I am a Senior Software Engineer with nearly 6 years of experience building and scaling high-throughput backends and fintech systems—currently at Paytm and previously at SCS. Throughout my career, I've specialized in handling high-concurrency Ruby on Rails architectures, scaling background jobs, optimizing complex databases, and building resilient payment pipelines. I help startups, engineering teams, and indie hackers solve their toughest backend challenges without the cost of hiring a full-time Lead Architect. 🔧 How I can help you: • Performance Tuning: Fixing slow Rails APIs, N+1 query bottlenecks, and PostgreSQL indexing strategy. • Scale & Reliability: Optimizing Sidekiq queues, Redis caching, and high-concurrency workloads. • Fintech & Payments: Designing fault-tolerant payment gateway integrations, webhooks, and retry logic. • Architecture Audits: Reviewing codebases for tech debt, security, and long-term scalability. Whether you need a quick 1:1 strategy call to unblock a performance issue or ongoing async architectural guidance, feel free to pick a slot below!
