Architecting resilient
web ecosystems
at national scale.
Hi, I'm Md Shafiul Bashar. Senior Software Engineer & Full-Stack Architect with 8+ years leading mission-critical web platforms, nationwide railway ticketing systems, and multi-tenant SaaS engines.

Featured Case Studies
Selected high-throughput platforms, real-time booking engines, and mission-critical systems deployed in production.
Bangladesh Railway e-Ticket & Rail Sheba
National rail ticketing single page application handling millions of daily searches and peak-load seat reservations.
The legacy system struggled under catastrophic traffic spikes (millions of concurrent hits during Eid festivals), leading to race conditions in seat allocations and user lockouts.
Architected and converted the platform into a reactive Angular PWA with state-driven seat locking via WebSockets, intelligent retry mechanisms, offline ticket caching, and localized language support.
Shohoz Bus Ticketing Platform
Real-time multi-operator bus booking engine across nationwide routes with dynamic interactive seating layout.
Fragmented operator inventory systems caused booking latencies and inventory sync mismatches between web clients and physical counters.
Designed an interactive seat selection canvas with optimistic locking, seamless multi-leg routing, and automated Google Tag Manager tracking for conversion analytics.
Self-Service Ticket Vending Machine (TVM)
Unattended touchscreen kiosk application running in major railway terminals with hardware printer and cash/card integration.
Hardware lockups and unreliable local printing led to long queues at station kiosks when internet connectivity dipped.
Engineered an offline-first kiosk shell with automated crash recovery, hardware polling daemon for ESC/POS thermal printers, and real-time transaction reconciliation.
Global Student Migration & Consultation Hub
Comprehensive student recruitment and immigration portal with automated document evaluation workflows.
Inefficient manual document intake via email caused immigration consultant backlogs and lost client leads.
Built an end-to-end client onboarding funnel with automated eligibility scoring, interactive document checklist validation, and Stripe billing.
Engineering with precision, clarity, and scale.
I am a Senior Software Engineer specializing in modern reactive frontend systems (Angular 21/22, Zoneless, Signals) paired with distributed backends (Laravel, Node.js, Python).
Over 8+ years, I have architected systems powering millions of transactions monthly, built touch-screen hardware kiosk platforms, and designed high-throughput booking flows where failure is not an option.
