Artiom Startev

Technical responsibilities:

• Core API & Business Logic:
- Design and implement complex, large-scale business logic in Go (Golang) powering the central and high-throughput API serving as the primary aggregation layer for flight and transportation data.
- Build and maintain a large, well-structured set of REST routes using Gorilla Mux, enforcing clean separation of concerns and maintainability across a rapidly evolving codebase.

• GDS Integration & Microservices Architecture:
- Integrate with multiple GDS (Global Distribution System) providers, orchestrating data retrieval, normalization, and transformation into a unified internal format aligned with business rules.
- Architect and develop dedicated GDS-specific microservices (Go) using frameworks such as Fiber and Gin, each encapsulating the integration logic for a single GDS and exposing clean internal APIs consumed by the central API.

• Concurrency & Performance Engineering:
- Leverage Go's concurrency primitives — goroutines, channels, semaphores, worker pools, fan-out/fan-in patterns — to maximize throughput and minimize latency across parallel GDS calls and data processing pipelines.
- Author unit tests, benchmarks, and performance tests to enforce correctness and efficiency standards at the component and system level.

• Caching & Data Flow:
- Integrate Redis for distributed caching of frequently accessed GDS responses and computed results, reducing redundant external calls and improving response times.
- Publish processed results and domain events to Kafka topics, enabling downstream departments and services to consume real-time flight and transportation data asynchronously.

• Observability & Infrastructure:
- Implement structured logging with the ELK Stack (Elasticsearch, Logstash, Kibana), configuring appropriate log levels per environment (dev, staging, production) for efficient debugging and audit trails.
- Instrument services with Prometheus metrics and build Grafana dashboards for real-time visibility into system health, latency, throughput, and error rates.
- Manage build and deployment pipelines through Jenkins, coordinating continuous integration and delivery across multiple Go services.

Technical responsibilities:

Frontend:

- Build complex SPAs with Angular + TypeScript + RxJS, SCSS and Bootstrap.
- Implement modular, OOP-style components, advanced reactive forms (custom validators) and dynamic, data-driven UIs.
- Integrate with AWS AppSync (GraphQL); host static assets in S3 and distribute via CloudFront (OAI).
- Maintain unit tests with Jest and enforce high code quality.

Backend:

- Develop services in Go (Golang) using goroutines, channels and concurrency patterns for performance.
- Integrate with third-party systems (e.g., AFAS) and persist data in Aurora Serverless (MySQL) via GORM.
- Expose APIs through AppSync (GraphQL) and API Gateway (REST).

Serverless & Async Workflows:

- Build Lambda-based microservices (Go) invoked by AppSync pipeline resolvers or API Gateway.
- Implement resilient async processing using SNS → SQS → Lambda.

Infrastructure as Code:

- Design and manage the AWS estate with AWS CDK (TypeScript).
- Manage stacks, nested stacks and environment deployments.

CI/CD, Security & Observability:

- Build and run pipelines (CodeBuild / CodePipeline) and deployment scripts (Bash).
- Configure authentication/authorization with Cognito (user pools/groups/custom attributes).
- Implement centralized logging, tracing (X-Ray) and WAF protection; secure secrets with Parameter Store / Secrets Manager.

Testing, Reviews & Enablement:

- Cypress E2E automation and CI integration; collaborate with QA to reduce flakiness.
- Review all FE/BE PRs, mentor teammates, produce docs to accelerate onboarding and maintain standards.

Process & collaboration:

- Actively participate in refinement, sprint planning, retrospectives and architecture reviews.
- Translate business needs into technical requirements and prioritize trade-offs with stakeholders.
- Make deployment, rollback and incident decisions as the reliable owner for on-call and production activities.
