DeFi Developer & Consultant - Liquidation System Design and Development for a Perpetual DEX
We collaborated with Dev Soor on the design of our off-chain liquidation system, a fully on-chain, mobile-first Perpetual DEX.
Dev oversaw the entire architectural definition process, starting from the analysis of our technical specifications through to the drafting of a detailed architecture that included data flow, choice of technologies, structuring of microservices, and management of the serverless infrastructure. He also accounted for the integration with The Graph, which is essential for retrieving historical on-chain events in the event of temporary system faults.
Throughout the collaboration, he proved to be punctual, precise, and very open to discussion, contributing significantly to the definition of the most suitable solution for our needs.
We are extremely satisfied with the work carried out and highly recommend Dev for any project.

Seeking Full-Stack Engineer for SaaS Platform with AI Integration
Dev immediately interpreted and understood our goal right from the start as a contractor. He helped us convert a vague and complicated idea into a detailed roadmap with defined and achievable steps. Without his expert-level knowledge about building SaaS solutions and high-level architecture design, we would be lost -- he went above and beyond with our contract.
I highly recommend Dev to anyone considering hiring him for their contract, whether it be building your idea from scratch or contributing to it. He will listen to your ideas, understand them, and do what needs to be done to make your ideas a reality.

AWS SAML SSO integration
Dev was able to complete the project successfully and exactly as specified. He is a very solid developer with significant experience in cloud architectures and the various services of cloud providers like AWS. Dev communicated and partnered with our in-house team well and was essentially acting as an extension of our team. Dev was also invited to be on conference calls with our customers during which he displayed great tact and composure in dealing with complex and challenging customer requests. We would certainly welcome the opportunity to work with Dev again.

Job Success
Queen Creek, United States - 1:10 am local time
I build production-grade AI applications end-to-end. Multi-agent orchestration with LangGraph and LangChain. RAG pipelines with vector search. Human-in-the-loop approval workflows. Full stack delivery with Next.js, React, Python, Node.js, MongoDB, Postgres, and AWS. One developer, one codebase, shipped to production with CI/CD.
I've been building MVPs for startups and solo founders for 8 years. Two years ago I went deep on multi-agent AI systems, and that's now the core of my practice.
What I've Built
AI-powered golf operations platform — 20+ coordinated agents built on LangGraph with tool usage, human approval workflows, RAG with MongoDB Atlas vector search, and checkpointed state management. Multi-tenant architecture on AWS serverless and containers, infrastructure managed with Pulumi IaC. Full Next.js/React frontend and two React Native mobile apps, real-time messaging, point-of-sale, analytics dashboards. CI/CD deployment on Vercel and AWS. From zero to production with real club users.
Medical AI chatbot — Custom RAG agent for medical professionals using verified clinical data. Built with LangChain, deployed on AWS. Went from kickoff to live product in 60 days. Automated patient onboarding and reduced support tickets from day one.
Healthcare patient monitoring MVP — Serverless architecture on AWS (Lambda, DynamoDB, API Gateway). Suggested product and UI changes during development that increased daily active usage 25% in the first month.
Equestrian social network — Real-time chat, social features, media sharing. Full MVP delivered 20% ahead of schedule. Scaled to hundreds of users in two weeks with zero downtime.
What I Actually Build (and Why It Matters)
Most AI app ideas sound simple but are architecturally hard. "I want an AI assistant that can check my calendar, email a client, and book a venue" — that's not one LLM call. That's an agent orchestration problem: state management across multiple tool-calling agents, error handling when one step fails, routing logic to pick the right agent for each subtask, and human checkpoints so nothing fires without approval. That's LangGraph, not a prompt.
This is the type of system I specialize in. If your product needs AI that goes beyond question-and-answer into actually doing things — browsing data, calling APIs, executing multi-step workflows, coordinating between specialized agents — that's my core work.
If You've Already Started Building
If you've prototyped something with Lovable, Replit, Bolt, Cursor, or any AI coding tool and now you're hitting walls — auth doesn't work right, the agent loops on edge cases, you can't deploy it reliably, it falls apart with multiple users — I can take what you've built and turn it into a real production system. You don't need to start over. I'll audit what you have, keep what works, and rebuild what needs proper engineering. This is increasingly common and it's a smart path — you validated the concept fast, now we make it real.
Technical Stack
AI/LLM orchestration: LangGraph, LangChain, OpenAI, Anthropic, Gemini, RAG, vector search, tool-use agents, human-in-the-loop workflows. Data and state: MongoDB (checkpointers, Atlas vector search), PostgreSQL, DynamoDB, MySQL, Redis. Backend: Python, Node.js, FastAPI, Express. Frontend: Next.js, React, React Native, Tailwind. Infrastructure: AWS (Lambda, ECS, S3, API Gateway), Docker, Pulumi, SST, Vercel. Practices: CI/CD, multi-tenant security, infrastructure as code, context engineering.
How I Work
We start with your product requirements. I'll map the agent architecture — which agents, which tools, which human checkpoints, which data sources — and give you a clear scope, timeline, and cost within 48 hours. You get weekly working demos of the actual application so we catch problems early. I prioritize what gets your product to users fastest and flag anything that's adding complexity without adding value.
⭐ Expert-Vetted — Top 1% on Upwork ⭐
If you're building an AI product that needs real multi-agent orchestration and full-stack delivery, message me with your project details. I'll respond within 24 hours with a concrete plan.
Steps for completing your project
After purchasing the project, send requirements so Dev can start the project.
Delivery time starts when Dev receives requirements from you.
Dev works on your project following the steps below.
Revisions may occur after the delivery date.
Gather requirements
Before you decide to work with me, I discuss your requirements and capture them in a document. This document also contains milestones and cost to develop. If it is an MVP, I will advise on how to break it up into phases to keep your cost manageable.
Make your decision
We go through 1-2 revisions of the documents until you are satisfied your main requirements have been captured correctly. If you decide to hire me, we sign a contract.
