Strategic Value
"We hired Arsen to build something specific, but he kept asking questions that made us realize we were about to build the wrong thing entirely. We changed direction. That decision saved us a lot of money."

How I Work with Agencies
I work white-label for design, product, and dev agencies. Your client never sees me — I sign your NDA, ship to your repo, you ship to your client.
White-label only
Your client never sees me. I sign your NDA, work under your brand, disappear after delivery.
Ship to your repo
I push to your GitHub / GitLab. Your CI, your conventions, your PR flow.
Async-first
Written specs in Slack, Linear, or GitHub. No standups, no client calls. Just shipped code.
Flexible pricing
$60–80/hr depending on scope, or fixed-price packages from $3,500. 50% upfront. Open NDA.

The Person Behind the Code
I've been shipping production code since 2018 — across SaaS, e-commerce, finance, and media. Started with WordPress because that's what paid back then, moved to React, Laravel, and Go as projects got more serious. Two years as a remote engineer on a NY-based product team taught me how to ship at scale. Now I work independently with clients across Europe and the US.
I'm AI-native by default — I use OpenAI and Anthropic APIs every day, not as marketing buzzwords. I build and run LLM systems myself: agents with tool access, retrieval over my own data, model routing and cost control. That's how I ship in weeks what usually takes months, without compromising code quality.
🛡️ 30-Day Post-Launch Support, Included Free
After launch, I don't just disappear. For a full month I'll fix bugs, make tweaks, and sort out anything that needs adjusting. No extra charge.

My Work
Some of the projects I've built for real clients.
Gold traders in Yerevan and Moscow were stuck with prices that refreshed every 30 seconds. In a fast market, a 30-second-old price is too old to trade on.

Gold Center
Armenia's biggest mattress manufacturer was selling most of their product through retail stores. They wanted a direct-to-consumer channel that actually worked.
E-commerceReactNext.js
Sleep House
Armenia's most-read news site was crashing during breaking news events — exactly when it needed to be up most.

"We were getting conflicting opinions from different developers on what was actually wrong. Arsen came in, looked at the system, and gave us a clear answer in a few hours. First time anyone had done that."
