Expected duration: less than 1 week We're DepositScout, a UK/EU savings comparison platform that helps users find the best interest rates. We’ve built a solid backend system, but we’re now looking for an experienced developer to optimise our email alert system and make it smarter and more reliable.
The project involves enhancing our existing infrastructure, which is built with Node.js (Express) using TypeScript and PostgreSQL (via Drizzle ORM). We’re currently connected to Google Sheets for live savings data (tracking 50+ products), and we use Brevo to send email alerts to users. We have basic user preferences and 5 types of alert emails set up, but some of them are only partially functional.
What we now need is a developer who can improve the way we match user preferences to rate changes, upgrade the database structure to better store these preferences, introduce background jobs to automate data monitoring and email triggers, and clean up our email templates to improve readability and engagement.
We’re specifically looking for someone with:
Strong experience with Node.js and TypeScript
Solid PostgreSQL knowledge, including schema design
Experience with the Google Sheets API and background task management
Familiarity with email systems like Brevo (or similar)
An eye for performance and reliability
Deliverables will include a smarter alert system that can handle thousands of users, an optimised database schema, more efficient use of the Google Sheets API (e.g. fewer calls), automated background tasks for monitoring and alerts, improved email templates, and well-commented code with basic documentation.
The current stack includes Node.js (TypeScript), PostgreSQL with Drizzle, Google Sheets + Brevo for email, and the project is hosted on Replit. The data we're dealing with updates in near real-time (rates change every 10 minutes), so performance and efficiency matter.
We’re working within a budget of £200–£400 depending on experience and quality of work. If you have previous experience building systems like this — especially within FinTech, or any project involving alerts, emails, or comparison tools — we’d love to hear from you.
