Engineering capabilities — what I design and ship

client → gateway → services

⬡ Click a domain to explore the technical depth behind it.

Capability · Auth

Authentication & Authorization

JWT, sessions, RBAC, and multi-tenant isolation — the trust layer every downstream service depends on. Built to be the single authoritative gate for any platform.

JWTRBACSessionsOAuth2Middleware

Clean architecture — how a request moves through the layers

HTTP Pipeline

Entry · edge · middleware

API Request

An authenticated client issues an HTTPS request — REST verb, headers, JSON payload. Nothing trusts it yet; it must earn its way through every gate below.

HTTPSRESTJSON

Edge & Gateway

TLS terminates at the edge; the gateway resolves which microservice owns the route and forwards under balanced load. The first point a request can be rejected before touching application code.

CDNLoad BalancerAPI GatewayTLS

Middleware Pipeline

JWT authentication, RBAC authorization, rate limiting, idempotency keys, and tenant/locale resolution run in order. The request is shaped and gated before any controller is reached.
