never clocks out.

Control the story
Social pages change their rules and bury your posts. Your own website is yours — it shows exactly what you want, how you want, for as long as you want.

What's included
Everything a small business site actually needs — and nothing it doesn't.
Custom Design
A layout drawn around your business — your colors, your photos, your words. Nothing off a shelf that a hundred other sites already use.
Mobile-First Build
Most of your customers arrive on a phone. Every page is built and tested there first, then scaled up to tablet and desktop.
Ongoing Support
Hours change, menus change, staff change. Send the update and I make it — no CMS to learn, no ticket queue to wait in.
Fast Turnaround
A free demo in days, not weeks. Once you approve the direction, most sites launch inside two weeks.

About
You're hiring a person, not an agency.
I'm Kasey Cosentino, a sophomore at Boston College and the founder of WebSpark Developments. I'm based in Andover, Massachusetts, and I build websites for small businesses — every page designed, written into code, and launched by me personally.
Small businesses are usually stuck choosing between an expensive agency retainer and a do-it-yourself builder that ends up half-finished. I started WebSpark to sit in between: a genuinely custom site, at a price that makes sense for a local business, from someone who answers the phone when you call. You'll never be handed off to an account manager or wait a week for a two-minute change.
What I care about most is the long relationship. A website isn't finished the day it launches — hours change, services expand, photos need swapping. The yearly plans exist so that maintenance is simply part of the deal, and so the site still looks current three years from now.
Client Work
