Saiful Islam

Software engineer in Dhaka, Bangladesh (UTC+6), open to remote. 3.5+ years building reactive, signals-first interfaces in Angular and React — and the .NET / Node behind them, down to the database and the monitoring that watches it.

Portfolio LinkedIn Email CampusQ Resume

Four enterprise ERP platforms, a multi-tenant SaaS, and 6+ products live, across three companies since 2023 — each running behind its own self-hosted observability stack. Modules shipped: access control, accounting, HR, production, inventory on the ERP side; deviation, checklist, handbook, compliance, settings on the QMS side. I work AI-native — Claude, Cursor, Ollama and OpenCode as a force multiplier, not a shortcut.

Things I shipped on my own time

Project What it is Status
CampusQ Multi-tenant coaching-management SaaS — tenant isolation via Postgres RLS, bitmask RBAC, online exams, bKash/Nagad payments, PWA + push, bilingual (en/bn). Runs behind a self-hosted LGTM stack: OpenTelemetry traces into Tempo, Prometheus metrics, Loki logs, Grafana alerts to Telegram. .NET 10 · Angular 21 · Next.js 16 live
Rent-ERP Single-org property-management ERP across three surfaces — .NET 10 modular monolith, Angular 21 admin console, and a React Native app serving tenants & staff. Property hierarchy, per-tenant billing with bKash, accounting, HRM, SMS/FCM notifications. .NET 10 · Angular 21 · React Native source private
ngx-primeng-toolkit Open-source Angular library — parameterized query/table state, memoized data & reusable utilities, released to npm with automated CI/CD. published
DebuggerMind Commerce In-house white-label storefront (Next.js 15 + .NET API) — international build and a localized Bengali variant maintained in parallel, 6 languages. live
