Software engineer · open to research opportunities
Building backend and data systems since 2020. Next: quantum computing research.
Sina Qasempour / EngineerI build real-world systems and explore the ideas beneath them. Six years in software, enterprise platforms, and startup leadership have shaped my practice. Today, that curiosity also leads me into Quantum Computing.
01 Selected work
Organizational platforms, startup responsibility, and operational products.
01 / Enterprise systems
Connecting organizational work, priorities, and performance through software that fits the way teams operate.
Inside the systemThe Rahtal platform itself is a private company system. The public source is the integration companion, the first version of a planned in-product agent; the diagram shows that integration boundary.
CTO experience, connecting startup responsibility with hands-on work on the product's core services.
A connected backend for customer operations, municipal services, pricing, and support across existing systems.
Making municipal services understandable through connected account, billing, and citizen-request workflows.
A product for following tire condition and maintenance history across heavy-vehicle fleets.
02 Engineering journey
Chapters in how I think about engineering, rather than a dated employment timeline.
Chapter 01 · Learning by building
Turning requirements into working products established my foundation in software. Interfaces, application logic, and data became connected parts of the same problem.
Working software · Product behavior
Make the idea concrete enough to examine.
A growing engineering perspective
03 Computing exploration
How does a different representation change what we can compute? Quantum Computing is one of my strongest long-term interests. For now, the work is study, simulation, and carefully bounded experiments.
An independent research study using exact local simulation, submitted to Machine Learning: Science and Technology (IOP Publishing) and not accepted. Not a quantum-hardware benchmark or a clinical application.
04 A working record
A selected reading list of systems, tools, and experiments. Each repository reveals a different engineering question.
A Python SDK on PyPI for Persian and English chat reporting. The model only extracts intent; deterministic code authorizes it and compiles parameterized, read-only SQL. A live showcase records each stage, including attacks.
SageQLA modular portal backend with customer workflows, migrations, and integration bridges.
zaraamad-portal-beDjango support tooling with city-specific database routing and connection checks.
zaraamad-support-panel-beSQL Server query automation with timeouts, categorized failures, and structured reports.
