Think in systems, build with care, ship things that last.

Hi, I'm Amirhossein

Senior Backend EngineerPHP/Laravel & Python/Django/FastAPI

Yerevan, Armenia
9+ Years Experience

I'm a senior backend engineer with eight years building systems that handle real money, real scale, and real consequences: e-commerce platforms, payment and billing systems, ERP integrations, and the modernization of legacy systems that had stopped keeping up.

I've cut a platform's infrastructure cost by an order of magnitude by rebuilding it properly, traced production bugs that were quietly losing money, designed fault-tolerant services that stay correct when things fail, and led teams of engineers doing the same.

Production benchmarks
400K+
Pages Crawled Daily

Optimized Python Celery crawler with 40% CPU and 50% memory reduction.

0
Duplicate Refunds & Payouts

Redesigned the payment flow to eliminate double transfers and the errors that came with them.

92%
Infrastructure Saving

Rebuilt a legacy platform off Azure, from ~$2,000/mo to ~$160/mo on a single instance.

4,000+
ERP Integration Events

Asynchronous outbox-pattern system running on a single Kubernetes pod.

Linrova

One personal assistant for the tools that usually live across separate apps.

Linrova replaces a drawer full of disconnected apps with one workspace: capture a thought in seconds, then turn it into a flashcard, a habit, or a reminder without breaking focus. Six tools are live today, with a planner, todo lists, meal planning, and shopping lists next. I co-created it with my wife and lead most of the product and engineering work: a Laravel API, a React PWA localized into 8 languages including right-to-left, Python services for embeddings and asynchronous jobs, and the deployment and monitoring behind them.

Product journey

Brain Dump

Sub-five-second capture into a single stream, with entries convertible into flashcards later.

Flashcards

Basic, reversed, type-in, and cloze cards on a spaced-repetition scheduler that queues each review.

Balance Sheets

Separate personal, family, and business sheets of assets and liabilities, with net worth recalculated as entries change.

Loan Comparison

Offers compared side by side on true total cost rather than headline rate, saved for later review.

Habit Tracking

Daily, weekly, and monthly schedules with streaks, completion stats, and habits shared between accounts.

Reminders

Recurring nudges on interval or fixed-day schedules, grouped into lists and tags and cleared in batches.

Recall

Planned

Notes, links, and images stored as embeddings, then retrieved by meaning through semantic search.
