Roast My PR

Diwanshu Jain

Contact Galaxy: the address book drawn as a network, with an edge wherever two people share a company or a city, and a collision-free card view on a phone where eighteen nodes would overlap.

Anirudh Chandnani

Took Challenge 2 all the way down: the flat columns dropped, a real addresses table with a cascading foreign key, and the Home, Work and Other constraint enforced by the database rather than the form.

Kewin Szlezingier

Moved image compression into the browser, so you can pick any photo you like and it is resized to the accepted limit before it ever leaves the page.

Shreya Singh

Dan Abay

One serialiser, two cards: a full vCard with the photo for download, and a 435-byte compact one for the QR, so pointing a phone at the screen drops the contact and its typed addresses into your address book.

Sanjay Noolu

vCard export with the photo and every address in it, plus one-click copy on emails and phone numbers, Google Maps links on addresses, and a clean print view.

Jarmar Ledesma

A player card for every contact, FIFA style, where the stats are how much you actually know about the person. Fill in more and the card levels up. Scan the QR on it and they are in your phone.

Pezanne Khambatta

Hao Yan

Spent the bonus hour on the two challenges instead: photo type and size validation, instant preview and removal, an initials fallback, the photo surviving a full edit, and real empty states on the address list.

Andre de la Cruz

Hid a contact inside a picture of one: the details are encoded into the low bits of a lossless PNG of pixel art, with a CRC-32 to prove it survived, and the site reads them back out again.

James Luo

Sameer Nagar

Drew an avatar instead of fetching one: every contact without a photo gets an inline SVG built from their initials and a hue seeded by their email, with no external avatar service involved.

Nitish Mane

Md Mashiur Rahman Khan

A .vcf download that survives accented and non-Latin names, plus an interface pass: list animations, loading states, a floating glass navigation bar, and all of it standing down for anyone who asks for less motion.

Juan Camilo Osorio

vCard import as well as export, and hardening on the API edges.

Vraj Patel

Roast My Contact: feed it the details and it roasts them, finding the prime run in a phone number or the digits of pi in it, and telling you who else is from the town in the address.

Abhishek Jani

An export button that only works because both challenges are done: the Challenge 1 photo goes out as an encoded PHOTO field, every Challenge 2 address as a typed ADR.

Akhilesh Rangani

A public page for any contact at a shareable link, Linktree style: avatar, job line, then one tappable row per way to reach them, with addresses opening in maps and phones dialling.

Hiro Yamada

One-click send pizza to your contact.

Tanmay Pajgade

Chetas Parekh

Dependency-free vCard export carrying the name, phone, email, company, job title and the typed Home, Work and Other addresses, wired into the existing contact model rather than beside it.

Ali Amjad and Sam Karri

Quick actions on the detail page that a screen reader can follow: email, call where there is a number to call, and copy with spoken success and failure, each with a test behind it.

Edward Chen

Retuned the reviewer instead of the app: a configuration in the repository wiki that has Qodo explain findings in plain language and crack jokes while it does it.

Kartikey Pandey

One-click sharing: a vCard built on the spot, handed to the native share sheet where there is one and downloaded where there is not, with long Unicode lines folded safely at the 75-octet limit.

Kaushik Immadisetty

Tomas Di Mauro

Patrick Mitchell

Het Hiren Sheth

Ben OConnor

Leo Wu-Hacohen

A scan-to-save QR on every detail page, encoding the contact and its typed addresses as a vCard, so a phone camera saves the person in one go.

Elijah Umana

Smart duplicate merge: it finds the likely matches, shows its evidence and its confidence, lets you pick the winning field by field, and then merges atomically without breaking the relational address model.

Praveen Bhandari

Four bugs off one review and then some: photo validation that reads the magic bytes rather than trusting the prefix, the size cap enforced before decoding so a 64 MB payload is refused in milliseconds, and the two repositories finally agreeing on the same limit.

Prabhjeev Sohi

Share a contact as a QR code.

Matthew Sebastian Solecki

Nishil Faldu

A whole new interface. Contact sharing between people on the same wifi was the plan, and it was still sitting on a worktree when the clock ran out.

David Van Gheel

Abhinav Ranish

A simulated AirDrop for contacts: you are advertised under an ID that rotates every thirty seconds, nobody is revealed until you have been within a metre and a half of each other for ninety, every field you share is opt-in, and the encounter itself is sealed server-side so a client cannot forge one.

Kenneth Ng

Bryan Samuel James

Nathan Moos

Rikin Shah

Two QR codes rather than one: save to phone puts the contact in your address book offline, and my card turns the app into a networking card carrying your LinkedIn and the event you met at.

Dylan Flud

Crypto wallets on a contact: as many Bitcoin, Ethereum, Solana, Base and Polygon addresses as you like, each tagged with its network, editable and copyable from the detail page.

Sean Tey

Rana Singh

A QR code that redraws itself as the contact changes.
