SENIOR PHP · LARAVEL · ARCHITECT · INTEGRATOR

I design and ship serious systems.

10+ years in development, 8+ at architecture level. Large REST APIs, hard integrations, realtime, AI in production — from architecture to a deployed service. I design it, write it and ship it myself, at production quality.

Ask my AI about me

A live assistant grounded in my real experience. Ask anything — payment integrations, realtime, whether I can architect and ship a product end to end. Straight answers, no fluff.

Answered by Claude on request (a consent prompt appears on the first question). If the assistant is unavailable, all projects and experience are on the page below.

Flagship: Hospitality SaaS (BG)

Hospitality SaaS for hotels and chains: channel manager, direct-booking engine, PMS, rates and availability, billing with fiscalization, CRM with AI. My main commercial project — architecture and integrations.

PHP 8.4 · LARAVEL 13 · DDD

A hotel platform built the grown-up way

Strict four-layer DDD: thin controllers → use-cases → domain entities and repository interfaces → infrastructure. A hand-designed REST API across three surfaces (SPA/Sanctum, partner OAuth2 “Hospitality SaaS (BG) Connect”, B2B/PMS), with refresh-token rotation, rate-limiting, idempotency and HMAC-signed webhooks.

Own products — idea to production

Full cycle solo: architecture, backend, frontend, realtime and infrastructure — down to a service running on the internet. Different stacks and domains, all taken to production quality. Modern tools (AI included) for speed; the decisions and quality are mine.

The stack I ship a project with

Architecture, backend, markup, frontend, realtime, data, integrations, AI and DevOps — I take a project all the way to a working service, not just to code in a repo.

Let’s talk about your project

Working remotely (EET/EEST, Bulgaria). I’ll architect a system, untangle a hard integration, embed AI, or build a product from scratch and ship it.

⏰ I take on projects in my off-hours — after 18:00 or before 09:00 (Bulgaria, EET/EEST). I have a main job I genuinely love and am fully committed to: I value loyalty and won’t let my main employer down for a temporary project. But evenings and early mornings — I’m fully in, on call, and shipping.
