Online assessment
My experience with Artak was disappointing. He was not responsive during the contract and did not commit to the timeline we agreed upon before starting the project. The project, which was supposed to take 1–2 months, was delivered uncompleted after 8 months, and even then, it was incomplete and contained numerous bugs. This significant delay caused a financial impact on our side.
I strongly recommend ensuring clear milestones and deliverables before making any payments.
--> Do not release payment until you receive the project exactly as agreed and tested. <---

Most developers can build interfaces. Fewer can design correct models behind them. I do both.
With 15+ years of experience in web development and a PhD in Actuarial Mathematics and Statistics, I specialize in systems that involve calculations, data, and non-trivial logic — from financial tools to analytical platforms.
✔ What I deliver:
• Financial (annuities, investments, insurance models), statistical and other calculators
• Laravel / Yii2 / PHP applications
• Data analytics & reporting systems (dashboards, BI, statistics)
• API integrations and high-performance backend systems
• Mathematical and algorithmic solutions (probability, optimization, modeling)
✔ Why clients hire me:
• Rare combination: development + mathematics + business logic
• Ability to solve complex, non-standard problems
• Clean, maintainable, and scalable code
• Reliable communication and delivery
If your project involves complex logic, financial models, or data-heavy systems — I can help you build it correctly from the start.
Let’s discuss your project.
