You will get a backend performance audit with actionable optimization recommendations
Project details
I help backend teams find and fix the real causes of slow APIs, slow database queries, and laggy admin panels. I've optimized systems handling high-traffic e-commerce checkouts, real-time IoT data pipelines, and content-heavy admin dashboards - tracking down N+1 queries, missing indexes, unnecessary API calls, and inefficient caching.
You'll get a clear breakdown of what's slowing your system down, ranked by impact, plus hands-on fixes: query optimization, Redis caching, connection pooling, and code-level changes where needed. I'll also set up basic monitoring so you can track improvements and catch regressions.
Send me access to your repo (or a representative sample) and I'll start digging in.

About Irakli
Backend Engineer | Node.js/TypeScript | Payments & Real-Time Systems
Tbilisi, Georgia - 9:19 am local time
Recent work: integrated Stripe, BTC Pay Server, PassimPay, and Cryptomus into a platform serving roughly 10,000 customers, handling subscriptions, one-time charges, and invoices end-to-end. I also built a notification service delivering real-time alerts across email, SMS, Telegram, and websockets, plus a job-scheduling pipeline driven by MongoDB change streams with BullMQ.
In healthcare, I built clinical REST APIs with role-based access control and full audit logging for a system live across multiple clinics. In insurance, I integrated bank payment APIs and unified several third-party insurer APIs behind one consistent interface. I've also optimized slow database queries (cut one response time from 6-7 seconds to under 2 seconds) and led a migration from Express to NestJS to make a growing codebase easier to maintain.
Stack: Node.js, TypeScript, NestJS, Express.js, PostgreSQL, MySQL, MongoDB, Redis, RabbitMQ, AWS, Docker, GraphQL, Socket. IO.
I work across the full Node.js/TypeScript backend: APIs, integrations, databases, background jobs, real-time features, and payment systems. I reply fast and communicate clearly throughout.
