Founder-led by design
Ilyros is structured around direct involvement. The person setting the standard for the work is also the person designing the interface, shaping the architecture, and carrying the implementation through launch.
About Jasin Marku
Founder, software engineer, and builder behind Ilyros.
Jasin Marku is a backend-focused software engineer in New York City and the founder of Ilyros, where he designs and builds websites, apps, APIs, internal tools, and product systems with direct end-to-end ownership.
Background
A founder profile shaped by technical depth, product judgment, and launched work.
Jasin builds with a strong bias toward clarity, technical depth, and work that holds up beyond the first impression.
His work moves across backend systems, product thinking, responsive interfaces, deployment, and the practical decisions that determine whether software feels serious or fragile.
Strong on systems and execution
The work combines backend engineering, product thinking, deployment, and interface craft. It is meant to be used, maintained, and extended, not just presented well in static screenshots.
Built for real use
The focus stays on software with real technical surface area: launched apps, production websites, APIs, internal tools, and systems that need to work cleanly under practical constraints.
Technical focus
Backend strength with enough range to ship the full product.
The emphasis is backend-focused software engineering: APIs, data, cloud deployment, and operational tools, supported by strong frontend and native app execution.
-
Backend engineering
Python, FastAPI, SQLAlchemy, PostgreSQL, MySQL, Supabase, API design, data workflows, and production-oriented service architecture.
-
Frontend and product UI
Astro, Tailwind CSS, JavaScript, responsive interface systems, deployment-ready websites, and polished product surfaces.
-
Native and mobile
Swift, SwiftUI, Core Data, App Store-oriented product work, and mobile interfaces with real persistence and release paths.
-
Cloud, DevOps, and AI tooling
AWS, Docker, Git, CI/CD, OpenAI API, Claude API, LangChain, and Structured Outputs for practical tooling and automation.
Selected proof
Shipped and active work with real technical surface area.
This is proof of capability rather than a case-study archive: shipped apps, backend systems, product software, and websites built with real implementation depth.
Selected work
CigarBoxd
A production-minded app project representing Jasin's product engineering focus across interface design, data modeling, backend systems, and release-oriented execution.
Selected work
DocFlow API
A backend-focused API project centered on document workflows, structured data, and practical service design using Python-oriented software engineering patterns.
Shipped
VirtuTrade
A public iOS crypto simulator with market data, portfolio tracking, simulated trading, persistence, and App Store release work handled end to end.
Shipped
Facade restoration website rebuild
A full-scope website rebuild for a New York contractor, built to feel more credible, more intentional, and more operationally sound than a standard template-driven presence.
