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.

Quick UI enhancement + Mobile bug fix
Quickly helped to resolve a bug in the mobile version of an app built on lovable. Shashank worked hard to deliver ahead of schedule too.

Job Success
Delhi, India - 9:08 am local time
Recent work: I take apps that founders scaffolded in Replit, Lovable, Base44, or v0 and turn them into real, production-grade products — proper architecture, secure auth, Row Level Security, a live Supabase backend, and a codebase that actually scales instead of collapsing under its first 1,000 users.
And I don't just hand it back and disappear. I set clients up so they can keep building with these tools themselves — shipping features, running their own workflows, improving the product without needing me for every change.
I'm Shashank. One developer, 7+ years in coding. You talk to me, I build it, we ship. No account managers, no handoffs, no surprises.
: Lovable, Base44, Bolt, v0, Replit, Claude Code, Codex, Cursor, Supabase, React, Next.js, TypeScript, React Native, Flutter. Idea to working MVP to live product — faster than a traditional dev team, without cutting corners on structure, security, or quality.
**The Guarantee**
Free scoping call before you spend a penny. We map out what you're building — the features, the flows, the milestones. If we're not a fit, you walk away with a clearer vision anyway.
Working prototype in weeks. Real functionality, live database, not a mockup.
Unlimited revisions within scope. Detailed specs agreed upfront before I write a line of code.
Weeks from now you could have a live product taking payments instead of still interviewing developers.
**What I Build**
Web apps, SaaS platforms, marketplaces, booking systems, internal tools, dashboards, AI-powered products, MVPs, landing pages, and mobile apps for iOS and Android. Got a rough idea but no spec? That's what the scoping call is for.
**Why I'm Fast**
I'm AI-native. Lovable, Bolt, Base44, Replit, v0, Claude Code, Codex, Supabase, n8n — this is how I build every day, not occasionally. It lets me ship in weeks what takes traditional teams months. But the speed comes from knowing how to architect, prompt, debug, refactor, secure, and deploy with these tools properly. Anyone can vibe code. Not everyone can make it production-ready. I also mentor developers in this exact stack — you're hiring the source.
**Quality Included as Standard**
Clean architecture, secure auth, Supabase Row Level Security, technical SEO, responsive design, performance optimisation. Not add-ons. Just how I build.
**Other Things I'm Good At**
Got a Lovable, Bolt, or Base44 app that's 80% there but broken or not production-ready? I fix those a lot. AI builders get you moving fast, but someone still needs to close the gap.
Beyond that: Supabase architecture and RLS, Stripe and webhook integrations, Replit-to-production migrations, React and Next.js refactoring, Capacitor mobile wrapping, AI agent and automation workflows (n8n), and landing pages with full GA4/GTM tracking.
If you want to learn to run AI-assisted builds yourself, I do that too — a lot of clients come back for mentoring after we've shipped together.
I keep my project load small so every client gets my full attention. If I'm at capacity, I'll tell you straight away.
Every week you spend searching is a week your competitor is building. Hit Invite to Job and tell me what you're working on — I'll send a fixed-price proposal within 24 hours.
