Backend & Infrastructure
Engineering

I design and build production-grade server-side systems from the ground up — architecture, databases, microservices, cloud infrastructure, CI/CD, monitoring, and everything in between.

Services

Specialised in backend engineering and infrastructure — I cover everything from application architecture to production deployment and operations.

API
Backend & API Development

Design and implementation of robust, secure server-side applications. RESTful APIs, microservices architecture, database design, authentication, message queues, and event-driven systems built to scale.

Node.js JavaScript C# REST API RabbitMQ MongoDB MySQL Redis Elasticsearch
OPS
Infrastructure & DevOps

Full infrastructure setup from scratch — servers, networking, containerisation, Kubernetes clusters, CI/CD pipelines, automated deployments, and GitOps. Everything described as code, reproducible and version-controlled.

MON
Monitoring & Observability

Setting up comprehensive monitoring, logging, and alerting so you always know the health of your systems. From metrics collection to dashboards and on-call alerts — before your users notice a problem.

Grafana Alloy Alerting Log aggregation Dashboards
ARC
Architecture & System Design

End-to-end system design for new projects: technology selection, database schema, microservice boundaries, inter-service contracts, security model, and infrastructure planning — before a single line of code is written.

Microservices IaC Database design Security Scalability DNS & networking
INT
Integrations & Automation

Connecting your systems to third-party services via webhooks and APIs. IP telephony, SMS providers, Telegram bots, payment gateways, CRM integrations — and custom automation pipelines that eliminate manual work.

Working process

A straightforward flow designed to minimise back-and-forth and maximise the quality of what gets built.

01 / Discovery
Understand your needs

We start with a free 30-minute call to clarify goals, constraints, and timeline. No commitment required at this stage.

02 / Proposal
Scope & estimate

I send a written proposal with detailed scope, deliverables, timeline, and fixed price or rate. You review and approve.

03 / Build
Development

Work begins. You have visibility into progress via shared task board and regular updates. Feedback loops are short.

04 / Delivery
Handover & support

Final deliverables are handed over with documentation. Post-delivery support is included in all project engagements.

About me

I'm Ivan Anisimov, a backend and infrastructure engineer with over 10 years of experience. My core strength is taking a project from zero — designing the architecture, setting up the full infrastructure as code, and writing the backend — through to a running production system.

I've built CRMs, sales management systems, parsers, aggregators, and data-intensive platforms. I set up complete infrastructure end-to-end: DNS configuration, server provisioning on bare metal or cloud (GCP), Kubernetes clusters, automated GitLab CI/CD pipelines with ArgoCD, monitoring and alerting with Grafana. Everything written in IaC — reproducible, version-controlled, maintainable.

I have basic frontend knowledge and can put together simple interfaces when needed, but backend and infrastructure is where I specialise and where I deliver the most value. All work is done personally by me, project-based, with clear scope agreed upfront.
