Abdul S.
Full Stack Engineer | Ruby on Rails & Next.js | AI-Powered SaaS Apps
Most development teams struggle to move fast without breaking things. I help SaaS and product teams ship reliable, well-architected Rails applications, whether they're starting from scratch or scaling up. I'm a full-stack Ruby on Rails engineer with 5+ years of experience across AI platforms, e-commerce, FinTech, healthcare, and document automation. My recent work includes building GiniNow, an AI-powered expert matching platform using OpenAI and advanced search algorithms, alongside SaaS tools, marketplace systems, and API-heavy applications. I've worked across the full stack and the full lifecycle architecture, feature development, API integrations, BDD testing, code reviews, team mentoring, and cloud deployments. What I built: - AI-integrated web apps (OpenAI, Firebase, advanced search) - SaaS platforms and internal tools - E-commerce and marketplace systems - Document automation and digital signature workflows - REST APIs and third-party integrations (Stripe, Twilio, DocuSign, SendGrid) Stack: Ruby on Rails · React · Next.js · Hotwire/Stimulus · PostgreSQL · AWS · Heroku · RSpec · Tailwind My last engagement was a 2-year partnership with a single client, which means I work like a long-term team member, not a hired gun chasing the next contract. If you need someone who takes ownership and not just tickets, let's talk.
