Taking on new projects

I turn ideas into working digital products.

Android apps, web apps, backends and Android security assessments. Tell me the idea, and I'll take it from first sketch to a product people can use.

Things I've built

Real apps, built end to end. Open a case study to see how each one works.

Zana

Where landlords and tenants find each other.

Zana connects people looking for a home with people renting one out. Tenants search and filter listings. Landlords post properties with photos, prices and details.

  • Kotlin
  • Firebase
  • Cloudinary
  • Paystack
  • Vercel
  • Separate sign-up for tenants and landlords, with email or Google
  • Search, filters and favorites for tenants
  • Landlord dashboard to add and edit listings with photos
  • Pay-to-connect: contact details unlock after a secure Paystack payment
  • Ratings and written reviews
  • Report button for trust and safety
  • In-app inbox and a notice banner the owner can update anytime
  • Terms and Conditions accepted at sign-up
Read the case study

How it was built

  • Native Android in Kotlin
  • Firebase for accounts and data
  • Cloudinary for listing photos
  • Paystack payments checked on a private server on Vercel, so contact details unlock only after a confirmed payment
  • A separate web admin dashboard, so the owner can change fees, edit notices and manage listings with no technical skill

What it shows I can build

Marketplaces, listing and directory apps, pay-to-connect or booking apps, and simple admin tools that non-technical owners can run themselves.

TheftGuard

When someone grabs your phone, TheftGuard takes over.

Arm it once, and it sounds the alarm, alerts your contacts and shows you where your phone is.

  • Kotlin
  • Firebase
  • Cloudinary
  • Fingerprint or face to arm and disarm
  • Live GPS tracking from another device
  • Loud alarm with a spoken warning
  • Silent photo of whoever is holding the phone
  • Emergency SMS with a map link
  • Fake “powering off” screen while it keeps running
  • Restarts itself after a reboot
  • Uninstall and settings protection
Read the case study

How it was built

  • Native Android in Kotlin
  • Firebase for sign-in, live location and syncing across devices
  • Cloudinary for storing the photos
  • Works offline and uploads when signal returns

Why I built it

Phone theft is common where I live, and I wanted a real answer to it. TheftGuard is recent, and I haven't launched it fully yet, because a proper launch needs a budget I'm not putting in for now. I'm introducing it to my audience first and seeing how it goes.

It's up for sale. If you can move fast and have the resources to take it to market, you can buy it outright, and I'm open to other arrangements too. If it stays available, I may put my own focus behind launching it myself. I believe it can be very effective in my part of the world.

Trace

One search box for the public web.

Trace is a mobile-first web app that searches publicly available web results by image, full name, username, phone number, email or domain. It has no accounts, no saved history and no database.

  • HTML
  • CSS
  • JavaScript
  • Vercel
  • Tavily
  • SerpAPI
  • Six search modes in one place
  • Dark, futuristic design made for phones
  • Privacy-first: nothing about a visitor's searches is stored
Read the case study

How it was built

  • Plain HTML, CSS and JavaScript front end, so it loads fast
  • Hosted on Vercel, deployed from GitHub
  • Web results through Tavily and image results through SerpAPI, with both keys kept private on the server

Zana belongs to a client and is not for sale, but I can build something similar for you.

What I can build for you

From a first idea to a working product, or a fix for something you already have.

  • Android apps

    Native Android apps built in Kotlin, from the first screen to a working product.

  • Web apps and websites

    Fast, mobile-first web apps and websites that work well on any phone.

  • Backend, Firebase and APIs

    Accounts, databases and the server side that makes an app work, including Firebase and API connections.

  • Payment integration

    Paystack payments that are checked on the server before anything unlocks.

  • Fixing and improving existing apps

    Bug fixes, new features and cleaner screens for an app you already have.

  • Custom marketplace apps

    Listing and pay-to-connect apps like Zana, with an admin dashboard you can run yourself.

  • Technical consulting

    Talk through your idea and get clear direction on how to build it.

Discuss Your Project

Android Reverse Engineering & Security Assessment

I analyze Android applications at the APK, DEX and Smali levels to understand how they work, identify weaknesses, investigate security controls, and help developers strengthen vulnerable implementations.

What I assess

  • Android apps, at the APK, DEX and Smali level
  • How the app handles login, permissions, protections and sensitive features
  • A clear write-up of what I find, with recommended fixes

Outside my scope

  • Server-side and backend systems
  • Apps built with Flutter

Example: TheftGuard subscription security

I analyzed my own app, TheftGuard, at the DEX and Smali level to test how well its subscription system holds up.

How I build

From your first message to handover, this is how a project runs.

  1. Listen

    You explain your idea in your own words.

  2. Understand and strengthen

    I make sure I fully understand it, then help you strengthen it. That includes suggesting useful things you didn't think of.

  3. Design first

    I start with what you'll see. If you already have a design in mind, I follow it. If not, I research UI inspiration and shape a look that fits your idea.

  4. Set up

    I prepare the backend and the tools your app needs.

  5. Build

    Now the coding begins.

  6. Test, then test again

    I test it myself first. Then dedicated testers go through it thoroughly, and I fix everything they find.

  7. Your review

    When the app looks right, it comes to you to check.

  8. Handover

    Once you're happy, we move to payment. After payment, I hand over your project. Support afterwards, and even promotion, depend on what we agree at the start.

I don't spend a long time on what can be done quickly, and I don't rush what needs time to be done properly.
