Досвід роботи

Full stack software engineer

з 04.2021 по 08.2025 (4 роки 5 місяців)
OSRAM, Remote (IT)

Stack used on the job: React, Next.js, TypeScript, Node.js (NestJS), Python/Django + DRF, Java/Spring Boot, SQL (PostgreSQL/MySQL), MongoDB, Redis, RabbitMQ, Docker, AWS (ECS/EKS, S3, CloudFront, RDS), CI/CD (GitHub Actions/Argo), React Native, Figma, REST/OpenAPI

- Owned end-to-end delivery of web features: collaborated in Figma, built UI in React/Next.js, exposed APIs in NestJS/Spring Boot, and shipped via CI/CD to AWS.
- Migrated a legacy PHP portal to Next.js + NestJS services backed by PostgreSQL and Redis. Server-side rendering and smart caching cut page load times and stabilized traffic spikes.
- Introduced a Django REST microservice for reporting and data quality. Celery workers handle nightly audits; results surface in Slack/webhooks for ops to act on.
- Split “orders” and “payments” into separate Spring Boot and NestJS services. Implemented idempotent consumers, DLQs, and retries on RabbitMQ to keep flows reliable under load.
- Set up Docker workflows and CI/CD (health checks, blue/green, one-click rollbacks). Releases moved from manual windows to routine deploys during working hours.
- Built a React Native companion app with offline-first sync (SQLite + queued background sync) for field technicians.
- Tuned data access (indexes, read replicas, connection pooling), moving heavy work to background jobs to keep p95 latency steady during promos and partner imports.
- Added observability: structured logs, metrics, and traces with clear runbooks, reducing guesswork during incidents.
- Mentored junior engineers; standardized DTOs, error handling, and API contracts so teams could work in parallel without friction.

Representative projects:
- Inventory & Availability: Next.js SSR + Redis caching + Postgres views for live stock and pricing; predictable cache invalidation.
- Billing & Invoicing: Spring Boot service for invoice lifecycle, PDF generation, and webhook notifications; full audit trail.
- Ops Admin: Django admin with granular permissions for safe data edits and content flags-no ad-hoc scripts.

Full stack software engineer

з 05.2018 по 03.2021 (2 роки 11 місяців)
RESCODE, Other countries (IT)

Stack used on the job: PHP (Laravel/Symfony), React, TypeScript, Node.js (NestJS), Python/Django, Nuxt.js (Vue), MySQL/PostgreSQL, MongoDB, Redis, RabbitMQ, Docker, Nginx, AWS, CI/CD (GitLab), REST/OpenAPI

- Built and maintained Laravel/Symfony APIs for authentication, billing, notifications, and reporting. Offloaded slow work to RabbitMQ workers and introduced Redis caching for read-heavy endpoints.
- Delivered a React dashboard with SSR and route-level caching; sign-in to first data felt instant and stayed consistent under load.
- Implemented a NestJS + Postgres reporting service with streaming CSV exports and webhook callbacks to avoid request timeouts.
- Spun up a lightweight Django admin for operations (content flags, safe edits, audit history) to reduce engineer interrupts.
- Containerized services with Docker and set up GitLab CI pipelines (lint → tests → build → deploy). Preview environments on each branch made reviews faster and safer.
- Built a partner portal in Nuxt.js for a Vue-leaning internal team while keeping the backend in Symfony with Swagger docs and consistent error contracts.
- Wrote small Python and SQL utilities for migrations/backfills when moving data between MySQL and Postgres.

Representative projects:
- Notifications Pipeline: Laravel → RabbitMQ workers with rate limiting and retries; reliable email/webhook delivery during spikes.
- File Imports: Node workers for CSV/Excel with schema validation and progress reporting back to the UI.
- Auth Refresh: Short-lived tokens + refresh flow with rotated secrets and tighter scopes.

з 08.2017 по 03.2018 (8 місяців)
Theranos, Remote (Medicine, pharmacy)

Stack used on the job: React, Node/Express, Python, PostgreSQL, Redis, REST, AWS

- Built an internal inventory/compliance dashboard (React + Express) with role-based access and audit logs.
- Created Python and SQL jobs for nightly reconciliation; removed manual spreadsheet steps and reduced data drift.
- Documented REST endpoints and added tests so QA and ops could automate checks without back-and-forth.
- Added simple Redis caching on read-heavy endpoints to keep the UI responsive.
