For Employers

Artur Tsarikovich Senior Backend & AI Engineer

Backend engineer with a strong record in scalable systems, cloud-native architecture, ML infrastructure, and production-grade delivery.

Best fit for roles where backend depth, reliability, ownership, performance, and practical AI experience all matter at the same time.

Senior Backend Engineer Platform / Infrastructure Applied AI / ML Systems

Core strengths

Why hiring teams tend to trust my profile

Systems thinking

I design backend systems from the operational level up: data flow, failure modes, throughput constraints, observability, and maintainability.

Applied AI without hype

I focus on production usefulness: inference pipelines, vector search, evaluation, lifecycle automation, and measurable cost control.

Performance and reliability

Async processing, multiprocessing, data pipeline optimization, and release workflows that reduce operational friction.

Ownership and clarity

I communicate clearly, document decisions, mentor where useful, and care about the long-term shape of the system, not just the next patch.

Role fit

Where I tend to create the most value

Backend

Senior Backend Engineer

For teams that need high-quality implementation with architecture awareness, clean code, and production accountability.

Platform

Platform / Infrastructure Engineer

For systems where reliability, deployment flow, data movement, observability, and operational maturity matter as much as features.

Applied AI

AI Infrastructure / Applied AI Engineer

For products that need practical AI with evaluation, orchestration, vector search, cost awareness, and a clean production path.

Selected impact

Practical outcomes, not just tool familiarity

45%

Cost optimization

Cut Bedrock usage costs through prompt caching and evaluation improvements while maintaining quality.

6x

Throughput increase

Increased workload throughput through async and multiprocessing orchestration on data-heavy pipelines.

70%

Pipeline reliability gain

Automated ML lifecycle flows to remove manual intervention and improve delivery consistency.

99.9%

Stable platform delivery

Delivered APIs, releases, and processing systems that remained dependable under production pressure.

Experience

Relevant experience in production environments

Architecture showcases

Representative systems I can own from design to production

Applied AI

Inference, evaluation, retraining, and vector search pipeline

End-to-end flow from extraction and embeddings to index updates, relevance logic, evaluation loops, and production monitoring.

Data platform

Event-driven ingestion and processing backbone

High-volume ingestion, async orchestration, retry-safe processing, storage design, and observability-first operations on AWS.

Execution systems

Low-latency decision and execution backend

Real-time backend logic with monitoring, storage strategy, execution safety, and throughput control under live conditions.

Stack and domains

Comfortable at the intersection of backend, cloud, and applied AI

Core technologies

Python AWS FastAPI Flask PostgreSQL Redis Docker Kubernetes OpenSearch Prometheus

Best used on teams that need

  • Strong backend implementation with architecture awareness
  • Someone who can navigate both infrastructure and product constraints
  • A disciplined engineer who cares about clarity and long-term quality

Hiring

If you need backend depth with real production judgment

I’m open to conversations around backend, infrastructure, platform, and applied AI roles where technical quality and business impact both matter. Relevant project scope, ownership, and execution context can be shared during the process.
