Product Engineering
Web apps, APIs and the systems behind them.
I’m Sina — a developer, designer and builder focused on creating useful digital products, from websites and databases to full software systems.
I like the whole arc of a build: understanding the problem, designing the shape of the solution, and engineering something that actually holds up once it’s in people’s hands. I’m not just freelancing project to project — I’m building toward something.
Web apps, APIs and the systems behind them.
Data models, internal tools, operational software.
Identity, layout and the way a product feels.
Digital products, software systems and technology solutions.
2026 —Payroll & HR platform; architecture and delivery.
2026 — PresentClient web, brand and creative work.
2021 — PresentThe four things I get hired for — and everything on the bench that builds them.
Sites and platforms that load fast, read well on a phone, and don’t break when traffic shows up.
Payroll, records, operations. The internal software a business actually runs on.
Identity, layout, social and motion — so the product looks like it belongs to someone.
Bring the problem. If nothing off the shelf fits it, I’ll build the thing that does.
Python, Flask, JavaScript, React and PostgreSQL for the build; Figma and the Adobe suite for the way it looks; Git, Netlify and Render for getting it shipped and keeping it up.

Payroll & HR platform. Import payrolls by company, review warnings, approve runs and deliver every payslip to the worker — all in one place. A Sinaforte Technologies product.
Tell me what you’re trying to build and roughly where it stands. I read every message and reply myself.
