Building Software is easy. Shipping a product isn't.

Introduction

Launching my first real project made me realize that writing code is the easy part. The real challenge starts when everything around it needs to work for real. After many experiments and late nights, I finally put my SaaS live, and I wanted to share a bit of this journey with you.

Tech Stack

I built everything using Python, FastAPI, Vite, and React. The application is hosted on AWS, leveraging RDS, CloudFront, and S3. The CI/CD pipeline is powered by GitHub Actions. Security was a top priority: firewalls, captchas, a custom authentication system, OAuth, and VPCs kept completely closed to the internet.

Infrastructure & Operations

Dealing with environments, observability, logs, metrics, and alerts quickly becomes part of the daily routine. Handling exceptions with services like Sentry reveals production errors you would never see locally. You also need to manage privacy policies, terms of service, backups, and everything that comes with running a real product.

Marketing & User Experience

Even if your product is technically solid, no one will use it until they know it exists. Building a narrative, repeating it, studying SEO, and running paid traffic all consume time and resources. A good onboarding flow and solid UX are essential to avoid confusion. Retention is another whole discipline that comes later.

Product Overview

The product I launched is an AI‑powered platform to practice interviews. Instead of static questions, users talk to customized agents. These agents are built by studying chains with LangChain and applying fine adjustments to simulate different interviewer profiles.

During the interview, the platform provides real‑time feedback on each answer. At the end, it generates a comprehensive overview with strengths, areas for improvement, and clear suggestions for next steps. Users can also create their own interview agent to train.

Invitation

I invite you to try the platform, explore the custom agents, and share any technical feedback. This was my first launch, and there is still a lot to improve. I hope the tool is useful and that my experience encourages others to put their projects out into the world.

Feel free to share your impressions—they would already help a lot.
