How I Build
Practical engineering principles honed over 4+ years of shipping enterprise web software, maintaining production APIs, and decoupling business systems.
Component-Based Frontend
Modular state, reactive streams, and reusable UI boundaries
I structure client applications with strict separation between presentation and business logic. Utilizing Angular services and React/Next hooks, state flows predictably with minimum unnecessary re-renders.
- Modular components with clear input/output contracts
- Reactive streams (RxJS) for asynchronous telemetry and real-time feeds
- Defensive client-side validation paired with server error mapping
API-Driven Backend
Predictable REST endpoints, defensive contracts, and structured validation
Backend services should provide clear, predictable contracts. I build RESTful endpoints with Node.js and NestJS that enforce strong schema validation, clean middleware pipelines, and centralized error logging.
- Strict request payload validation via DTOs and schema checks
- Consistent HTTP status codes, structured error payloads, and audit logs
- Stateless session management with token verification and granular guards
Service-Oriented Architecture
Separating business capabilities without overcomplicating systems
When business requirements demand independent deployment or scaling, I break systems into focused microservices—such as isolating dialer engines from reporting services or separating reservation pipelines from billing.
- Clear domain boundaries around discrete business capabilities
- Asynchronous event decoupling using message queues (e.g. Kafka)
- Resilient failure handling and fallback states for inter-service communication
Data-Centric Systems
Relational integrity for transactions; document flexibility for dynamic data
I choose data persistence based on application needs: Microsoft SQL Server for ACID-compliant financial workflows, booking reservations, and relational ledgers; MongoDB for flexible call logs, form schemas, and dynamic documents.
- ACID transactional boundaries preventing double-allocations and ledger drift
- Type-safe database interactions with Prisma ORM and indexed SQL queries
- Flexible document schemas for high-frequency call logs and multi-step forms
