You will get a Production Readiness Audit of your AI-built apps eg. Lovable, Base44,...

Project details
Your app works — but is it safe to succeed? Independent research found that 45% of AI-generated code fails basic security tests, and thousands of live vibe-coded apps expose secrets and personal data without their owners knowing.
I audit AI-built applications before that becomes your story. You get a written, prioritized report covering:
SECURITY — authentication and authorization logic, Supabase Row Level Security, exposed secrets and API keys, endpoint access control, payment integration safety.
ARCHITECTURE & SCALING — what breaks at 10x your current usage, database and backend design, what you actually own if you leave the platform tomorrow.
COST — your platform's credit/usage billing trajectory and where it will surprise you.
ROADMAP — every finding ranked by risk and effort, so you know exactly what to fix first, whether you fix it with me or with anyone else.
About me: Expert-Vetted (top 1% of Upwork), 100% Job Success, 30 years in fintech and enterprise architecture, founder of a production agentic-AI platform.
No judgment on how the app was built. Just an honest, senior, independent answer to the question: is this ready for real users, real money, and real growth?

Fractional CTO & Project Manager
I worked with Sina for almost a year on a project that I was deeply passionate about. He’s a lovely human, full of enthusiasm and spirit and he very quickly became a fellow traveler on the journey of creation.
He works very fast, and was able to deliver original applications that worked well and had minimal bugs and complications. He also was able to conceptualize and manage complex tasks and see his way through them. He has positioned himself at the forefront of the AI revolution so he has up to the minute ability to pivot to newly available technology.
Most impressively, I saw Sina as very humble and open and willing to quickly acknowledge areas he could improve. One such area was in ensuring we aligned in depth on vision/work plan/focus before he went and built things. I found it a great asset though that he sparks on many of his own ideas.
I highly recommend working with Sina, he will brighten your day and help you realize your dream.

Build MVP for Coffee Gifting App (Firebase, Static HTML, Google Sheets)
I came to Sina with an idea for an MVP for my online startup — something that involved pulling together multiple external tools. He understood the concept straight away and quickly found ways to simplify things. Instead of just stitching tools together, he figured out how to integrate more of them into the script or swap them out for cleaner solutions that worked better overall.
Communication was great from start to finish. I always knew where things stood, what was coming next, and how he was planning to solve any bumps along the way. Sina was quick, reliable, and easy to work with — and he delivered a fully working MVP in a short amount of time.
Really happy with the outcome and looking forward to working with him again soon.

Great work! Sina completed everything super-fast and the result was of a very good quality.
Will definitely look to hire Sina again for the future jobs.

Advisory on enterprise-grade server infrastructure
He was seriously one of the top if hes not the best freelancer I’ve work with, in other websites i hire +100 freelancers, sina is another level, understand our entire project with its own complexity in 7 minutes, usually it takes 30-90 minutes to fully understand it, I even talk about him in our company, what a solution architect, literally the GOAT ! I’m writing this without AI, from my heart, he doesnt need a review anyway, he is more than that but I just wanna people know how insane this man is, thanks Sina, you have a real impact on our entire company:

Job Success
Lahti, Finland - 1:28 am local time
I make AI-era software safe to succeed: independent audits, production hardening,
and fractional CTO leadership, backed by 30 years in fintech, payments
infrastructure, and enterprise architecture.
💎 Expert-Vetted (top 1% on Upwork) · 100% Job Success · $500K+ earned · 3,700+ hours
A recent client, after a one-hour advisory session:
"He understood our entire project with its own complexity in 7 minutes — usually it
takes hours minutes to fully understand it... what a solution architect. Thanks Sina,
you have a real impact on our entire company."
That speed of diagnosis is what you're buying. Here's how I apply it:
╔════════════════════════════════════════════════╗
▫️🕵️ PRODUCTION READINESS AUDIT & HARDENING — for AI-built apps
╚════════════════════════════════════════════════╝
You built with Lovable, Bolt.new, Replit, Base44, v0, Cursor, or Claude Code. The
platform got you 70% there. The last 30% — security, real backends, payments,
scaling — is where I work.
Fixed-price Production Readiness Audit (72h): security review (authentication,
Supabase RLS, exposed secrets, API access control), architecture and scaling
assessment, platform cost/lock-in analysis, and a prioritized roadmap you can act
on with me or with anyone.
Hardening Sprint: I implement what matters — proper backend, payments done
correctly, CI/CD, monitoring — and hand over clean, documented code you own.
From an MVP client: "Instead of just stitching tools together, he figured out how to
integrate more of them into the script or swap them out for cleaner solutions that
worked better overall... he delivered a fully working MVP in a short amount of time."
╔════════════════════════════════════════════════╗
▫️🧑🏻💻 FRACTIONAL CTO & TECHNICAL DUE DILIGENCE
╚════════════════════════════════════════════════╝
Senior technical ownership without the full-time price tag. On Upwork alone I've run
fractional CTO, head-of-product, and coaching engagements of 590 to 1,078 hours
for US and EU companies — architecture, team building, vendor decisions, and the
accountability layer no AI tool provides.
Independent Technical Due Diligence for investors and acquirers: an unbiased,
written assessment of a codebase, team, and architecture — increasingly critical
when the product you're buying was substantially AI-generated.
From a fintech founder: "His product sense is top-tier, and his technical knowledge
is deep. Sina was able to hire a small team and develop a strong sense of culture
and accountability for his reports."
From a year-long engagement: "He has positioned himself at the forefront of the AI
revolution so he has up to the minute ability to pivot to newly available technology."
╔════════════════════════════════════════════════╗
▫️🤖 3. AI AGENT SYSTEMS, GOVERNANCE & EU COMPLIANCE
╚════════════════════════════════════════════════╝
I founded and architected työ — a production agentic AI platform for customer
messaging: AI drafts, humans sign off, EU data residency, event-sourced kernel,
Temporal orchestration. I don't theorize about agents in production; I operate one.
Architecture and review of agentic systems with human-in-the-loop accountability
AI governance and EU compliance readiness for teams shipping AI features
Anthropic-certified, June 2026: Building with the Claude API · Model Context
Protocol (MCP): Advanced Topics
╔════════════════════════════════════════════════╗
▫️💳 FINTECH & PAYMENTS DEPTH
╚════════════════════════════════════════════════╝
Solutions architect for a consumer credit card platform; payment gateway and PSP
advisory (Stripe and beyond). "I will certainly reach out to Sina next time we have an
issue around financial platforms like Stripe, Zai and the others."
If your AI-built app takes money, this is where mistakes are most expensive — and
where I've spent two decades.
╔════════════════════════════════════════════════╗
▫️🛠️ HOW I WORK
╚════════════════════════════════════════════════╝
I use Claude Code and Cursor daily, and I use them well — but that's not what you
pay for. You pay for what the tools can't do: knowing what to build, verifying what
got built, and being accountable when it's your revenue on the line.
Clients tag me most often as Clear Communicator, Collaborative, and Committed to
Quality. I scope honestly, show a visible win early, and tell you plainly what your
project needs — and what it doesn't.
Working languages: English, Persian (native/bilingual); Romanian (conversational);
Finnish (basic). Based in Finland (EET), comfortable with US and EU hours.
Start small: book a paid consultation or send a message describing where you're
stuck. I'll tell you honestly what it will take to ship — usually within hours.
