You will get A fast and reliable Ruby on Rails bug fix and optimization service


Project details
You will get a reliable and efficient Ruby on Rails bug fixing and optimization service tailored to your application. With 12+ years of experience working on SaaS platforms, backend systems, APIs, and production applications, I focus on identifying issues quickly and delivering stable, maintainable solutions.
I can help fix bugs, improve backend logic, optimize PostgreSQL queries, clean up unstable flows, and improve overall application performance. I’m comfortable working with existing and partially completed Rails applications, including production debugging and issue resolution.
My approach is simple: understand the issue, identify the root cause, fix it cleanly, and ensure the application behaves reliably. If you need someone who can take ownership and solve problems efficiently, I’m here to help.

About Rajiv
Senior Ruby on Rails Engineer | SaaS | REST APIs | AWS | PostgreSQL
Dewas, India - 12:20 am local time
Expert in backend architecture, REST API development, PostgreSQL optimization, and background job processing using Sidekiq and ActiveJob.
Strong track record of improving system performance, optimizing API throughput, and building reliable, high-availability systems used in production environments.
Experienced working with distributed teams and delivering high-impact features in fast-paced Agile environments.
Proven strengths:
Quickly taking over partially built codebases (Base44, React, or custom apps), fixing bugs, completing features, and deploying to production in 7–14 days
Building scalable marketplace platforms, financial/donation systems, warehouse management (used by TATA & Reliance), and video upload/playback workflows
Third-party integrations (Stripe, Razorpay, OAuth, Webhooks, AWS S3 pre-signed URLs)
Performance optimization, modular architecture, and containerized deployments (Docker, AWS EC2/RDS/S3, Heroku, Control Plane)
React.js, Vue.js & Stimulus.js for responsive frontend
I specialize in fast execution — whether it’s finalizing a Base44/React app, exposing APIs to AWS Marketplace, setting up LLM-ready infrastructure, or stabilizing any existing web application. Always focused on clean code, reliability, and long-term scalability.
Currently open to SaaS, sports-tech, AI-enabled platforms, cloud-native projects, and quick-turnaround deployment work.
