Senior Software Developer | Python, PHP, Ruby | Scalable Web Apps

Are you looking for a reliable, highly skilled senior software developer who delivers clean, scalable, and robust code? You've come to the right place.

I’m a seasoned Senior Software Developer with over 10 years of experience in building, maintaining, and optimizing software applications using Python, PHP, and Ruby. I specialize in back-end development, API integrations, and scalable SaaS platforms. My work powers everything from enterprise-grade systems to agile startups that are redefining their industries.

I bring to the table not just coding expertise, but a deep understanding of system architecture, software design principles, DevOps workflows, and long-term project lifecycle planning. I take pride in solving complex problems with simple, elegant solutions — all while keeping maintainability and performance in mind.

Core Technologies

Languages: Python (Flask, Django), PHP (Laravel, Symfony), Ruby (Rails, Sinatra)
Databases: PostgreSQL, MySQL, SQLite, MongoDB, Redis
Cloud/DevOps: AWS (EC2, Lambda, S3), Docker, GitHub Actions, CI/CD pipelines
API Development: RESTful APIs, GraphQL, OAuth2, third-party integrations
Testing & QA: Pytest, RSpec, PHPUnit, Postman, Test-Driven Development (TDD)
Other Tools: Git, Jira, Trello, Swagger, Linux CLI, NGINX, Apache, Vagrant

What I Do Best
✅ Full-Stack Web Development (with Back-End Focus)

From concept to deployment, I create applications that scale and perform. While I’m back-end focused, I’m comfortable working across the stack and collaborating with front-end developers using React, Vue, or even writing front-end code when needed.
✅ REST & GraphQL APIs

I design and implement robust, secure, and well-documented APIs that power mobile apps, third-party integrations, and modern web applications.
✅ SaaS Application Development

I have built and maintained multiple Software-as-a-Service (SaaS) platforms, handling multi-tenant architectures, billing systems (Stripe, PayPal), user roles, subscription logic, and automated scaling.
✅ Legacy System Modernization

Have an old PHP app that needs updating? Or a Ruby on Rails system that’s falling behind? I specialize in refactoring and upgrading legacy systems without disrupting existing users or data.
✅ DevOps & Automation

I use Docker, CI/CD tools, and cloud platforms like AWS to automate builds, tests, and deployments. That means faster releases, fewer bugs, and better uptime.
✅ Performance Optimization

Slow queries, unoptimized code, memory leaks — I hunt down performance bottlenecks and fix them. My work often results in 2x to 10x improvements in app speed and efficiency.

Why Clients Hire Me

Expert in Multiple Stacks: I bring true versatility with deep experience in Python, PHP, and Ruby — allowing me to adapt quickly and work with mixed tech stacks.

Clear Communication: I’m fluent in both English and technical language. You’ll always know what I’m doing and why.

Problem Solver: I don’t just “follow specs” — I think critically, suggest improvements, and anticipate issues before they arise.

Reliable Delivery: Deadlines are sacred to me. You’ll get your work done on time, or earlier, with quality that speaks for itself.

Long-Term Vision: I write code that's not just functional now but maintainable and scalable for the future.
