ekaresearch.orgDon't take my word for it
Jaysi rebuilt our website from the ground up. It finally looks like the company we are — modern, fast, and easy for our customers to use.
Clear communication from day one. We saw designs before any code was written, and the site launched exactly as promised.
He understood that we needed more than a website — an organised platform for our research and publications. Delivered professionally.
Orders that took twenty minutes in a paper book now take two in the app — creation, scheduling, and reports, all in one place.
Months after launch he still answers within a day. Updates, fixes, small improvements — it feels like having a developer on the team.

Not sure which fits? Tell me what you're trying to do — I'll recommend the simplest option, even if it's the smaller one.
Questions businesses ask me
How much does a website or app cost?
It depends on scope — a business website is a much smaller project than a two-sided mobile app. After a free discovery call I'll send you a fixed written quote, so there are no surprises and no hourly meter running.
How long will my project take?
A typical business website takes 2–4 weeks. Mobile apps usually run 6–10 weeks depending on features. You'll get a timeline with milestones before we start, and weekly demos so you can see progress yourself.
I'm not technical — is that a problem?
Not at all; most of my clients aren't. We talk about your business and your customers, in plain language. I handle the technical decisions and explain the trade-offs only when they affect your budget or timeline.
What happens after launch?
I don't disappear. Every project includes post-launch support for bug fixes, and I offer ongoing maintenance for updates, new features, hosting, and app store releases.
How do we communicate during the project?
Whatever works for you — WhatsApp, email, or calls. You'll hear from me at least weekly with a demo or progress update, and I reply to messages within 24 hours.
Have a project in mind?
Tell me about your idea and I'll get back to you within 24 hours with a plan, a timeline, and an honest opinion.
