Explore How we build Technology for FirstResume.ai

Ever wondered how a tool like FirstResume.ai was built? How AI can be your career companion?

We’ll walk you through the technologies, frameworks, and decisions that powered this AI-driven job seeker platform.

First Things First: We Built It from scratch.

This wasn’t some borrowed template.

We at Blinker developed FirstResume.ai as a full-stack solution, tailor-made for real-world hiring challenges—no shortcuts, no compromises.

Let’s dive into the tech wizardry that powers this assistant.

The Stack Behind the Magic: Full-Stack Tech that Scales

Blinker’s product development approach is not about stitching together third-party plugins. It is all about building a robust, full-stack solution tailored to real-world challenges.

Blinker aligned with this idea to design and build FirstResume.ai using full-stack technologies and modern tools that not only perform but also evolve with users’ needs.

Let’s break down the tech wizardry that powers this AI-backed job-seeking assistant.

Frontend Technologies

Next.js – Lightning Fast Web Performance

Blinker picked Next.js, a React-based framework, for its unmatched performance and SEO friendliness. With built-in server-side rendering and smart routing, FirstResume.ai ensures that every user gets a fast, snappy experience—whether they’re generating resumes or prepping for interviews.

Why it matters:

• Faster page loads
• Better SEO indexing
• Great for dynamic, data-rich UIs

TypeScript – Strong Typing for Reliable Code

Frontend and backend both run on TypeScript, a superset of JavaScript with typing. This provides structure, reduces bugs, and improves team collaboration. Especially when dealing with form validation, API integration, and dynamic resume content, TypeScript keeps the system tight and predictable.

ShadCN – Clean, Customizable UI Components

Design matters in resumes. Blinker adopted ShadCN, a headless UI library, to create beautiful, modular, and customizable user interfaces. Unlike bloated UI kits, ShadCN offers total control over design without sacrificing performance.

Tailwind CSS—Rapid, Responsive UI Development

With Tailwind CSS, the development team built fully responsive interfaces in record time. It’s a utility-first CSS framework that lets you design directly within the HTML, cutting down on redundant code and making real-time prototyping a breeze.

Backend Technologies

1. Express.js – Flexible and Scalable API Backbone

Blinker used Express.js, the most reliable Node.js web framework. With Express, the backend team has granular control over API routes, authentication, user data, and all backend services. It also makes future integrations (like CRMs or job boards) seamless.

2. TypeScript on the Backend Too

Again, TypeScript brings consistency, predictability, and fewer runtime bugs. When building complex business logic like resume scoring, AI content generation, and user behavior tracking, type safety is non-negotiable.

3. Puppeteer – PDF That Looks Exactly Right

Here’s a cool bit: users want resumes that look exactly the same on paper as they do on screen. So Blinker used Puppeteer, a Node.js library that uses a headless browser to render HTML to PDF. This ensures: WYSIWYG (What You See Is What You Get) resumes

No broken styles or formatting issues

Print-ready documents with zero compromise

Database and Data Handling

MongoDB – Flexible, Scalable Storage

MongoDB was chosen for its schema-less flexibility—perfect for evolving data structures like resume fields, cover letters, mock interview attempts, etc.

Deployment Strategy

1. AWS Amplify – Frontend Deployment Made Simple

Blinker deploys its Next.js frontend on AWS Amplify, which is perfect for React-based apps. Amplify handles builds, SSL, version control, and continuous deployment—keeping the infrastructure light and agile.

2. AWS EC2 – Powerful and Configurable Backend Hosting

For the backend (Express.js), AWS EC2 offers:

• Custom server setups
• Better security controls
• Scalable performance

Whether it’s 100 users or 100,000, EC2 handles the load.

From Blank Page to Job-Ready Resume: How FirstResume Uses OpenAI Smartly

Firstresume.ai isn’t just a tech stack. It’s smart—really smart—thanks to deep OpenAI integration.

Blinker didn’t just plug in OpenAI and hope for the best. The team:

Engineered custom GPT prompts for job-specific resume and cover letter generation

Tuned outputs to mimic industry-specific language and tone

Ensured non-repetitive, human-sounding results

Whether you’re applying for a data analyst role or a creative design position, FirstResume adapts the content like a human mentor would.
