Backend for Webapp
Anas worked fast and communicated frequently and made sure I was updated. His code is clean and well documented, it was a pleasure to work with him.
About Anas
Agentic AI Engineer | AI Agents, Automation, RAG & LLM Apps
Islamabad, Pakistan - 2:36 pm local time
Most AI agents break the moment they meet real users, real data, and real edge cases. I build the unglamorous parts that make them survive: evals, guardrails, fallbacks, confirmation gates, and clean integration into your existing stack - so you get a system you can trust, not a black box you're afraid to touch.
WHAT I BUILD
• Autonomous AI agents & multi-agent systems - tool/function calling, orchestration, memory
• RAG systems & AI chatbots grounded in your documents and live app data, with cited answers
• LLM features inside existing products (OpenAI, Anthropic Claude, Gemini, open-source)
• Agent guardrails, evals & observability - so you can see and trust what's running
• The backend behind it all: Node.js, NestJS, Go, PostgreSQL, Redis, Kafka, GCP
PROOF
I currently lead engineering for a consumer family-safety AI product: I architected the context layer that grounds the assistant in live app state, designed the guardrails that let agents act safely on a parent's behalf, and scaled to 30+ audited agent actions in production. Earlier: cut an API's latency 70% (1.2s to ~350ms) for a platform serving 1,000+ users, and shipped checkout features that helped a fintech startup close a $10M round. On Upwork: $50K+ earned across long-term engagements, 5.0 rating, 1,900+ hours. That AI work stands on seven years of full-stack foundations - Node.js, Go, React, PostgreSQL - including 1,900+ hours of production backend work on Upwork itself.
HOW I WORK
I start with the workflow, not the tech. If an agent pays for itself, I'll tell you how I'd build it - architecture, effort, and monthly running costs. If it doesn't, I'll tell you that too, before you spend money. Every build ships with evals, monitoring, documentation, and a clean handover. I also write about agent reliability, observability, and memory vs. context on my engineering blog.
Have a manual, repetitive, expensive workflow that should run itself - or an AI agent that isn't behaving in production? Message me with what's eating your team's time, and I'll tell you exactly how I'd approach it.
Steps for completing your project
After purchasing the project, send requirements so Anas can start the project.
Delivery time starts when Anas receives requirements from you.
Anas works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements Gathering Phase
Before starting any development work, I will take the time to completely understand your requirements in detail to see if it fits my expertise. This could include discussion on chat or in a meeting
Development Phase
After the scope is approved, development begins. This includes Full Stack development of new apps/sites, updates/bug fixes. You'd be able to get progress updates regularly during this phase.
