Ahmad Bagheri

I'm a senior full-stack engineer with 7+ years of experience building integration-heavy systems for ERP, fintech, and traditional enterprise environments. I specialize in NetSuite/SuiteScript integrations, TypeScript on both ends (NestJS + React/Next.js), and the production tools that wrap them.

Currently at Barriertek, I'm the sole engineer on Woody Portal — a manufacturer customer portal that replaces phone-based order coordination, whiteboard production scheduling, and per-team Excel sheets with a unified real-time dashboard for distributors, truckers, production workers, and the office team. Bi-directional NetSuite integration via SuiteScript RESTlets; currently in partial launch with full external rollout targeted for October 2026.

Before that, I led the frontend rebuild at DexTrading(a crypto analytics platform), shipped an in-house content platform that became a primary acquisition channel, and built a Django-backed AI Q&A API tied to subscription growth. Earlier I worked at Chargoon — an Iranian ERP vendor — migrating legacy modules to a React + .NET stack alongside a 15-engineer team.

I'm comfortable owning architecture, infrastructure, and delivery end-to-end — from Postgres schema and API design through deployment on Coolify with Linux and Ansible, to CI/CD and the front-end polish. I'm available for contract and part-time engagements (10–25 hrs/week), remote, GMT+3 with comfortable overlap with US Eastern and Western Europe.
