Manoj Singh N.

I'm a backend-heavy full-stack engineer with **8+ years of experience** building scalable, cloud-native applications, with **6+ years specializing in Golang**. I've designed and delivered production systems across **e-commerce, crowdfunding, iGaming, social media, CRM, and SaaS**, taking products from architecture and database design to cloud infrastructure and deployment. I enjoy solving backend challenges around scalability, performance, and reliability—building systems that continue to perform as traffic and business requirements grow. ### 🔧 Backend Development I specialize in **Golang (Gin, Fiber, Mux, SQLC)** along with **Node.js** and **PHP**, building high-performance REST APIs, microservices, and backend platforms. My experience includes: * Designing scalable microservice architectures * API design and versioning * Authentication & authorization (JWT, OAuth) * Background job processing * Event-driven systems * Payment gateway integrations * Third-party API integrations * Performance optimization and profiling ### ⚙️ Distributed Systems & System Design Beyond writing code, I design systems that are reliable and scalable. My experience includes working with: * Microservices architecture * Caching strategies using Redis * Database indexing and query optimization * Load balancing and horizontal scaling * Distributed locking * Idempotent APIs * Eventual consistency * Message queues and asynchronous processing * Database replication and sharding concepts * High-availability backend services I'm also familiar with distributed systems concepts such as **CAP Theorem, Consistent Hashing, Saga Pattern, Two-Phase Commit, HyperLogLog, Bloom Filters, and rate-limiting algorithms**, and understand where these patterns are appropriate in real-world architectures. ### 🗄️ Databases I work extensively with: * PostgreSQL * MySQL * MongoDB * Redis I've designed database schemas from scratch, optimized slow queries, created indexing strategies, and built data models for high-traffic production applications. ### ☁️ Cloud Infrastructure (AWS & GCP) I build and maintain production cloud infrastructure on both AWS and GCP. **AWS** * EC2 * EKS * Lambda * S3 * RDS * VPC * Route 53 * Load Balancers * NAT Gateway * IAM * Secrets Manager * CloudWatch **GCP** * Compute Engine * GKE * Cloud Load Balancing * VPC I'm comfortable designing secure, scalable cloud environments rather than simply deploying applications. ### 🐳 DevOps My daily workflow includes: * Docker * Kubernetes * Terraform * CI/CD pipelines * Infrastructure as Code * Production deployments * Monitoring and troubleshooting * Linux server administration ### 🖥️ Frontend While backend is my primary strength, I'm comfortable delivering complete features using: * Next.js * Angular * React This allows me to own projects end-to-end when needed. ### 🛒 CMS & Integrations Experience integrating and customizing: * Shopify * WordPress * Third-party APIs * Payment providers * CRM systems ### Industries ✔️ E-commerce ✔️ Crowdfunding ✔️ iGaming / Gambling ✔️ Social Media ✔️ CRM ✔️ SaaS Clients typically hire me when they need someone who can think beyond implementation—someone who understands architecture, scalability, cloud infrastructure, and production reliability. I focus on writing maintainable code, communicating clearly, and delivering software that performs well in production, not just in development.
