Досвід роботи

Python Developer | Tech Lead

з 09.2025 по нині (1 рік 3 місяці)
Admiral Studios, Дистанційно (IT)

Professional networking & freelance marketplace — Django, DRF, PostgreSQL, Elasticsearch, Redis, Celery, WebSockets, OpenAI API, AWS
• Joined a 3-year-old codebase, analyzed its architecture and implemented multi-profile accounts (employer and talent) with active-profile request scoping.
• Built Elasticsearch global search across 8 entity types with RBAC/ABAC permission enforcement. Replaced 7 endpoints (2–3 s on dev) with one flexible API, reducing response time to 100–300 ms.
• Developed personalized recommendations, WebSocket chat and LLM-generated profile descriptions.
• Implemented AI moderation using OpenAI Moderation for text and AWS Rekognition via Lambda for images and videos.
• Interviewed, onboarded and mentored a developer; delegated tasks and reviewed PRs.

Automated investing app (fintech) — Technical Lead, built from scratch — FastAPI, SQLAlchemy, PostgreSQL, Celery, RabbitMQ, Redis, Plaid, Alpaca, Stripe
• Researched competitors, evaluated Plaid and Alpaca APIs, prepared technical specifications, estimates and milestones.
• Designed backend architecture, database schema, service/repository layers, authentication, authorization and async infrastructure.
• Implemented Plaid transaction sync, investment calculations, scheduled Alpaca investments, notifications and SSE updates.
• Hardened financial workflows with retries, reconciliation, idempotency and consistency checks to prevent lost or duplicated transactions; fixed security vulnerabilities.
• Mentored a developer and continued supporting him after transitioning to another project.

Family diabetes-care app (healthtech) — SQLAlchemy, PostgreSQL, Redis, RevenueCat
• Developed backend features for family diabetes management, including medical records, caregiver notes and child status updates.
• Fixed critical database performance issues: disabled implicit lazy loading (raise_on_sql), eliminated duplicate queries, reused request-scoped sessions and added Redis caching. Reduced response time from ~10 s to 20–50 ms.
• Designed RBAC/ABAC permissions, audit trails and family-based premium access.

Internal knowledge assistant (RAG) — Python, pgvector, OpenAI API, Confluence, Google Sheets, Telegram Bot API
• Built a RAG assistant with automatic Confluence sync, embeddings, semantic retrieval and document-grounded answers with explicit fallback.
• Delivered Telegram bot and web UI with Google Sheets-managed access control and admin commands for synchronization and re-embedding.

Pre-sales & engineering
• Analyzed client requirements, assessed feasibility, prepared estimates, refined specifications and supported delivered projects.
• Built an AI code-review skill for Claude Code, evaluated findings and false positives, and used AI-assisted development with manual review.
