Full-stack developer · infrastructure, developer tools and multilingual products · Moscow
I work on proxy and network infrastructure at NodeMaven, and I ship
products in four writing systems.
The work I am proudest of measures something and then publishes what it measured,
including the parts that did not go my way.

Is your proxy actually hiding you? A leak-detection tool that catches what a proxy quietly fails to cover: WebRTC over STUN and TURN, HTTP/3 over QUIC, and addresses the browser reports but the network contradicts.
The design rule is that it never trusts the browser. Every channel also has a server-side observation, and a leak is defined as the disagreement between the two.

Four containerised services behind one docker compose up, 50 tests across a CI
matrix, self-hostable end to end. Observations are keyed to a random token and expire
after 120 seconds, which the README states plainly, alongside the things the tool
deliberately does not check. A leak-detection tool that only lists its wins is not
one you should trust.

An AI voice receptionist that answers calls, holds a conversation, and acts while the call is still in progress. The conversation module runs function-calling against a task layer, so a call can create a record or fire a notification before it ends, then hand off to a human when it should.
NestJS organised by domain rather than by file type: telephony (Twilio webhooks),
conversation (AI client, prompts, function calls), tasks, calls, notifications
(Telegram and email), database (Prisma over PostgreSQL). Every boundary has a
class-validator DTO, so malformed telephony payloads are rejected at the edge rather
than deep in a service.

My most sustained project at 68 commits. Daily reading plans for a church youth group, with reminders, confirmations, streak history and analytics for the leader. Polyglot by necessity rather than fashion: TypeScript, PHP, Python and shell all earn their place in the delivery path.
TypeScript PHP Python Shell
Notification platform in Arabic, Russian and English, built as a monorepo. Clergy send announcements, voice messages and live-stream alerts to the congregation.
The real constraint is not translation, it is direction: Arabic flips the layout, and the same components have to hold in right-to-left and left-to-right without a separate codebase. 22 commits, and the reason I will argue about bidirectional CSS.
Source is private at the parish's request, so there is no link here rather than a link that 404s. Happy to walk through the architecture.
TypeScript monorepo RTL
Cinematic bilingual site for a Moscow photo and print shop trading since 2010. Pure black voids with CMYK glow accents, a printer and press that morph through the hero, and a GSAP-pinned showcase that walks a sheet of paper through every production stage.

Counts show range, not weight. The single infrastructure project is the one I would put in front of an interviewer first.
Localisation is usually where a codebase's assumptions break. These shipped in more than one:
| Project | Languages | The hard part |
|---|---|---|
| Coptic Moscow private | Arabic · Russian · English | RTL and LTR sharing one component tree |
| sa-online-school | Arabic · English · Russian | Direction flip plus persisted theme and consent |
| astoria | Russian · English | Copy length changes breaking a pinned scroll animation |
| NodeMaven platform | English · Russian · Chinese | CJK metrics overflowing boxes tuned for Latin capitals |

I have shipped in more languages than this. These are the ones I would defend in an interview:
| Core | TypeScript · React · Node.js · Python |
| Frontend | Next.js · Vite · Tailwind · React Native / Expo · GSAP |
| Backend | NestJS · Flask · Express · Prisma · PostgreSQL · MongoDB |
| Platform | Docker · Linux · Nginx · GitHub Actions · WordPress |
Production work also in PHP, Java and C++, and comfortable in Bash and on Red Hat, but I would not claim those as current strengths.
- Measurement over assertion. If a tool makes a claim, the run behind it should be public.
- Documenting limits. The section listing what a tool cannot do is the one that earns trust.
- Quickstarts that actually run. A README whose first command fails costs more than a missing README.
