We engineer
web applications that last.
From scalable Next.js platforms and complex legacy migrations to rescuing fragile AI-generated prototypes, we turn web technology into high-performing, maintainable software.
Private keys detected in browser bundle; refactored to Next.js Server Actions.
Unprotected tables accessible via public anon key; hardened with row-level security.
Supabase auth session middleware normalized for SSR & edge cookies.
Web systems rarely fail because of a single bug.
Sometimes the code is unfinished. Sometimes the infrastructure is fragile. Sometimes the website is slow, outdated, or impossible to maintain. We help you isolate the root cause, fix the foundation, and move forward with confidence.
Your AI-generated app is stuck at 80%.
You built an MVP with Cursor, Bolt, Lovable, or Claude Code, but you hit a wall with broken OAuth cookies, client secret leaks, and database deadlock bugs.
Your website is slow and losing conversions.
Years of plugin bloat, sluggish database queries, and poor mobile scores cause high bounce rates and trigger Google search ranking penalties.
Your server, database, or domain went offline.
An expired SSL certificate, unmonitored server memory leak, DNS misconfiguration, or crashed database has taken your critical business revenue offline.
Your deployment process is fragile and manual.
Deploying code involves nervous midnight releases, unexpected downtime, manual SSH commands, and missing automated rollback safeguards.
Your product works — but only locally.
Environment drift, missing database seeds, unhandled environment variables, and Docker build failures keep your application stuck on a developer's machine.
Your existing system needs to modernize.
Your business has outgrown its legacy monolithic PHP or no-code builder and needs a modern, scalable TypeScript & Next.js architecture.
Three questions, then we take it from there
Tap what is going on, add a line of detail, and leave an email. No forms to fill out before you know whether we can help.
Your AI-built app is 80% done.
We engineer the 20% that ships.
AI coding tools like Cursor, Bolt, Lovable, Replit, and Claude Code accelerate prototypes, but generated code often contains dangerous secret exposures, fragile state loops, and missing database security. We step in, audit the codebase, eliminate vulnerabilities, and launch production-grade software.
// ✅ HARDENED PRODUCTION TYPESCRIPT (app/actions/checkout.ts)
"use server";
import { auth } from "@/lib/auth";
import { stripe } from "@/lib/stripe";
import { db } from "@/lib/db";
import { z } from "zod";
const CheckoutSchema = z.object({
planId: z.string().uuid(),
});
export async function createCheckoutSession(formData: unknown) {
const session = await auth();
if (!session?.user?.id) throw new Error("Unauthorized");
const { planId } = CheckoutSchema.parse(formData);
// ✅ Server-side execution, encrypted secrets & atomic DB record
const checkout = await stripe.checkout.sessions.create({
customer: session.user.stripeCustomerId,
line_items: [{ price: planId, quantity: 1 }],
mode: "subscription",
success_url: `${process.env.APP_URL}/dashboard?success=true`,
});
return { url: checkout.url };
}See the difference senior craftsmanship makes.
AI code generators and quick-fix agencies build fragile prototypes that break at scale. Here is how JoinAffix hardens architecture for production resilience.
Transform Fragile Vibe Prototypes into Secure, Type-Safe Systems
// ❌ Fragile Prototype (Cursor / Bolt / Lovable)
"use client";
import { createClient } from "@supabase/supabase-js";
// CRITICAL: Leaked service role bypasses all RLS!
const supabase = createClient(
process.env.NEXT_PUBLIC_SUPABASE_URL!,
process.env.SUPABASE_SERVICE_ROLE_KEY!
);
export function UpdateBilling({ orgId, planId }: any) {
useEffect(() => {
// Unauthenticated client mutation without schema validation
supabase.from("organizations")
.update({ plan: planId })
.eq("id", orgId);
}, [planId]); // Infinite trigger on re-renders
}// ✅ Production-Hardened (JoinAffix Standard)
"use server";
import { auth } from "@/lib/auth";
import { db } from "@/lib/db";
import { z } from "zod";
const BillingSchema = z.object({
orgId: z.string().uuid(),
planId: z.enum(["starter", "growth", "scale"]),
});
export async function updateBillingAction(rawInput: unknown) {
const session = await auth();
if (!session?.user?.id) throw new Error("Unauthorized");
const input = BillingSchema.parse(rawInput);
// Scoped to verified user tenancy with PostgreSQL RLS
return await db.organization.update({
where: { id: input.orgId, ownerId: session.user.id },
data: { plan: input.planId },
});
