You will get a reliable notification system that prevents costly downtime
Project details
Notification delivery is often a critical part of your business workflow. Whether you send OTP codes, payment confirmations, order updates, security alerts, or marketing messages, delayed or lost notifications can lead to failed transactions, frustrated users, customer churn, and lost revenue.
I will design and implement a scalable notification platform that ensures your messages are delivered reliably, even during traffic spikes, infrastructure failures, and periods of rapid business growth.
The solution can support multiple delivery channels, including Email, SMS, Push Notifications, WhatsApp, Telegram, and In-App Notifications, while providing a unified API for seamless integration into your existing systems.
Your notification platform will be built with reliability and operational visibility in mind. Depending on the selected package, the system may include fault-tolerant architecture, automatic horizontal and vertical scaling, multi-cluster Kubernetes deployment, retry mechanisms, delivery tracking, monitoring dashboards, and real-time analytics.

About Aleksei
Backend Engineer | Scalable Systems | APIs | Performance & Scaling
Batumi, Georgia - 8:30 am local time
If your API is slow, your system doesn’t scale, or your backend is becoming hard to maintain — I can help you identify the problem and implement a solution that actually works in production.
I focus on practical results, not overengineering.
What I typically work on:
• Building backend systems from scratch (fast MVP → scalable production)
• Fixing performance issues (slow APIs, high latency, bottlenecks)
• Designing clean and scalable system architecture
• Refactoring messy or hard-to-maintain codebases
• Setting up microservices and event-driven systems
• Integrating payments, auth, and third-party APIs
• Improving database performance and query efficiency
I work primarily with Go (Golang), and I also use Python and Java when needed — especially for integrations or working with existing systems.
My approach is simple:
- understand the real problem (not just symptoms)
- propose a solution that fits your stage (not overkill)
- deliver something stable, maintainable, and production-ready
Tech I use regularly:
Go, PostgreSQL, Redis, Kafka, RabbitMQ
REST API, gRPC, API integrations
Docker, Kubernetes, AWS, CI/CD
I’m comfortable working on:
high-load systems, distributed systems, microservices, and performance optimization.
I communicate clearly, ask the right questions, and don’t disappear in the middle of the project.
If you need someone who can think through your backend and not just write code — feel free to reach out.
