🥇 Expert in Symfony, Laravel and PHP, they're my bread and butter. Over 10 years I've built and shipped 30+ Symfony applications - from high-traffic SaaS platforms and complex REST API ecosystems to enterprise admin panels handling millions of requests daily. I also build and customize Shopware 6 and Sylius e-commerce platforms, both built on Symfony at their core - custom plugins, API integrations, and storefront modifications. If your project runs on Symfony, Shopware, or Sylius, you're talking to someone who thinks in Bundles, Services, and Doctrine entities. I'm equally deep in Laravel. I've delivered 50+ Laravel projects including multi-tenant SaaS apps, REST API backends, payment integrations (Stripe, PayPal), and real-time dashboards with Laravel Echo and WebSockets. From Eloquent to Queues to Nova admin panels - I know the framework inside out. At the core of everything I do is PHP. With 88+ projects delivered on Upwork alone, I write clean, tested, production-grade PHP that follows SOLID principles, PSR standards, and modern PHP 8.x features (enums, fibers, named arguments, attributes). I've also worked extensively with Yii2 for legacy projects and migrations to modern frameworks. Beyond PHP, I'm comfortable building microservices and background workers in Node.js and Python. I also leverage AI-assisted development tools - GitHub Copilot, Claude, and ChatGPT - to accelerate code generation, debugging, and code review, delivering faster without compromising quality. 𝗪𝗛𝗔𝗧 𝗜 𝗗𝗘𝗟𝗜𝗩𝗘𝗥 ▸ Symfony, Shopware 6 & Sylius - Doctrine ORM, Twig, API Platform, Messenger, e-commerce plugins, storefront customization ▸ Symfony Core - Flex, Panther E2E testing, Messenger queues, Security component ▸ Laravel - Eloquent, Blade, Nova, Horizon, Sanctum/Passport, Laravel Vapor ▸ APIs - RESTful API design, GraphQL, SOAP, third-party integrations (Stripe, Twilio, AWS SDK) ▸ Cloud & DevOps - Docker, Amazon Web Services (EC2, S3, RDS, Lambda), CI/CD with GitHub Actions & Jenkins ▸ Testing - PHPUnit, Pest, Symfony Panther, Selenium, 80%+ code coverage as standard ▸ Frontend - React, Vue.js, Livewire when full-stack delivery is needed ▸ Backend - Node.js services, Python scripting & automation, Yii2 maintenance ▸ Databases - MySQL, PostgreSQL, MongoDB, Redis caching & queue management ▸ AI-Assisted Dev - GitHub Copilot, Claude (Opus/Sonnet), ChatGPT, Cursor for accelerated workflows 𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞 I don't just write code - I architect solutions. Every project starts with understanding your business goals, then I design a clean, scalable architecture before writing a single line. I deploy to Amazon Web Services with Docker containers and automated CI/CD pipelines. I communicate daily, ship incremental PRs, and write tests alongside features so nothing breaks in production. 𝗥𝗘𝗦𝗨𝗟𝗧𝗦 → 88+ Upwork projects delivered successfully → Built Symfony REST API backends serving 2M+ requests/day → Reduced Laravel app response times by 60% through query optimization & Redis caching → Migrated legacy Yii2 and PHP codebases to modern Symfony 6/Laravel 10 with zero downtime → 100% Job Success Score track record Available for immediate start. Whether you need a Symfony application built from scratch, a Laravel API scaled for growth, or a legacy PHP codebase modernized - let's talk. Message me with your project details and I'll respond within 2 hours with a clear plan.

