Опыт работы

Full Stack JavaScript Developer

с 03.2020 по 03.2026 (6 лет)
Adversign Media GmbH, Дистанційно (IT)

Owned end-to-end development on a 12+ year-old Enterprise CRM platform serving B2B clients across 80+ countries (Europe, UK, US, Canada) — banks, airlines, large enterprises. Backend microservices, frontend modernization, Tech Lead on flagship initiatives. Agile/Scrum.

**Key Achievements:**

- **Monolith Decomposition** — Led decomposition of a Laravel monolith (~1,500 PHP files, 113 controllers, 800+ routes) into microservices. Designed the migration plan and personally implemented 3 core services end-to-end (Payment, Subscription, Zoho Integration). Enabled 3 developers to ship plugin microservices on the new foundation.
- **Payment Microservice (Stripe)** — Built a Node.js service handling Stripe subscriptions, SEPA, SWIFT, refunds, and webhook-driven processing across 80+ countries. All transactions flow via webhooks for guaranteed delivery and auditability.
- **Dynamic Subscription Microservice** — Architected a plugin-based system serving 30+ digital products. Evolved to a dynamic registry: new microservices register via API and auto-appear in subscriptions and Zoho (no code/DB changes). Supports hidden plugins (internal testing) and deprecated plugins (existing customers retain access while new activations are blocked).
- **Zoho CRM Migration** — Drove full migration from in-house PHP CRM modules to Zoho. Replaced custom invoicing, delivery/storage/search, lead/contact/company management. Reduced live API surface by ~50% (800+ → ~500 routes).
- **Event-Driven Communication (RabbitMQ)** — Designed inter-service messaging across 30+ microservices with production-grade patterns: idempotency, transactional outbox, retries with backoff, dead-letter queues.
- **On-Premise Enterprise Deployment** — Co-designed a self-hosted Docker deployment for high-security clients (banking) running isolated in their infrastructure. Built a stub-mode subscription emulator (JSON-driven manifest) — zero code forks between SaaS and on-premise.
- **Tech Lead — Template Builder & CRM Frontend** — Led a digital signage Template Builder rewrite (Canvas/AngularJS → HTML-native Vue.js) and the CRM AngularJS-to-Vue.js incremental migration.
- **Reusable Component Library** — Built a Vue.js library with Storybook docs, distributed via Git submodules.
- **AI Integration** — Integrated LLM features using LangChain and Hugging Face, including RAG pipelines with vector databases.
- **Testing & CI/CD (Tech Lead)** — Owned E2E testing strategy across CRM and microservices. Established Cypress (E2E, Visual, API) and Jest suites; designed a CI/CD pipeline with 4 parallel runs, fail-fast, and retry logic for flaky-test isolation.
- **Custom Web Components** — Built framework-agnostic components with Stencil.js, reusable across Vue.js, AngularJS, and React.

**Tech Stack:** Vue.js, React, AngularJS, Stencil.js, Node.js, Nest.js, TypeScript, MongoDB, RabbitMQ, GraphQL, REST, Stripe, Zoho CRM, Docker, Kubernetes, AWS, LangChain
