This is good initiative though I haven't tested the tool. I note that I have a collague who makes breaking changes w/o notice. This can be helpful. I can bookmark this and give it a try b4 I give feedback

sure, would be expecting feedback, please star the repo, it goes a long way. thanks 🙏

Audacious for a 17 year old to refer to themselves as a Software Engineer. A programmer? Of course. A software engineer? I highly doubt.

jokes on you, lol
ask google who’s “David Uchenna” if you could ship what i’ve shipped then i’m open to discussing further, else… zip it an go home, lol

feedback would be highly appreciated

engprodigy:
Good job! Quite interesting.

yup, would love your feedback chief

buqi:
I have fresh cucumbers for sale please

You can list them on Flinck, and get instant buyers, here’s a link to downloading the app from playstore https://getflink.pro/download

I also wrote a medium article about it for better understanding https://medium.com/@callmedav/i-built-apidiff-an-open-source-tool-for-catching-api-contract-changes-before-they-break-frontend-79aaf7f4169d

Hi, my name is David Uchenna, a software engineer and founder of Flinck building products from Nigeria. I’m 17 btw

I’ve been spending a lot of time working on backend systems, APIs and developer tools, and recently I decided to build something around a problem I’ve personally seen developers deal with:

Backend API changes breaking frontend applications without anyone noticing.

That’s what led me to build Apidiff.

Apidiff is an open-source API contract diff and monitoring tool designed to help developers detect meaningful changes in API responses before those changes turn into frustrating frontend bugs.

For example, imagine your backend originally returns:

{
"id": "123",
"name": "David",
"phone": "+234..."
}

Then someone changes the backend and suddenly it becomes:

{
"id": 123,
"name": "David",
"phone_number": "+234..."
}

The frontend might break because a field changed from phone to phone_number, or because id changed from a string to a number.

The frustrating part is that you may not immediately know the API contract changed.

You could spend hours debugging your frontend before eventually discovering what happened.

Apidiff is built to catch that.

It works as a local API proxy, observes API responses, builds contracts from them and detects changes between versions. It also includes response normalization and noise filtering so things like dynamic timestamps or request IDs don’t create unnecessary false alarms.

The core is built with Go, and I’m also working on making it easy for JavaScript and TypeScript developers to use without needing Go installed.

The project is open source and available on GitHub:

I’m still actively developing it, so I’m particularly interested in feedback from Nigerian developers and other software engineers building APIs, React/Next.js applications, mobile apps and full-stack systems.

This is one of the things I enjoy most about software engineering, seeing a problem, building a tool around it, and putting it out there for other developers to use.

If you’re interested in what I’m building, you can follow my work here on Nairaland or check out my GitHub.

A Nigerian student developer has officially rebranded his agricultural social marketplace from Flink to Flinck as the platform continues expanding its vision for Africa’s agricultural ecosystem.
The platform, created by 16-year-old software engineer David Uchenna, is designed to help farmers, buyers, and agricultural communities connect digitally.
Unlike traditional marketplaces, Flinck combines:
social interaction
agricultural communities
produce discovery
direct buyer-seller connection
all in one platform.

What exactly is Flinck?
Flinck is an agricultural social marketplace built specifically for agriculture.
Farmers can:
connect with other farmers
share farming updates and insights
list produce for buyers to discover
grow visibility for their products
Buyers can:
discover farm produce
contact sellers directly
explore agricultural communities and discussions
The goal is to reduce fragmentation in agriculture and make it easier for people in the industry to connect and trade.

Why the name changed from Flink to Flinck
According to the developer, the rebrand was mainly done to create a stronger and more unique identity online.
The previous name “Flink” had heavy competition in search results from existing international companies and technologies.
“Flinck” gives the platform:
a more unique identity
better discoverability
stronger branding opportunities
while still maintaining the original vision and pronunciation.

The app is already live
Flinck is currently available and gradually growing its user base.

We just hit 50+ users since our launch at 22nd of April 2026. Thanks for using Flink!

David Uchenna, has built a platform called Flink, designed to help farmers connect with buyers and sell their produce more easily.
The idea is to solve a common problem in agriculture:
Farmers produce food, but struggle to sell at the right price.
Middlemen often control the market, and farmers end up earning less than they should.
At the same time, buyers don’t always have a direct way to find reliable farmers.

How Flink works:
Flink is built as an agricultural social marketplace, combining multiple features into one platform:
Farmers can create accounts and connect with others
They can post updates and share farming insights
Farm produce can be listed for buyers to discover
Buyers can reach out directly to sellers
It’s like combining social media + marketplace, but focused on agriculture.

What makes it different:
Unlike platforms like Jiji, which are general marketplaces, Flink is built specifically for agriculture.
The goal is not just buying and selling, but also:
helping farmers connect
improving access to information
creating more transparency in pricing

Availability:
The app is already live and available for use.

I’ve been thinking about this more…

One major issue is farmers don’t even know the real market price of their goods before selling.

That’s why middlemen always win.

Do you think farmers in Nigeria would actually trust a platform like this?

For years, many farmers in Nigeria have faced the same problem:

They produce food… but struggle to sell at the right price.

Middlemen often control pricing, and farmers end up earning less than they should.

Farmers are also scattered across different platforms, with no central place to connect, share insights, or grow together.

At the same time, buyers struggle to find reliable farmers directly.



This is the problem a young Nigerian engineer is trying to solve.

At just 16, David Uchenna is building Flink, an Agri Social Marketplace.

Instead of just another farming app, Flink combines:

- Social interaction (farmers sharing updates, experiences, and insights)
- Marketplace (buying and selling farm produce directly)
- AI tools (crop recommendations, farming assistant, and decision support)
- Logistics support (helping connect farmers to delivery options)

Think of it like social media + marketplace + smart farming tools, all in one platform built specifically for agriculture.



Why this matters:

- Farmers can sell directly to buyers
- Buyers can find trusted sources easily
- Less dependence on middlemen
- More transparency in pricing
- Access to AI trained for agricultural decisions
- Easier movement of goods through logistics support



Agriculture is one of Africa’s biggest industries, yet it’s still largely offline and disconnected.

Platforms like this could change how farmers operate entirely, from how they learn, to how they sell.



Flink is still in its early stage and opening access gradually.
