◆ 02 / the journey

3+ years building production software, from corporate platforms to client sites that pay the bills.

Wissensforte Technologies

Full Stack Developer

Remote

Node.jsTypeScriptReactPostgreSQLDockerGitHub Actions

Corporate software company, focused on internal tooling and process digitalization.

  • Lead developer and technical owner of OneHub: a corporate SSO ecosystem of 4 apps running across 9 production services (Node.js backends + React front ends), digitalizing the company's entire internal operations and saving ~29 hrs/month.
  • Designed centralized auth (SSO, 2FA, session management, rate limiting) and a cross-service RBAC system with full admin panel.
  • Turborepo monorepo with a parallel CI pipeline (lint, typecheck, test) on every push. Tests use HTTP contract assertions against a real Express app (not mocks), so refactors are safe to ship. Deploy runs via GitHub Actions SSH to a self-managed VPS: git reset --hard + selective git clean preserves .env while keeping the server in exact sync with the repo.
  • Built a Python automation for SAP-exported Excel datasets, cutting a manual finance process from ~2 hours to under 10 minutes.
  • Delivered an NFSe consultation API in .NET + MySQL; currently building FiscalHub, a multi-tenant fiscal document platform.
