Key Skills

Combining 10+ years of software engineering expertise with modern full-stack software development, specializing in React/Ember.js frontends and Rails/Django backends. Increasingly building enterprise-grade solutions that deliver value across the entire software lifecycle.

Full Stack Development

I build scalable full-stack solutions in Python (Django, Django REST API), Ruby (Rails, Sinatra), React (Next.js, TypeScript) and others at any level of frontend/backend split. I have expertise in object-oriented programming principles, software design patterns (DRY, KISS), and networked applications using RESTful APIs.

Software Architecture

I design modular, resilient systems with a focus on scalability and maintainability. I prioritize clean code architecture, ensuring separation of concerns, robust error handling, and efficient data flow. By leveraging cloud infrastructure and CI/CD pipelines, I build systems that are not just performant, but also easy to test and deploy.

Stakeholder Management

Working closely with Product Managers and Agile leaders, I can confidently distill user requirements into concrete tasks that are accurately scoped for development time. Throughought the dev lifecycle, I proactively communicate with PMs about timelines and blockers, ensuring features get shipped on time and on spec.

Database Optimization

I implement performant applications that rely on PostgreSQL, MySQL or SQLite database technologies. End to end schema management and efficiency gains by reducing N+1 queries, prefetching 1-M and M-M relationships and indexing are some strategies I employ to optimize DB efficiency and scalability.

Professional Experience

My core professional experience includes software engineering related internships and full time roles, from 2012 to the present day.
