I design and build web and mobile applications.

, I’m Vincent Mukuna, a Full-Stack Software Engineer. If you’re building a web or mobile app, or need help with one you already have, I’d be happy to work with you.

Lately, I’ve also been exploring AI agents and how they can make everyday work easier.

Selected work

A few products I've helped design, build, and improve.

AmpleLeads

A lead-generation platform where teams run scraping jobs against sources like Apollo to collect leads.

I built the core customer application in about a week, taking an early prototype toward launch with authentication, Stripe billing, team access, API access, and the lead-request flow. I also fixed plan switching so upgrades and downgrades update the existing subscription instead of deleting it and starting a new one. After launch, I stayed on to improve subscription management and add referral tracking.

AmpleLeads has reported $50K+ in monthly recurring revenue.

StockMarketGuides

A stock research platform where investors screen and score potential trades, with filters for price, sector, and timeframe.

I joined the team on a contract to redesign the customer dashboard and owned it through release. Since then I've kept shipping on the live product: letting monthly subscribers upgrade to annual plans from their account, improving onboarding and notifications, and adding error tracking so the team can see production failures as they happen.

The redesigned dashboard is now the default for customers and has been well received.

BetterFlow

Booking, business management, and payments for service businesses, across web and mobile.

I built much of BetterFlow alongside its founder, from the early product through launch. My work covered public booking, business dashboards, React Native mobile apps, backend workflows, and Stripe payments, connecting customer records, schedules, estimates, and invoices. As the product grew, I helped onboard another developer and carry the release forward.

Live on the App Store and Google Play.

KibbeAI

An AI fashion assistant where people describe what they're looking for and explore matching products.

I shaped the product’s early design and built the frontend, bringing conversational search, recommendations, and product details into one shopping experience.

Within a month, users were trying the first prototype.

Independent projects

My own apps and experiments, built around problems I wanted to solve and ideas I wanted to explore.

Owwed

A private app for tracking debts, repayments, and reminders. I designed, built, tested, and released it on the iOS App Store.

VChat

179

A messaging app with 1,500+ registered users, built for direct and group conversations.

Oak & Pine

A public demo I designed and built, connecting a customer website, staff back office, and AI agents for booking and support workflows. Staff can review proposed changes, approve them, or take over the conversation.

How I work

I came into development through UI/UX, so I pay attention to the gap between a feature that technically works and a product that makes sense to users. I clarify the workflow, surface the edge cases early, and make technical calls based on what the product needs to achieve. On AmpleLeads, that meant catching that switching plans was deleting customers' subscriptions, and recommending we keep database-level access rules in place when it would have been quicker to switch them off.

I can own a meaningful part of the problem and leave behind software that's easy to use and easy for the next developer to extend.

How I work with AI

What I can help with

“I have something in mind. Where do I start?”

Start with what you have. An idea, prototype, or a few screens is enough. I can help shape it into a focused first version and build it from there.

“It’s working, but it could be better.”

I can get into the codebase, understand how it fits together, and help with the next feature or the workflow that keeps getting in the way.

“Could AI take some of this off our hands?”

There's probably more of this you can hand off than you think. I build custom AI agents and connect AI from providers like OpenAI to the tools and data you already use, so your team spends less time on repetitive work and more time on what needs them.
