My core expertise is Ruby on Rails, React, Next.js, Node.js, PostgreSQL, Redis, and cloud infrastructure. I enjoy understanding complex business requirements, solving difficult technical problems, and turning them into clean, scalable, and maintainable software. Over the years, I’ve worked on a wide range of production applications, including multi-tenant SaaS platforms, payment systems, analytics and reporting platforms, role-based applications, API-driven systems, scheduling workflows, online examination platforms, and data-heavy applications. ## What I can help you with * Ruby on Rails — Rails 5–8, Hotwire, Turbo, Stimulus, ActionCable * Full-Stack Development — React, Next.js, Node.js, JavaScript/TypeScript * Backend & APIs — REST APIs, third-party integrations, webhooks * Database — PostgreSQL, MySQL, MongoDB, Redis * Payments — Stripe and other payment integrations * SaaS & Architecture — Multi-tenancy, authentication, roles & permissions * Background Processing — Sidekiq, Redis, asynchronous workflows * Frontend — React, Next.js, Tailwind CSS, responsive UI * Cloud & Deployment — AWS, Azure, Heroku, DigitalOcean, Docker * Testing & Quality — RSpec, TDD, BDD, automated testing, RuboCop * CI/CD & Version Control — GitHub, GitLab, Bitbucket, CI/CD pipelines * Real-Time Applications — ActionCable, WebSockets, notifications * Reporting & Analytics — Dashboards, charts, data-driven applications I’m particularly experienced with existing production applications. Whether you need to build a new feature, modernize an older application, integrate a third-party service, improve performance, troubleshoot a production issue, or gradually evolve an existing architecture, I can work within the current system and make improvements without unnecessarily disrupting working functionality. I also have extensive experience working remotely with distributed teams, managing my own workload, communicating clearly, and taking ownership of tasks from planning and implementation through testing, deployment, and production support. I believe good engineering is not just about writing code—it’s about understanding *why* something needs to be built, choosing the right approach, and delivering a solution that supports the business as it grows.
