A digital-certificate workflow built into a product.

Scholarcert brings certificate creation, bulk generation and public verification into one application. We built the product and its integration capabilities so certificate workflows can connect with other systems.

01The challenge

Issuing, delivering and checking certificates in one place.

Issuing personalized certificates can involve preparing recipient data, generating files and managing delivery. Scholarcert brings those steps into a shared workflow and gives each issued certificate a public verification route.

A typical manual workflow
  • Prepare recipient lists and generate files in separate tools
  • Send certificates one by one, or in ad-hoc batches
  • No shared record of what was issued to whom
  • No public page a recipient can use to show the certificate
With Scholarcert
  • Bulk-generate personalized PDF + PNG in one run
  • Deliver immediately, on a schedule, or by hand
  • Each certificate has a unique ID and a public verification page
  • An audit trail of issuance, plus an API for other systems
02What we built

Not a feature — a whole platform.

A complete, production SaaS. Organizers set up conferences and editions, add recipients by dashboard, CSV, or API — and Scholarcert generates personalized certificates with a QR code and delivers them. Bind any element to a data field like {{full_name}} and it fills from the recipient list. Every certificate has a unique ID and a public verification page. Built across 13 phases, live and running in production. Scholarcert is a product we built, not a paid client engagement. The same kind of application work sits in our custom software development service; for a related starting point, see client portal development.

03How it works · the certificate lifecycle

From setup to a certificate anyone can open — in five stages.

01 · SET UP

Create & add recipients

Set up a conference and edition; add recipients via dashboard, CSV import, or the API.

02 · DESIGN

Template, or AI convert

Upload an HTML template — or let Claude's vision AI turn a PDF into an editable one.

03 · GENERATE

Bulk PDF + PNG

Puppeteer creates personalized files, each with a unique ID (SC-2026-A7X3K) and QR.

04 · DELIVER

Send & track

Immediate, scheduled, or manual — emailed via Postmark with open/bounce tracking.

05 · VERIFY

Open the public page

Anyone scans the QR → a public page shows the issued certificate, with no login required.

certificates — bulk status
Scholarcert certificate list with statuses

Every certificate tracked: generated, sent, viewed, downloaded — searchable and filterable.

analytics — performance
Scholarcert analytics dashboard

A live analytics view — recipients, PDFs ready, delivery and engagement at a glance.

04What's under the hood

AI template conversion

Upload a PDF certificate and Claude's vision model turns it into an editable HTML template. No designer required.

Certificate engine

Bulk generation with retries, unique IDs, QR codes, and preview-and-approve before anything goes out.

Public verification

A no-login page per certificate, with PDF/PNG download, social sharing, and event tracking. It shows the issued record; it is not a claim that every forgery is impossible.

Full REST API + webhooks

API-key auth, rate limiting, full CRUD, and signed (HMAC) outbound webhooks for complete automation.

Roles, teams & audit

Role-based access (4 levels), team management, and a full audit log.

Billing & analytics

Credit-based billing, engagement dashboards, and per-edition stats.

05What the product includes

14+database tables with row-level security.

4access roles (RBAC).

3delivery modes — immediate, scheduled, manual.

100/minpublic REST API rate limit.
