I build the systems your product runs on.
Databases, payments, logins, admin tools, the server that has to stay up. I design it, build it, and I'm the one who answers when something breaks. Five years doing this inside European engineering teams, and more recently, on my own.
Three production platforms, all built solo, all monitored by me around the clock with a dashboard I built myself.
A math degree, then five years of production code.
I studied mathematics and computational analysis at Lomonosov Moscow State University, then spent the years since turning that into working software. I started by scraping and structuring real-world data, then moved into building the FastAPI and Django backends that products actually run on: the part that stores your data, handles your traffic, and has to be right the first time.
I've done that work inside teams, most notably at Realtify and PriceHubble, where a Czech real-estate technology company I joined in 2020 was acquired by its Swiss parent the following year, and I stayed on to build the FastAPI services routing live traffic to their machine-learning models. I've also done it completely alone, taking three platforms from an empty repository to real users with no one else touching the code.
Either way, the job is the same. Understand what the business actually needs, build it properly, and be the person who picks up the phone when something breaks.
What I actually build for you
No jargon. Just what each of these means for your business.
A full platform, from scratch
Give me an idea and I'll build the backend underneath it: the database, the API, user accounts, and the admin screens your team needs to run things day to day.
Online stores and payments
Secure checkout, order tracking, stock that stays accurate under real traffic, and Stripe set up properly the first time.
Admin tools your team can use
So nobody has to call me every time a price needs changing or an article needs publishing.
Performance that holds up
Search and filtering that stay fast as your catalog or user base grows, instead of slowing down under their own data.
Monitoring, so you hear about problems first
I put dashboards and uptime checks on everything I build and get an alert the moment something is wrong, usually before a customer notices.
Fixes and migrations
Inherited a fragile or slow backend? I can untangle it, move it to a better database, or rebuild the parts that keep breaking.
Three platforms I built end to end
Each one designed, built, deployed, and still maintained by me alone.
ShopLux, a multi-vendor luxury fashion marketplace
The challenge: give several luxury fashion brands a single online storefront where they can list products, take real payments, and publish their own editorial content, without needing a developer for every update.
What I built: solo, from the database structure up. Secure checkout with Stripe, stock that updates safely even when several orders land at once, a customer account area, and a Journal and News section the brand can publish to itself. I also built the monitoring dashboards that tell me if anything on the site slows down or breaks.
A cultural events aggregator
The challenge: bring exhibitions, cultural events, and discounts from many different sources into a single place, kept up to date without anyone entering it by hand.
What I built: the full backend and a REST and GraphQL API built to serve both the website and other apps, an admin panel non-technical editors can actually use, and automated pipelines that pull in and clean event data from around the web.
A directory of verified charitable organizations
The challenge: help people find and trust Armenian charitable organizations, backed by accurate information the charities' own staff can keep up to date themselves.
What I built: a Django backend with admin tools designed for non-technical staff, location and mapping so people can find organizations near them, and a full visual redesign I led from the ground up.
How I got here
Five years, one straight line from data to full production systems.
DataNerds
Started in data: scraping and analyzing real-world datasets, and learning to turn messy information into something usable.
Realtify, Czech Republic
First production backend role, building real-estate data pipelines feeding a live product.
PriceHubble, Switzerland
Realtify's Swiss parent company after its 2021 acquisition. Built and maintained the FastAPI microservices routing live traffic to machine-learning models, and led the migration from Flask to FastAPI.
PM Solution
Full stack engineer, building custom accounting and business-management applications in Django and Angular.
South Gate Armenia
Contract backend engineer, working in Django alongside a React frontend team.
Independent
Designed and built the Culture Aggregator and Baregorc from an empty repository to production, alongside a contract stretch at DataHatch.
ShopLux
Building a full multi-vendor e-commerce platform, solo, end to end.
Why work with me
I'm based in Porto, Portugal, with full legal authorization to work anywhere in the EU. There's no agency and no account manager between us. You talk directly to the person who designs the system and writes the code, and I stay involved after launch instead of disappearing once it ships.
I also run my own uptime monitor, a small dashboard I built myself that watches every platform I maintain around the clock. It's the same habit I'd bring to your project.
- EU work authorizedBased in Porto, ready to work with clients across Europe.
- Direct communicationFluent English, plus Armenian and Russian as native languages.
- Full ownershipArchitecture, build, deployment, and monitoring, handled by one person.
- Still growing local rootsCurrently learning Portuguese, on top of the languages above.

He's a great team player, always ready to help others and respectful of everyone.
ColleagueWe worked at PriceHubble very closely. He was my buddy at work when I started, very helpful and friendly. He has an eye for detail, does thorough end-to-end testing, and has strong backend and analytical skills. He also learned frontend in a very short time and contributed in a timely manner.
Colleague, PriceHubbleAyk is a nice and easy-going person. During our work he was a great contributor to the application, its features, architecture, and technical documentation. He ran knowledge-transfer sessions for newcomers, was always willing to help, and has a strong technical background and great soft skills.
ColleagueHe did a great job improving and maintaining our FastAPI services, carefully adding new functionality without breaking existing behavior. I especially want to highlight his work migrating and normalizing data from Azure Cosmos DB into PostgreSQL and MongoDB, a process that was smooth and reliable. A very dependable backend engineer and an easy person to work with.
Freelance clientAyk played an important role in developing and maintaining our FastAPI services, consistently introducing new features while keeping existing functionality stable. He led the migration and normalization of data from Azure Cosmos DB into PostgreSQL and MongoDB, handled smoothly from start to finish. A reliable, thoughtful engineer and a pleasure to work with.
