Building product software for real workflows.

I build React Native, Next.js, and Node/NestJS products for finance, logistics, coaching, communications, and other places where the software has to feel finished after the demo is over.

01 / Selected work

Public products with clear context.

02 / Private systems

Private client work

Some projects cannot include public links or client names. These notes keep the focus on the kind of product, the systems involved, and the parts I worked on.

03 / Services

What I can help build

A practical view of the work I can take ownership of, from mobile apps to full-stack product features and release support.

01

Mobile app delivery

React Native apps for iOS and Android, including field workflows, offline-aware behavior, tablet layouts, store releases, and post-release fixes.

02

Full-stack product builds

Web products and internal tools where the frontend, backend, data model, auth, payments, and deployment need to move together.

Node/NestJS backends
Admin and client workflows

03

Payments, booking, and integrations

Product features that depend on third-party systems: Stripe, calendars, messaging channels, subscriptions, maps, AI APIs, and native SDKs.

Stabilization and handoff

The less flashy work that makes a release usable: bug fixing, performance cleanup, production behavior, documentation, and handoff support.

04 / Experience

Five years of product delivery, not a stack collage.

The pattern is consistent: translate messy requirements, build the product surface, wire the integrations, then stay close enough to make the release hold.

2020 - Present

Software Engineer - Ubicross Labs

Cross-platform product delivery across mobile and web apps in finance, logistics, communication, and operational tooling.

2022 - 2026

Freelance Software Engineer

End-to-end client work spanning discovery, implementation, integrations, deployment, and handoff.

05 / Education

Education and technical foundation

This is the background that shaped how I think through engineering problems.

2012 - 2019

Technical education in Yerevan

Software development, algorithms, databases, computer science, and the engineering fundamentals behind my product work.

06 / About

I like products where the hard part is below the first screen.

The visual surface matters, but the real test is what happens after someone starts relying on the product every day.

I build across mobile, web, and backend because product quality usually depends on how those pieces behave together.

My best work is practical: offline-aware mobile flows, polished release paths, payment and booking logic, dashboards, native modules, and the steady debugging that turns features into something a team can trust.

I am not trying to make every project look like a startup deck. I care more about clear ownership, honest product context, and a portfolio that feels like it belongs to a working engineer.

07 / Contact

If the product is real and the workflow is messy, I am interested.

Send the product problem first. The stack, timeline, and architecture decisions are easier to untangle once the actual workflow is on the table.