I help engineering teams and technical founders make the right system decisions before they become expensive — scoping what to build, de-risking architecture before irreversible choices are made, and owning delivery through to scale. My background spans cloud architecture, solution architecture, and database systems across AWS and Azure. The combination matters: most production failures I have seen trace back not to bad code, but to structural decisions made early in the schema, the system boundaries, or the deployment model — that compounded quietly until they could not be undone. I am based in Armenia and work async-first with clients across the US, Europe, and Australia. Architecture work — system design, technical reviews, decision documentation, governance frameworks — does not require timezone overlap. My clients do not experience geographic friction. 🔹 𝐓𝐡𝐫𝐞𝐞 𝐫𝐞𝐜𝐞𝐧𝐭 𝐩𝐫𝐨𝐣𝐞𝐜𝐭𝐬 𝐭𝐡𝐚𝐭 𝐜𝐚𝐩𝐭𝐮𝐫𝐞 𝐡𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤: 𝐆𝐃𝐂 𝐌𝐞𝐝𝐢𝐚 (𝐈𝐫𝐞𝐥𝐚𝐧𝐝) — built an LLM-assisted database audit engine running across 3 MySQL clusters and 15 production nodes. 13 independent checkers feed findings to the LLM, which grades each as Critical / Major / Minor / Trivial and writes a short, grounded explanation. Runs hands-off 365 times a year. 𝐇𝐑𝐒 𝐆𝐫𝐨𝐮𝐩 (𝐂𝐨𝐥𝐨𝐠𝐧𝐞, 𝐆𝐞𝐫𝐦𝐚𝐧𝐲) — designed and built financial data pipelines on AWS that bridge MS Navision (ERP) and SAP through a single canonical model. Safe to replay, with scheduled reconciliation. 𝐆𝐥𝐚𝐬𝐬𝐰𝐚𝐥𝐥 𝐒𝐨𝐥𝐮𝐭𝐢𝐨𝐧𝐬 (𝐔𝐊) — Cloud Engineer on the Content Disarm and Reconstruction platform now trusted by NATO and U.S. and U.K. national security agencies. Helped adapt the platform for AWS EKS, Azure AKS, and K3s, and built the file ingress orchestration plugin handling terabytes of potentially infected files. 🧭 𝐇𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤 I don't approach projects as feature delivery. I approach them as temporary or ongoing technical ownership — short engagements that clarify direction, longer ones that carry the system through to scale. The shape is the same in both: • Reduce MVP scope while keeping the core value loop intact • Define cloud architecture and system constraints before implementation begins • Make decisions explicit instead of accumulating quiet assumptions • Separate short-term delivery from long-term structural risk • Hand off to in-house engineers cleanly when the moment is right Some engagements take two weeks. Some turn into multi-year work. The goal in both is the same — systems that don't need heroics to keep running. 🎯 𝐖𝐡𝐞𝐫𝐞 𝐩𝐫𝐨𝐣𝐞𝐜𝐭𝐬 𝐮𝐬𝐮𝐚𝐥𝐥𝐲 𝐠𝐞𝐭 𝐬𝐭𝐮𝐜𝐤 In early- and growth-stage systems, the biggest problems are rarely about tooling or raw engineering skill. They are decision gaps: • Feature lists that grow faster than clarity • AI is treated as a black box instead of a constrained system • Developers hired before the success criteria are defined • Architectural decisions deferred until they're expensive to reverse • "We'll fix it later" choices that quietly become permanent That's the layer I focus on stabilizing first — so execution stays fast without becoming brittle. ⛁ 𝐃𝐚𝐭𝐚𝐛𝐚𝐬𝐞 𝐚𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞 & 𝐝𝐢𝐚𝐠𝐧𝐨𝐬𝐭𝐢𝐜𝐬 Production databases are where architectural decisions surface most visibly — slow queries, bloated indexes, configuration drift, schema choices that worked at 10K rows and break at 10M. I have extensive hands-on experience with PostgreSQL, MySQL, and MariaDB in high-load production environments. For teams that need a fast, structured assessment: I offer a fixed-price SQL database audit via my Project Catalog — a prioritized diagnostic report delivered in 1–2 days, ranked by business impact. 🧱 𝐒𝐭𝐚𝐜𝐤 • Databases — PostgreSQL, MySQL, MariaDB, OpenSearch, Elasticsearch, DynamoDB • Cloud — AWS, Azure, Kubernetes, Docker, serverless • Security — IAM, encryption, access boundaries, secure data flows • DevOps — CI/CD, GitHub actions, CloudFormation, observability • AI-adjacent — guardrails, confidence gating, deterministic vs. generative boundaries Technology serves decisions, not the other way around. 📅 𝐄𝐧𝐠𝐚𝐠𝐞𝐦𝐞𝐧𝐭 𝐟𝐨𝐫𝐦𝐚𝐭𝐬 • Long-term architecture and delivery ownership • Fractional CTO or technical advisor • Short-term advisory (1–4 weeks) • Fixed-price SQL database audit (Project Catalog — from $750) Most successful collaborations start small and grow naturally once alignment is in place. 📨 𝐋𝐞𝐭'𝐬 𝐭𝐚𝐥𝐤 If you are unsure what to build, what to cut, or how to de-risk a critical phase — or if your database is showing signs of trouble — a short conversation usually makes sense. From there, we decide together on the right shape of engagement.
