Meet Sieve. ☀️
The moment an inquiry lands, Sieve reads it, scores it against your criteria, and hands you a call-ready brief. What they want. Whether they can afford it.
Sieve reads every inquiry the moment it lands, scores the fit, and hands you a call-ready brief — so you spend your time on the people worth talking to.
Service businesses sell their expertise, but the first hour of every inquiry is spent on admin — reading, sorting, replying, guessing. Sieve takes that hour back. Inquiries land in one place, get scored against the rubric you set, and come back as a call-ready brief: what they want, whether they can afford it, how urgent it is, and what to ask next. You see the whole pipeline at a glance, work the ones that fit, and let the rest go politely. It runs the same way at 11pm as it does on a Tuesday morning, and it never forgets to follow up.
The problem
What: A good lead and a bad one look identical in your inbox. Sorting them is unpaid work, and it happens exactly when you're busiest — so replies get slower, good leads go cold, and you end up on calls that were never going to close.
Who: Small service businesses — studios, consultancies, agencies, contractors — usually 2–20 people, where the owner is still the one doing the selling.
Why it matters: Speed and judgment decide who wins the work. Sieve gives every inquiry the same careful first pass, in minutes, so the only thing you spend your time on is the conversation that's worth having.
Enjoyed working on this project!😊 Thank you Base44 💙

Ripcord. One pull for the day you can't go in.
You wake up ill. Client meetings, a deadline, people waiting on you. The worst part isn't the fever. It's the admin.
So I built a cord. Drag it down, say how long you're out, and Ripcord does the rest:
Moves your real Google Calendar meetings to your next free slots
Shifts your deadlines by the days you lose
Writes one short note per client in your voice, sent from your own Gmail
Plans your first morning back
Keeps a receipt for every change. Hold to undo any of it.
Can't face another app? There's an MCP server too. Tell Claude "I've got the flu, clear my week" and it pulls the cord for you.
Built entirely on Base44: entities with owner-only security, 27 backend functions, Google Calendar and Gmail connectors so each user connects their own account, InvokeLLM for the notes, and an hourly workflow for the heads-up and welcome-back emails. I tested it on my own calendar: the meetings moved, the notes landed, and undo put everything back.
The design is a "Signal Room": one glowing red cord on an LED wall. It works on your phone, one-handed, from bed.

Great work as always, AJ 😊
Built SpeedPulse AI — an automated website performance teardown and local client acquisition engine.
Most local businesses lose over 35% of their mobile conversions due to slow load times and missing Google SEO schema. Auditing each client manually took hours, so I automated the entire process on Base44:
⚡ Real-time Core Web Vitals, Local SEO & UX friction score dials
🔄 Dynamic Before/After sprint projections (gliding scores from 45 to 91+)
📄 Automated Executive PDF brief generation
🤖 Built-in Agency CRM that captures incoming leads, tracks stages, and auto-drafts client proposals with one-click copy

Every morning, before the sun is fully up, Nigeria's motor parks are already moving.
At Jibowu, Ojota, Utako, Mile 1 and hundreds of parks across the country, buses are loading, and tucked between the passengers' bags are parcels. A mother sending foodstuff to her son at university in Sokoto. A trader in Onitsha restocking a shop in Kano. Documents, phones, fabric, medicine, gifts. All of it riding to towns and villages that most courier companies don't even list on their website.
This is Africa's real delivery network. It is fast, it is everywhere, and it runs on trust. But it's also invisible.
You hand your parcel to a driver you just met. You collect a number scribbled on paper. Then you wait, and you call, and you call again. Is it on the road? Has it arrived? Did it get lost at the next park? There's no tracking, no receipt and no record. When something goes wrong, there's no one to turn to.
The drivers aren't the problem. They are the heroes of this story. They drive these routes every single day. What's missing is the layer that connects them to the people who need them.
So for Base44's #GiveItAGlow challenge x Contra, I gave that network a glow-up and called it Waybill.
Waybill puts your parcel on a bus that's already going. You search your route and see the drivers who are loading or about to depart, with their price, vehicle and rating. You pay safely in the app, and the driver's number unlocks. At the park, the parcel is photographed and weighed. Then you and your receiver watch it move, town by town, until it's delivered.
Then I made sure nobody has to chase anybody. Ten automations run quietly in the background:
• You book, and an animated email confirms it's waiting for the driver to accept
• Drivers on that exact route are alerted the moment a paid parcel appears
• The receiver gets a tracking link at every stage, with no app or account needed
• Unpaid bookings get a reminder, then cancel themselves
• A parcel that goes quiet for 6 hours nudges its driver. After 12, the team is alerted
• Drivers who stop updating drop out of search, so you only see who is really moving
• Every Monday, drivers get their earnings. Every morning, the team gets an ops digest
The design comes straight from the park: headlines set like painted route boards, danfo yellow and road-sign green, and a waybill slip, the same paper ticket every park hands you, that fills itself in and gets stamped CONFIRMED.
For a driver, this means extra income from seats and space that already exist. For a sender, it means peace of mind. For a small business, it means reaching customers in towns that were too far before. Multiply that across every park in Nigeria, then across Africa, and you start to see how big this can be.
The infrastructure is already on the road. It just needed a glow-up. 🇳🇬
Built end to end with @Base44: the app, database, workflows and emails. Made in Sokoto by Low Code Africa.

This is a brilliant solution to a real African problem! 🔥👏 Turning our existing transport network into a reliable, trackable delivery system is a smart move. Waybill is more than an app; it’s a bridge between trust, technology, and everyday logistics. 🇳🇬🚀
