You will get a senior AI/LLM production audit with prioritized fixes
Project details
I'm a Principal Engineer with 12+ years building AI-powered SaaS at scale. 3 years at Apple (London and California), then founded Setzzy — an AI and real-time SaaS that I scaled to $1.45M in funding across 20+ countries and exited in Q1 2026.
This audit is for teams who have shipped an AI or LLM feature and want a senior set of eyes before scaling, raising, or rolling it out to more users. I look at 8 production-readiness dimensions: prompts, eval coverage, hallucination risk, latency budget, cost per call, observability, security, and model routing.
What you get: a written scorecard, a prioritized fix list with effort estimates, quick wins separated from larger refactors, and a 60-min review call to walk through findings.
What sets this apart: I have shipped, scaled, and exited a production AI SaaS using LangChain, LangGraph, RAG over pgvector, and OpenAI plus Anthropic Claude with model routing. The audit is grounded in what actually breaks in production, not theory.
Best fit: founders, CTOs, and product managers who shipped an AI feature in the last 6 months and want it production-hardened.

What I build
— AI and LLM Systems
Production RAG pipelines with pgvector, Pinecone, and custom re-rankers. Multi-agent workflows with LangChain, LangGraph, AutoGen, CrewAI. OpenAI, Anthropic Claude, Google Gemini, and open-source LLMs. Voice AI pipelines using Whisper, OpenAI Realtime, and ElevenLabs. Agent evaluation, prompt engineering, model routing, cost optimization, and production observability.
— Full-Stack Web
Next js (App Router), React, TypeScript, Tailwind, shadcn ui, tRPC. Node js, Python, FastAPI, NestJS. REST, GraphQL, gRPC. PostgreSQL with partitioning and replication, Redis, MongoDB, pgvector. Multi-tenant SaaS, Stripe Connect, and full internationalization.
— Mobile
Native iOS using Swift, SwiftUI, UIKit, Combine, and Core Data, plus React Native for cross-platform delivery.
— Real-Time and Voice
WebRTC, Socket io, sub-second turn-taking across cross-border sessions. Kafka, Redis Pub/Sub, SQS, BullMQ, and Temporal for async job orchestration.
— Cloud and DevOps
AWS (ECS, RDS, Lambda, S3, Bedrock), Kubernetes, Docker, Terraform, and GitHub Actions. Sustained 99.9% uptime under thousands of concurrent users at Setzzy.
Selected impact

How I work
Direct, async, ownership-first. I treat your codebase like my own. Comfortable with ambiguous briefs. I translate business goals into shipped product, engineering standards, and reliable delivery cycles. Available immediately, 30+ hours per week, remote globally.
Let's talk if you need
— An AI feature or product built end-to-end, not just a prototype
— A senior engineer who can architect and ship, not just write code
— A technical advisor or fractional CTO for early-stage product decisions
— A founder-engineer who has been on your side of the table
Quick to respond. Happy to hop on a short call to scope things out.
Steps for completing your project
After purchasing the project, send requirements so Yunus can start the project.
Delivery time starts when Yunus receives requirements from you.
Yunus works on your project following the steps below.
Revisions may occur after the delivery date.
Kickoff and pipeline walkthrough
30-minute call to walk through your current LLM pipeline, eval setup, observability, and known pain points. I take notes and share an initial scope confirmation within 24 hours.
Production-readiness audit
I audit 8 dimensions: prompts, eval coverage, hallucination risk, latency budget, cost per call, observability, security, and model routing. Findings tracked in a shared doc as I go.
