I help SaaS startups scale Ruby on Rails applications to handle real production load. 13+ yrs experience in Rails, AI integrations, cloud & DevOps architecture. If your app is getting slow, breaking in production, or not handling growth properly, I can help fix and scale it. 💡 What I do : • Scale Ruby on Rails applications (high traffic, background jobs, DB optimisation) • Improve performance (slow queries, N+1 issues, caching, indexing) • Design scalable system architecture (monolith → modular / microservices when needed) • Setup AWS cloud infrastructure (EC2, RDS, S3, scaling strategies) • DevOps & CI/CD pipelines (Docker, deployment automation, monitoring) • AI integrations (LLMs, automation workflows, SaaS intelligence features) • Debug complex production issues (memory leaks, downtime, infra bottlenecks) • Refactor legacy Rails apps into clean, maintainable systems ⚙️ Core Tech Stack : Ruby on Rails, PostgreSQL, MySQL, Redis Amazon Web Services (AWS), Docker, CI/CD Sidekiq, REST APIs, Microservices AI Integration (LLMs, automation) React / Vue (when required) 📈 Results I typically deliver: • Faster application performance & reduced load time • Stable systems under high traffic • Reduced production bugs & debugging time • Scalable architecture ready for growth • Better infrastructure with controlled cloud cost 🤝 How I work: - I work like a technical partner, not just a developer. - Focus on long-term scalability (not quick hacks) - Clear communication (no unnecessary jargon) - Proactive suggestions to improve system - Strong ownership of production systems If you're building or scaling a SaaS product and need someone who understands real production challenges, let’s connect.
