Machine Learning Engineer at Evren AI, Level 2 Fiverr seller, and final year CS student. I design voice and chat AI agents, multi-agent workflows, and high-performing Meta and Google ad systems for brands around the world.
Final-year BS Computer Science student (8th semester) and Machine Learning Engineer at Evren AI, where I build production RAG agents, controlled-response conversational AI, and automation pipelines for real client-facing products.
My work sits at the intersection of two disciplines most people treat as separate. On one side, I engineer intelligent agents and automation systems with LangChain, LangGraph, n8n, Voiceflow and Botpress. On the other, I run Meta & Google ad accounts for Shopify brands, with a focus on getting the pixel, Conversions API and tracking actually right, since that is where most accounts quietly lose money.
On Fiverr I am a Level 2 seller with a 4.9★ rating, trusted by repeat clients across the US, Canada, Europe, Australia and South Africa. Recent results: a 5.52x ROAS on a bottom-of-funnel retargeting build, and CPM cut from $87 to $32.50 through structured creative testing.
I like problems that sit between marketing and engineering, the kind where a broken pixel is really an automation problem, and a slow manual workflow is really an opportunity for an agent to take over.
Pixel and CAPI setup, retargeting structure, creative testing, and ongoing optimization for Shopify brands.
PMax campaigns, conversion tracking cleanup, and policy compliance fixes.
Botpress and Voiceflow agents, plus RAG-based support and booking agents.
Connecting ad accounts, CRMs and APIs into automated pipelines that run without you.
Retrieval-augmented agents over your own docs and data, built with LangChain and LangGraph.
Fixing Event Match Quality, broken pixels, and Conversions API gaps that quietly cost ad accounts money.
Split bottom-of-funnel retargeting into three precise audiences and let the data show which one deserved the budget.
A 7-day creative test isolated two winning products. CPM went from an expensive guess to a proven number.
A summer traffic campaign aimed straight at the booking page for a Phoenix Airbnb host. Renewed for month two.
A RAG agent trained on the PAM 2006 contract, handling clause interpretation behind a gated client login.
Custom LoRA on RunPod for a WAN 2.2 image-to-video model, with ComfyUI workflow and lip-sync evaluation.
An n8n workflow that catches pixel and budget issues across live accounts before they cost money.
I highly recommend this fiver. mirzaumerikram understood what needed to be done better than I did. His work order was far more in depth than what I anticipated. He had great knowledge about Thrivecart.
It was a real pleasure working with Meta Omer. He has in depth product knowledge, is solution focused, and works on a very timely basis. Highly recommended.
Excellent work, thoughtful, concise, detailed. Will work with again.
Worked on 3 different projects with him. Every single time, expectations were met and exceeded.
Pleasure working with Meta Omer.
Excellent experience from start to finish. The technician was highly professional, communicated clearly throughout the project, and demonstrated an impressive in-depth knowledge of the system. He quickly understood the requirements, delivered exactly what was needed, and provided valuable insights along the way.
Umer is a professional freelancer, he knows what he's doing and have good understanding of meta and how things work. I am continuing with him for a follow up. Definitely recommend.
Très bon travail de son côté, je recommande fortement.
Most underperforming ad accounts share one root cause: Event Match Quality so low the algorithm is optimizing blind. Fix the data before touching the creative.
From real client audits →If the knowledge changes weekly, retrieval wins. Fine-tuning locks yesterday's answers into the weights. Every production agent I have shipped uses retrieval first.
From production builds →Full autopilot fails silently. Every workflow I build drafts the action and waits for approval before anything touches money, customers, or live campaigns.
From n8n pipelines →
