I operate BizSafer, a specialized Production-First Engineering Lab. I focus on designing high-availability web architectures, robust full-stack applications, and lean container-native systems for platforms across North America, the United Kingdom, and Europe. I deliver industrial-grade reliability, sub-200ms edge latencies, and radical infrastructure cost reductions by bypassing bloated corporate cloud abstractions.
Most recently, I enforced architectural validation, zero-trust network perimeters, and secure edge data governance as a Lead Design Partner for enterprise cloud compliance layers, completing a clean corporate contract offboarding in June 2026.
- >99.9% Service Availability: Engineering redundant, zero single point of failure server footprints.
- <60s Mean Time to Resolution (MTTR): Deploying isolated environment parity and bulletproof error isolation.
- Sub-200ms Global Edge Latencies: Maximizing smart origin protection, CDN matrices, and performance tuning from data layers to edge nodes.
I maintain open-source reference blueprints proving the exact architectural performance and FinOps standards deployed to live production systems.
A secure enterprise file management SaaS demonstrating high-frequency payload routing and zero-egress cloud economics.
- Live Production: r2upload.io
- The FinOps Stack: Standalone Next.js edge environments, type-safe React/TypeScript components, Vite asset delivery, unified cleanly with a modern Laravel API core. Relational PostgreSQL persistence and stateful Redis clusters natively managed via Supervisord background queues.
- Orchestration & Edge: 100% Docker container isolation, orchestrated seamlessly via Kamal 2 (kamal-proxy atomic traffic swapping) over cost-effective VPS (Hetzner, DigitalOcean) and AWS EC2 nodes. Fronted by Cloudflare R2 Vaults to permanently eliminate data transfer egress fees.
The high-performance, zero-downtime corporate infrastructure blueprint powering the BizSafer Engineering Lab.
- Live Production: www.bizsafer.com
- The Decoupled Stack: Fully decoupled monorepo architecture separating Next.js edge routing from a high-throughput modern Laravel API core.
- Orchestration: Automated GitOps delivery via GitHub Actions continuous integration (CI/CD) pipelines pushing immutable Docker container states.
An enterprise-grade business operations platform engineered to govern complex manufacturing supply chains, interactive dashboards, and nationwide dealer lifecycles.
- Live Production: maxon.com.bd | nova-bd.com | admin.nova-bd.com | warranty.nova-bd.com
- The Architecture: Multi-tenant frontend nodes handling high-stakes business modules, backed by custom Cloudflare WAF perimeters and Layer 7 DDoS mitigation rules to deflect scrapers and safeguard backend processing domains.
