WHY FOUNDERS TRUST US

How we help vibe coders & teams ship with confidence.

Building with AI tools is fast. Launching safely requires senior engineering judgment. We bridge the gap between rapid prototype generation and production-grade security.

VALUE 01

From AI Prototype to Enterprise Trust

Closing the gap between fast generation and real user security

Tools like Lovable, Bolt, and Cursor make building apps effortless. But they often skip session validation, over-fetch entire database tables to the browser, and leave API keys exposed. We turn fragile code into battle-hardened SaaS.

  • Eliminate hidden data leaks in client-side bundles
  • Ensure private user records stay strictly private
  • Shield your database from unauthenticated scrapers and bots
VALUE 02

Senior Developer PRs — Not Generic PDFs

Actual working code delivered straight to your GitHub repo

Traditional security agencies hand you a 60-page PDF report with complex jargon and leave you to fix it. We don't. Our senior TypeScript engineers write, test, and submit clean, idiomatic Git pull requests directly to your repository.

  • Drop-in clean fixes with zero disruption to your visual UI
  • Detailed pull request documentation explaining every fix
  • Full regression testing before any code gets merged
VALUE 03

Zero-Downtime Infrastructure Abuse Guards

Protect your wallet from unexpected API bill spikes

An un-rate-limited OpenAI endpoint or unprotected contact form can cost thousands of dollars in minutes if targeted by bots. We install privacy-preserving HMAC rate limiting and honeypot fields that stop attacks before they execute.

  • Expiring HMAC identifiers — no raw IP address tracking required
  • Automated bot honeypots & disposable email domain filtering
  • Strict Content Security Policy (CSP) & HSTS header enforcement
TECHNOLOGY EXCELLENCE

Technologies we audit, optimize & build with.

We work natively across modern TypeScript, Next.js, and serverless database stacks. Whether your app was generated in Lovable or built from scratch in React 19, we know its internals inside out.

SOLUTIONS & DELIVERABLES

Targeted engineering solutions for every layer of your stack.

We don't just point out flaws — we write exact code fixes, test them in isolated staging builds, and submit ready-to-merge pull requests.

CRITICAL DEFENSEAuthentication & Authorization

Authorization & Server Action Hardening

Prevent unauthorized access to user accounts, tenant data, and admin actions.

We inspect every route, Server Action, and Route Handler in your application. AI builders frequently omit server-side session validation, trusting client claims. We enforce strict server-side authorization guards on every endpoint.

Impact: Stops vertical and horizontal privilege escalation vulnerabilities completely.
KEY DELIVERABLES & CHECKS:
  • Line-by-line audit of Server Actions, middleware, & API routes
  • Implementation of centralized requireOwner() & session guard helpers
  • Role-Based Access Control (RBAC) validation across tenant boundaries
  • Database Row-Level Security (RLS) policy inspection and fixes
app/actions/user-data.tsBEFORE vs AFTER FIX
❌ Vulnerable AI Code
// Vulnerable: trusts client ID directly export async function updateProfile(userId: string, data: Profile) { return db.update(users).set(data).where(eq(users.id, userId)); }
✅ Remediated TypeScript Fix
// Hardened: strict session auth & ownership verification export async function updateProfile(data: Profile) { const session = await requireOwner(); return db.update(users).set(data).where(eq(users.id, session.user.id)); }
PRIVACY FIRSTData Privacy & Payload Minimization

PII & Secret Leak Redaction

Stop over-fetching database records and leaking API secrets to frontend bundles.

When AI components query a database, they often select entire rows (`SELECT *`), sending user passwords, password hashes, internal tokens, and phone numbers straight to the browser console. We enforce minimal DTOs.

Impact: Prevents sensitive customer data and server API keys from ever touching the browser.
KEY DELIVERABLES & CHECKS:
  • Minimal Data Transfer Object (DTO) schema pattern implementation
  • Client-side JS bundle audit for leaked `.env` keys and private secrets
  • Explicit SQL field selection (returning only public fields)
  • Redaction of PII in server-side logs and error boundary handlers
server/db/queries.tsBEFORE vs AFTER FIX
❌ Vulnerable AI Code
// Over-fetching: leaks hash, resetTokens to client export async function getUser(id: string) { return await db.query.users.findFirst({ where: eq(users.id, id) }); }
✅ Remediated TypeScript Fix
// Minimal DTO: returns only necessary display fields export async function getUser(id: string) { return await db.select({ id: users.id, name: users.name, avatarUrl: users.avatarUrl }).from(users).where(eq(users.id, id)); }
COST SHIELDInfrastructure & Cost Protection

Abuse Protection & Rate Limiting

Keep your LLM & serverless infrastructure safe from costly bot attacks.

Unprotected public forms, AI generation endpoints, and search routes can be spammed by scrapers, causing massive API bills or database lockups. We implement privacy-preserving Upstash Redis rate limits.

Impact: Protects your server resources and prevents unexpected cloud & API bills.
KEY DELIVERABLES & CHECKS:
  • Privacy-preserving HMAC-hashed sliding-window rate limiters
  • Automated bot honeypots for public contact and intake forms
  • Disposable email domain blocking to prevent spam signups
  • Production Security Headers (CSP, X-Frame-Options, HSTS)
server/rate-limit.tsBEFORE vs AFTER FIX
❌ Vulnerable AI Code
// Vulnerable: no rate limiting on costly endpoint export async function POST(req: Request) { return processAIRequest(await req.json()); }
✅ Remediated TypeScript Fix
// Protected: HMAC hashed rate limiting via Upstash export async function POST(req: Request) { const token = await generateHMACIdentifier(req); const { success } = await rateLimit.limit(token); if (!success) return new Response("Too Many Requests", { status: 429 }); return processAIRequest(await req.json()); }
