maintainability.
Define service boundaries, data ownership, and communication patterns.
Select and apply appropriate architecture patterns such as:
Modular monoliths
Microservices
Event-driven systems
Layered and hexagonal architectures

Indexing
Query optimization
Transactions and isolation levels
Design data models for NoSQL systems (MongoDB, DynamoDB, Redis, etc.).
Select the right data store based on access patterns and consistency needs.
Handle database migrations, versioning, and backward compatibility.
Distributed Systems

Partial failures
Retries, timeouts, and idempotency
Horizontal scaling
Work with message brokers and async communication such as:
Kafka
RabbitMQ
AWS SQS

Understand Kubernetes concepts (pods, services, autoscaling).
Collaborate with DevOps/SRE teams on observability, logging, and monitoring.
Technical Leadership
Act as technical owner for backend systems.
Mentor senior and mid-level engineers.
Define engineering standards and best practices.
Work closely with product and business stakeholders to translate requirements into
technical designs.
PRIMARY SKILLS
 10+ years of backend/software engineering experience.
 3+ years of production experience with FastAPI.
 Expert-level Python knowledge.
Strong experience with:

 At least one NoSQL datastore
Deep understanding of:
 Backend architecture patterns
 Design patterns (GoF, SOLID, DDD concepts)
 Distributed systems fundamentals
 Experience designing and evolving large-scale systems.
 Hands-on experience with cloud services and deployments.
 Proven ability to lead architecture decisions and technical discussions.
