Emmanuel Umukoro

~/ Senior Software Engineer

Senior Software Engineer with 5+ years architecting production-grade systems at the intersection of Web3, AI/LLM agents, and scalable microservices. I lead end-to-end delivery of complex platforms — from a multi-tenant music royalty engine processing 50K+ daily events to blockchain-backed identity verification with zero-knowledge proofs — and ship AI agent frameworks (MCP, LangChain, Vercel AI SDK) in production.

01 Who I am

Engineer behind the product

I build the systems behind the product. Over the last five years I've architected and shipped production platforms across fintech, identity verification, real-time communication, music royalties and AI agents — usually owning the backend end-to-end and frequently the full stack, mobile and admin surfaces too.

My sweet spot is the intersection of three demanding domains: scalable microservices (event-driven pipelines, multi-tenant SaaS, horizontal real-time messaging), Web3 (Solidity, ZK-SNARKs, account abstraction, on-chain settlement), and AI/LLM agents (MCP servers, RAG infrastructure, LLM-powered automation). I care about API-first design, observability, and code that survives contact with real traffic.

I'm currently the Founding Backend Engineer at Synquanta, building an AI-driven lead-research-to-sales pipeline, while open-sourcing developer tooling like DeployX and expo-shipkit.

02 Core strengths

Four domains I go deep in

Most engineers pick one. My work lives at the overlap — and that intersection is where I do my most valuable work.

Scalable Microservices

Event-driven backends, multi-tenant SaaS, BullMQ/Kafka pipelines, and horizontally-scalable real-time messaging with Socket.io + Redis pub/sub.

01 / 04

Web3 & Blockchain

Solidity smart contracts, ZK-SNARK proofs (Circom + SnarkJS), account abstraction, gasless transactions, on-chain settlement and IPFS-anchored identity.

02 / 04

AI / LLM Agents

Production MCP servers (123+ typed tools), multi-tenant RAG infrastructure, Anthropic/OpenAI/Gemini integrations, and AI-driven automation with the Vercel AI SDK & LangChain.

03 / 04

Full-Stack & Mobile

Next.js/React/SvelteKit web, React Native + Expo cross-platform apps with native auth, IAP and OTA updates, plus admin dashboards — shipped across web, iOS and Android.

04 / 04
03 Where I've worked

A decade of shipping, role by role

Ten engagements across fintech, identity, music-tech, real estate and AI — most owning the backend end-to-end, several leading the full stack.
