You will get a senior AI-readiness audit of your Node, Rails, or Angular SaaS
Top Rated
Project details
I help funded SaaS founders and CTOs add AI features to existing Node, NestJS, Ruby on Rails, or Angular applications, without breaking what already works.
This is a fixed-price, 1-week audit. You give me access to your codebase (read-only is fine); I give you a written report on exactly how to add AI safely, cost-effectively, and in the right sequence.
WHAT YOU GET
A 6–10 page audit report covering:
→ Stack assessment + AI-readiness score (14-point checklist)
→ Recommended LLM integration points ranked by ROI vs. effort
→ Infrastructure changes needed (vector DB, queues, observability, rate limiting)
→ Realistic LLM cost projections at 1×, 10×, and 100× load
→ Recommended build sequence with rough timelines
→ Risk register
Plus a 30-minute Loom walkthrough and a live 30-minute Q&A call on delivery day.
WHY ME
Top Rated Plus on Upwork (top 1%) · 9 years senior full-stack · 100% Job Success across 22 jobs · $200K+ delivered. Currently shipping AI in production with Tairly (live AI SaaS) and a Claude-powered ticket triage system handling 1,000+ tickets/month.
If you're not sure your stack is ready for AI — or which feature to ship first — this audit will tell you.

Senior Fullstack Developer
Fahad worked with us for four years as a Senior Full-stack Engineer, and I cannot recommend him highly enough. He consistently delivered high-quality, production-ready work across our entire stack i.e Ruby, Node.js, Angular, MongoDB, and AWS with minimal oversight and excellent communication throughout.
What impressed us most was his ability to own complex features end-to-end, from technical design through deployment, always on time and with thorough attention to detail. He is also one of the most AI-forward engineers I've worked with, he actively leverages modern AI development tools to deliver faster and at a higher standard.
Communication was exceptional. Working remotely across time zones was never an issue, he was always responsive, clear, and proactive. We would absolutely work with Fahad again and recommend him without hesitation to anyone looking for a senior full-stack engineer who truly delivers.

Build secure API proxy for AI dream decoder — simple Node.js job
Fahad was a pleasure to work with from start to finish. He built my Dream Decoder app with skill, patience and professionalism. The project evolved along the way as I refined my vision and he handled every change with flexibility and a solutions focused approach. He communicated clearly, responded quickly and delivered a working app I am proud to launch. I would highly recommend Fahad for any web development project and look forward to working with him again in the future.

WHAT I DO
I am an AI-native senior engineer specializing in three high-value engagements:
→ AI integration into existing SaaS — RAG, LLM workflows, Claude/OpenAI APIs in production. Recently built a NestJS + Claude support automation handling 500–1,000 tickets/month for a US e-commerce client (60% manual work eliminated).
→ Production MVPs in 2–5 weeks — currently building Tairly, a live AI resume-tailoring SaaS on Angular 19 + NestJS + PostgreSQL + Redis/Bull + OpenAI/Anthropic.
→ Senior remote engineering for European insurtech — 4+ years at Finlex GmbH (Frankfurt). Architected micro-frontends, shipped DDD refactors, and ran high-risk data migrations.

WHAT I'M *NOT* RIGHT FOR
I am not the right fit for: bug-fix gigs under $100, WordPress/template work, ultra-rush fire-fighting (under 48 hours' notice), or projects without a clear technical owner on the client side. If that's the work, there are great freelancers for it, and I am just not one.

Available for 1–2 new clients per quarter.

Kickoff & repo access (Day 1)
30-minute kickoff call. We confirm scope, you provide read-only repo access (or screenshare slot if NDA required), and I confirm the delivery date for Friday of the same week. NDA signed first if your team requires one.
Deep stack assessment (Days 2-3)
I review your codebase end-to-end: backend architecture, data layer, auth, queueing, observability, deployment, existing API surface. Each item is scored against the 14-point AI-readiness checklist.
