Full Stack AI Engineer
Tired of developers who just write code but don't move the needle? Need AI systems that actually save time, cut costs, and grow revenue and not another chatbot demo?
I'm a Full-Stack AI Engineer & A...
About this Gig
Is a hidden bug or a sudden app crash costing you users, revenue, and sleep?
I specialize in rescuing, upgrading, and optimizing full-stack applications built on Next.js, React, Node.js/Python, and Supabase.
I Fix My Clients Issues:
Random App Crashes
- I set up advanced client-side tracing (W3C Trace Context) across JS, Python, Swift, and Flutter to see exactly where your app is breaking from user click to database log.
Slow Load Times & AI Timeouts
- I optimize heavy queries using modern Supabase Postgres Changesintroducing column selection so your server isn't pulling full, bloated rows.
Security & Auth Vulnerabilities
- I audit leaky API keys, configure secure Row-Level Security (RLS), and set up tightly scoped, org-specific personal access tokens so your system is locked down.
Outdated Codebases
- Upgrading legacy packages, fixing broken REST APIs, and patching failing Edge Functions to support higher traffic limits.
Deep Audit
- I review your app architecture and error logs.Isolate: Find the exact script, database query, or security flaw causing the breakdown.
Fix & Optimize
- Deploy clean code and configure monitoring so it never happens again.

FAQ
What information do you need to start debugging my app right away?
I need a clear description of the issue, steps to reproduce the bug, screenshots or video recordings of the crash, and access to your error logs or repository (GitHub/GitLab).
Can you fix an app crash without giving you full access to my database?
Yes. We can start with a code audit or look at obfuscated error logs. However, for deep database bugs or Supabase RLS troubleshooting, temporary environment access is usually required.
How do you trace random crashes that don't happen all the time?
I implement client-side tracing using W3C Trace Context. This links your frontend actions directly to your Supabase logs with a unique trace_id, capturing intermittent crashes in real time.
My app is loading incredibly slow. Can you fix this without rewriting everything?
Absolutely. Most slowdowns are caused by heavy database payloads. I optimize this using Supabase Postgres Changes to fetch only required columns instead of pulling full, bloated rows.
We had an API key leak. Can you secure our application?
Yes. I will instantly revoke compromised keys, set up tightly scoped Personal Access Tokens restricted to specific permissions, and harden your Supabase Row-Level Security (RLS).
What specific tech stacks do you specialize in fixing?
I specialize in Next.js, React, Node.js, Python, and Supabase ecosystems. I also debug client-side applications built with Swift, Flutter, and JavaScript.
Will fixing one bug break other parts of my application?
No. I run a full impact analysis during the code audit stage. I test fixes locally or in a staging environment before deploying them to your live production site.
Can you fix failing or timing-out AI features and LLM integrations?
Yes. I debug failing edge functions, optimize slow RAG pipelines, and configure reliable stream handling for OpenAI, Anthropic, or custom Claude MCP servers.
Do you offer emergency/express delivery if my app is completely down?
es. If your platform is bleeding revenue, message me directly before ordering. We can arrange an expedited custom order to get an engineer on it immediately.
