Security Hardening
OWASP best practices, SQL injection prevention, input sanitization, rate limiting, RBAC, and end-to-end encryption.
Microservices & Service Mesh
Domain-driven microservice decomposition with Istio, gRPC inter-service communication, and circuit breakers.
Event-Driven Architecture
Apache Kafka, RabbitMQ, and AWS SQS event streaming systems for decoupled, resilient asynchronous workflows.
Auth & Identity Management
OAuth 2.0, OIDC, SAML SSO, JWT, MFA, and role-based access control for enterprise-grade user authentication.
Observability & Monitoring
Distributed tracing with Jaeger/Zipkin, Prometheus metrics, Grafana dashboards, and PagerDuty alerting pipelines.
Data Pipelines & ETL
Scalable ETL pipelines using Apache Airflow, dbt, and Spark for data warehousing, analytics, and ML feature stores.

FAQ
Common questions
Monoliths are often the right choice for early-stage products — faster to build, easier to debug, and cheaper to run. We recommend microservices when you have clear service boundaries, distinct scaling requirements, or multiple teams. We can also help you modularize a monolith for gradual migration.
We have deep expertise in PostgreSQL, MySQL, MongoDB, Redis, DynamoDB, Cassandra, and ClickHouse. We help you choose the right database (or combination) based on your consistency, query, and scaling requirements.
We implement URL versioning (/v1/, /v2/), deprecation notices with sunset headers, and backward-compatible schema evolution. We never break your consumers — all changes go through a compatibility review process.
Yes — third-party integrations are a core competency. We regularly integrate with Salesforce, HubSpot, Stripe, Twilio, AWS services, SAP, and custom legacy systems via REST, GraphQL, webhooks, or message queues.
