20 years in software development. 15+ years building full-stack Ruby on Rails applications. Former CTO, project manager, and company founder.
I take products from rough requirements to production: planning, architecture, development, testing, code review, deployment, and ongoing improvement.
I work best with clients who need an experienced engineer who can understand the business problem, make sound technical decisions, and deliver without constant supervision.
### Summary
I am a **Principal Product Engineer** and hands-on Ruby on Rails specialist, amplified by AI.
I can help with:
* Building complete Rails/Php/React features and applications
* Turning unclear requirements into practical development plans
* Architecture and technical decisions
* Performance tuning and database optimization
* Code reviews and team guidance
* Production issues and difficult bugs
* DevOps, deployments, monitoring, and infrastructure
* Modernizing legacy Rails applications
I use AI where it helps me research, plan, test, and deliver faster, but I remain fully responsible for every technical decision and result.
Recent projects include **AzinvSpace**, an inventory management platform, and **Azletics**, an adaptive fitness application. Both are available in my portfolio.
I am a good fit when you need senior ownership, direct communication, fast execution, and production-ready work.
### Core strengths
* **Ruby on Rails/PHP/React:** architecture, development, upgrades, and maintenance
* **Full-stack delivery:** backend, frontend, APIs, integrations, and background jobs
* A-Z Delivery: turn fuzzy requirements into clean plan, then to tested Rails features, nice and fast code.
* Scalability & performance: Tune with PostgreSQL/Redis, background jobs, caching, N+1 eradication, P95/P99 focus
* API design: resilient REST/GraphQL, rate-limiting, idempotency, and observability
* Security: OWASP mindset, secure auth (Devise/OAuth2/OIDC/JWT), secrets hygiene(plus a bit more security stuff)
* DevOps: Dockerized apps, zero-downtime deploys, repeatable infra, clear runbooks & alerts
* **Quality:** RSpec, system tests, code review, and static analysis
