SSL Certificate Error or Site Not Secure Warning
Your app shows a 'Not Secure' warning in the browser, or visitors see a full-page SSL/TLS certificate error warning them the site is unsafe. This scares users away and can break functionality like payments and auth.
Common Causes
- SSL certificate not installed or expired
- Custom domain not properly configured with your hosting provider
- Mixed content — HTTPS page loading HTTP resources
- DNS records not pointing to the correct server
- Hosting provider doesn't auto-provision SSL for custom domains
How to Fix It
- Check if your hosting provider offers free SSL (most do — Vercel, Netlify, Railway auto-provision)
- Verify your DNS records are correct (A record or CNAME pointing to your host)
- If using a custom domain, check the hosting provider's domain settings for SSL status
- Look for mixed content warnings in the browser console and update HTTP URLs to HTTPS
- Wait up to 24 hours after DNS changes for SSL to provision

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.

I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

My site shows 'Not Secure'. Will this affect my business?
Yes. Browsers warn users away from non-HTTPS sites, payment providers require HTTPS, and Google penalizes non-HTTPS sites in search rankings. Fix this as soon as possible.
I added a custom domain and now SSL is broken. What happened?
Your hosting provider needs to provision an SSL certificate for your custom domain. Check their domain settings — most do this automatically but it can take a few hours.
