Building a Scalable Bike Sharing Platform (500K Users)

<h2>🚲 Dockless Bike Sharing Platform (500K+ Users)</h2><h3>🟢 Executive Summary</h3><p>Designed and built a full-stack dockless bike-sharing platform, enabling over 500,000 users to rent bikes anywhere in the city.</p><p>Led architecture and product decisions across mobile, backend, and IoT systems, delivering a scalable, real-time platform with payment, geofencing, and smart lock integration.</p><h3>🟡 Problem & Constraints</h3><p>When I joined, the system was:</p><ul><li><p>Station-based (no free-floating)</p></li><li><p>No customer-facing app</p></li><li><p>IoT locks unreliable and dependent on SMS-triggered heartbeats</p></li><li><p>High risk of theft and misuse</p></li><li><p>Payment infrastructure constrained to local providers</p></li></ul><p>👉 The goal was to transform this into a <strong>real-time, city-scale mobility platform</strong>.</p><h2>System Architecture for Real-Time IoT Platform</h2><h3>1. Real-time Communication (REST → WebSocket)</h3><ul><li><p>❌ REST required SMS-triggered wake-ups → unreliable & expensive</p></li><li><p>✅ Switched to WebSocket for persistent connection</p></li></ul><p><strong>Trade-off:</strong></p><ul><li><p></p></li></ul><ul><li><p>Real-time control & monitoring</p></li></ul><ul><li><p>− Increased infra complexity & connection management</p></li></ul><h3>2. Unlock Latency Optimization</h3><ul><li><p>Initial unlock latency: ~1800ms (network dependent)</p></li><li><p>Problem: noticeable delay in user experience</p></li></ul><p><strong>Solution:</strong></p><ul><li><p>Introduced Bluetooth fallback for local unlock</p></li></ul><p><strong>Impact:</strong></p><ul><li><p>Reduced perceived latency significantly</p></li><li><p>Improved reliability in poor network conditions</p></li></ul><h3>3. Wallet as a Microservice</h3><ul><li><p>Built wallet as a separate service early</p></li></ul><p><strong>Trade-off:</strong></p><ul><li><p>− Higher initial complexity</p></li><li><p></p></li></ul><ul><li><p>Enabled future scalability (super-app readiness)</p></li></ul><h3>4. Prepaid (Pay-as-you-go) Model</h3><ul><li><p>Users must charge wallet before ride</p></li></ul><p><strong>Trade-off:</strong></p><ul><li><p></p></li></ul><ul><li><p>Reduced fraud risk</p></li></ul><ul><li><p>− Added friction to onboarding</p></li></ul><h3>5. Cross-platform Strategy</h3><ul><li><p>Android → React Native</p></li><li><p>iOS → PWA</p></li></ul><p><strong>Reason:</strong></p><ul><li><p>Faster time-to-market under limited resources</p></li></ul><p></p><h2>WebSocket vs REST in IoT Systems</h2><h2>🟣 System Design Overview</h2><ul><li><p>Backend: Laravel + MySQL</p></li><li><p>API Layer: REST + WebSocket</p></li><li><p>IoT: SIM-enabled locks with solar charging</p></li><li><p>Geo-fencing: OpenStreetMap (point-in-polygon)</p></li></ul><p><strong>Flow:</strong></p><p>User → API → WebSocket → Lock</p><p>Lock → WebSocket → Backend (location, status, battery)</p><h3>🟠 Key Challenges</h3><h3>IoT Reliability</h3><ul><li><p>Locks previously required SMS to re-establish connection</p></li><li><p>Caused delays and operational overhead</p></li></ul><p>👉 Solved by moving to persistent WebSocket connections</p><h3>Identity Verification at Scale</h3><ul><li><p>Manual verification was not scalable</p></li></ul><p><strong>Solution:</strong></p><ul><li><p>OpenCV-based automation (~90% coverage)</p></li><li><p>Government API for validation</p></li></ul><h3>DevOps Scaling (Pet → Cattle problem)</h3><ul><li><p>Early infra treated servers as “pets”</p></li><li><p>Scaling caused instability and operational overhead</p></li></ul><p>👉 Required shift toward more automated and reproducible infrastructure</p><h3>🔴 Impact</h3><ul><li><p>500,000+ users within ~1 year</p></li><li><p>Peak: 800+ rides/day</p></li><li><p>System downtime: ~3%</p></li><li><p>90% automated identity verification</p></li><li><p>Significant reduction in IoT communication delays</p></li></ul><h3>⚫ My Role</h3><ul><li><p>Led a 5-person engineering team (4 backend + myself)</p></li><li><p>Owned:</p><ul><li><p>System architecture</p></li><li><p>Product decisions</p></li><li><p>IoT integration strategy</p></li></ul></li><li><p>Coordinated with remote IoT team (China)</p></li></ul><p></p>

What Clients Say

“Nima delivered our MVP in 6 weeks — on budget, on time, and with code quality we're still building on two years later. Best technical partner we've ever worked with.”

Sarah M.

CTO, FinTech Startup

“Our conversion rate went from 1.8% to 6.2% after Nima rebuilt our checkout flow. That's €300k in additional annual revenue from a single engagement.”

Marcus K.

Founder, E-commerce Brand

“Nima doesn't just write code — he understands business. He pushed back on two features that would have cost us time and added nothing to user value. Rare to find that.”

Lisa T.

Product Manager, SaaS Platform
