Software engineer with full-stack and platform depth.

I’m Jasin Marku, based in New York. My work spans interfaces, backend systems, data integration, and the infrastructure underneath them. I work in a client-embedded enterprise engagement and build independent products and client work through Ilyros.

From discovery to production ownership.

In my current enterprise engagement, I started with stakeholder discovery, AI workflow design, prototypes, and acceptance criteria. The work evolved into hands-on software engineering: implementing applications, integrating data, and taking responsibility for deployment and handoff. This professional work is separate from Ilyros.

Selected engineering experience

Public summaries of work in that enterprise engagement.

Leadership analytics, from warehouse to interface.

I built and helped own an analytics platform spanning React and TypeScript, a Node.js backend, and Redshift data. I moved dashboard delivery toward scheduled, precomputed snapshots, so the interface could consume aggregated data without waiting on large live-query responses.

A database adapter supported PostgreSQL for local development and the Redshift Data API. I validated parity through row counts, identifiers, and normalized values, with explicit failures when parity could not be established. Application calculations were aligned with authoritative metric definitions, with deployment and handoff documentation alongside the code.

Increasing ownership across application layers.

Recent work connects React interfaces, FastAPI services, application and rules-engine logic, and warehouse and Salesforce integrations. It increasingly includes authentication, infrastructure, tagged releases, and deployment—not just a single layer of the application.

The infrastructure underneath the application.

I’ve designed and deployed AWS infrastructure using CDK across EC2 and serverless architectures. That work includes networking, IAM, secrets management, deployment, hardening, runbooks, and engineering handoff.

For one internal business application, my ownership was the cloud infrastructure and deployment. I did not author the application’s full business logic.

AI workflows with a human review path.

Earlier work translated operational requirements into AI-assisted workflows using Bedrock, Claude, LangChain, and LangGraph. Structured Pydantic schemas, evaluation, retained reasoning, and auditable human overrides made review part of the workflow. Discovery, specifications, and implementation planning were part of that work too.

Own the path into use.

I start by defining the problem and the constraints, then break the system into work that can be implemented and checked. Integration, testing, and data validation inform the build; deployment, production verification, documentation, and handoff are part of finishing it.

My workflow includes Claude Code, Cursor, and coding agents, supported by repository instructions, scoped tasks, branches and worktrees, and automated checks. Agents accelerate implementation; I remain responsible for architecture, constraints, integration, debugging, and verifying what reaches production.

Ilyros is my independent studio.

It’s where I build independent products and take on client work. VirtuTrade is my released native iOS product. My website work includes Colgate Restoration, Lens by Ley, and Remi Interiors. Each project has its own account of what I contributed.

Through Ilyros, you work directly with me on scope, design, engineering, and delivery. For engineering or product-team opportunities, you can also reach me personally.
