Project details

Your AI SaaS can work today while still carrying authorization gaps, brittle model behavior, runaway token costs, or release risks that appear only under real users.

I will review a fixed code snapshot and turn the highest-risk problems into a practical, prioritized rescue plan. This is an implementation-minded audit—not a generic checklist or scanner dump.

Review areas can include:
• architecture and maintainability
• authentication, tenant isolation, and data access
• OpenAI/LLM/RAG/tool integrations, structured outputs, retries, and cost controls
• critical flows, billing, API boundaries, testing, CI, and observability

You receive:
• an executive assessment and risk-ranked findings
• evidence tied to relevant files and code paths
• tier-appropriate sample replacement snippets
• recommended tests and acceptance criteria
• a sequenced remediation roadmap

I’m a Top Rated Plus full-stack developer experienced with Next.js, TypeScript, React, Node.js, Python, PostgreSQL/Supabase, Stripe, and OpenAI.

This is a read-only audit. Production changes, penetration testing, compliance certification, and implementation are separately scoped.

Full-Stack Developer (React/Firebase) needed for MMA Gym Management PWA I hired Zack to build a complete management ecosystem (PWA) for my MMA Academy, featuring complex gamification and real-time logic. To say he exceeded expectations is an understatement.

1. Speed & Velocity: Zack operates at a High-Velocity pace. He deployed a robust, complex architecture significantly faster than any standard timeline I expected. He doesn't just code; he sprints.

2. Autonomy & Vision: What impressed me most was his ability to grasp Complex Business Logic immediately. He is completely Autonomous and required zero micromanagement. He understood the niche, anticipated problems, and even built extra features that improved the product.

Zack is a rare find who treats the project as his own. If you need a high-level developer to take full ownership and deliver fast, hire him immediately.

I help founders ship and rescue AI SaaS products - from OpenAI, Claude, and Gemini integrations and semantic search to authentication, Stripe billing, APIs, and deployment.

Bring me a Loom, rough specification, or existing repository. I’ll turn it into a scoped first milestone, surface the risky assumptions, and ship a working release.

I’m a strong fit for:
• AI/LLM features, semantic search, document workflows, and API integration
• Full-stack MVPs with authentication, subscriptions, databases, and deployment
• Existing React/Next.js, Supabase, or Firebase apps that need debugging, stabilization, and completion

Recent work:
• Rebuilt core search for a property platform using structured listing data, natural-language filters, Pinecone vector search, and LLM workflows
• Built a subscription gym PWA with Stripe billing and real-time member workflows
• Delivered clinical documentation and field-service systems with role-based permissions, document workflows, dashboards, and generated reports
• Built a custom React canvas for an interactive football playbook product with AI-assisted evaluation

I also created CodeTruss, an open-source acceptance gate for AI coding agents that checks scope drift and required verification.

When I enter an existing codebase, I reproduce the problem, trace the important user and data flows, and find the smallest safe path to a release. I won’t recommend a rewrite unless the evidence supports it. You’ll receive working previews, concise updates, explicit risks, and honest tradeoffs.

Core stack: TypeScript, React, Next.js, Node.js, Python/FastAPI, PostgreSQL, Supabase, Firebase, OpenAI, Anthropic, Gemini, Pinecone, Stripe, Playwright, Docker, and Vercel.

Send the Loom, repository, or one-paragraph description of what’s stuck. I’ll tell you what I would tackle first and what the first useful milestone should deliver.

Steps for completing your project

After purchasing the project, send requirements so Zack can start the project.

Delivery time starts when Zack receives requirements from you.

Zack works on your project following the steps below.

Revisions may occur after the delivery date.

Confirm scope and establish the audit baseline

I verify the selected repository, fixed commit, source LOC, priority flows, and available documentation. If the purchased tier does not match the supplied scope, I raise it before the review begins.

Review architecture and critical flows

I trace the selected flows across frontend, backend, data, authentication, billing, and AI integrations, focusing on evidence-backed security, reliability, maintainability, cost, and release risks.

Review the work, release payment, and leave feedback to Zack.
