Project details
Launching a SaaS or web app and not sure it's safe? I find the problems before your users do. I'm a senior full-stack developer (5+ years) specializing in code audits of React, TypeScript, Next.js and Postgres-backed apps — including products built with AI builder tools, which often ship with hidden security gaps. On a recent audit I found an unguarded route exposing the owner's proprietary system prompt and live API billing to anyone with the URL. That's the class of issue I catch: exposed routes and API keys, broken permissions and row-level security, data leaks, unvalidated inputs, and database design that won't survive real traffic. What you get: a clear findings report with every issue ranked by severity (Critical to Low), explained in plain English, and mapped to a concrete fix — plus a prioritized roadmap so you know exactly what to do first. No jargon dumps, no vague "best practice" lectures. You'll know what's broken, how bad it is, and how to fix it. Whether you're days from launch or already live with paying users, an independent senior audit is the cheapest insurance you can buy. Your code stays confidential — NDA-friendly, read-only access only.

WHAT I BUILD
🔹 AI Agents & LLM Integration — production Claude, OpenAI (GPT), and Gemini pipelines with structured outputs, prompt engineering, RAG (pgvector, embeddings), and agent orchestration. Anthropic-certified: Claude Code in Action + MCP Advanced Topics.
🔹 Voice AI Agents — I built SweepTalk (sweeptalk.in), a multi-tenant AI voice agent SaaS: real-time calls on LiveKit, ElevenLabs, Deepgram-class STT/TTS, PSTN telephony, 273 tests in CI. Missed-call recovery, AI receptionists, outbound calling agents, appointment booking bots.
🔹 MCP Server Development — custom Model Context Protocol servers connecting Claude to your APIs, tools, and internal systems. I've shipped a production OAuth 2.0 MCP server, and I hold Anthropic's MCP certification — few freelancers do.
🔹 AI Code Rescue & Audits — inherited a codebase from Lovable, Replit, Cursor, Bolt, or another developer? I audit and productionize AI-generated code: security review, RLS policies, architecture cleanup, severity-scored reports. 2 years of Replit experience across 15+ reviewed Upwork projects; 20+ production sites shipped via Lovable.
🔹 AI Automation & Workflows — n8n, Make, Zapier (I ship a native Zapier integration my paying users run), webhook architectures, CRM integration (HubSpot, Salesforce, Pipedrive, GoHighLevel), email and outreach automation with retry + dead-letter handling.
🔹 Full-Stack SaaS Development — React, Next.js, TypeScript, Node, Python, FastAPI, PostgreSQL, Supabase (Auth, RLS, Edge Functions), Redis, Docker, AWS. Multi-tenant architecture, RBAC, payments, CI/CD.
🔹 Mobile Apps (iOS + Android) — React Native, Expo, Flutter. Solo developer of CrisisOR (clinical simulation for anesthesiologists, CME-linked) and lead developer of Ask First (AI health app, 5.0★) — both live on the App Store, plus Luzo, Joyce Meyer Ministries, and GlamourBook.
PROOF, NOT PROMISES
✅ SweepTalk — sweeptalk.in — my multi-tenant voice AI SaaS
✅ Leadscraper — my.leadscraper.de — 1,000+ paying users, AI lead-gen SaaS
✅ Altius — altius.trade — production DEX (financial-grade correctness)
✅ CrisisOR + Ask First — healthcare apps live on the App Store
HOW I WORK
I work agent-first with Claude Code daily — AI speed with engineer-grade review. Everything ships with tests, docs, and clean handoff. I flag risks before building, not after delivery. If your last developer (or AI tool) left you something half-finished, my first deliverable is a written map of what actually exists — before I change a line.
Let's talk about your project — I respond fast and I'll tell you honestly if I'm not the right fit.
