Granular Access Control. Zero Operational Friction.
Enterprise-grade Role-Based Access Control engineered for field workforces. Sub-millisecond Redis permission evaluation, shift-guarded customer visits, and automated NIST privilege escalation defenses.
Redis SISMEMBER Set Evaluation
Constrained Floor & Ceiling Policies
Double Clock-In & Overlap Proof
Verified On-Duty Field Logging
Unified Field & Security Command
Explore how FieldOps bridges high-assurance dynamic authorization with real-time field workforce logistics.
Zero-overhead role assignments and dynamic updates.
Permissions are resolved via Redis Sets in sub-millisecond time. When a role is edited, non-blocking pipeline invalidation instantly propagates changes to all active users without requiring logout.

Engineered with sub-millisecond Redis memory evaluation, strict NIST level 2 policy guards, and transactional PostgreSQL persistence.
Trace an Inbound Request Through the Backend Layers
Checks role permission key (`rbac:perms:${userId}`). Sub-millisecond evaluation with OWNER bypass.
SISMEMBER rbac:perms:usr_998a12bc READ_ALL_VISIT → 1 (Permission Granted)
Sub-ms SISMEMBER Evaluation
Permissions are stored as Redis Sets (`rbac:perms:${userId}`). Guards query `SISMEMBER` in O(1) time (<0.4ms), bypassing Postgres for read paths while supporting full atomic pipeline invalidations.
NIST Constrained Policy Guards
Strict floor constraints ensure field staff can never be stripped of clock-in abilities, while ceiling caps prevent privilege escalation. OWNER superusers are completely immutable.
Shift State Machine & Locks
Prevents double clock-in concurrency races with strict active session checks. Calculates exact millisecond duration upon clock-out and expands midnight queries automatically with zero timezone drift.
Operational Field Compliance
Customer visits strictly enforce active shift attendance. Field employees cannot record visits while off-duty, producing auditable compliance logs with zero ghost entries.
Sole Owner Lockout Defense
The system actively enforces that at least one Owner remains active. Demoting or deactivating the last active Owner is hard-blocked at both policy and repository layers with 400 Bad Request.
Deterministic MD5 Cache-Aside
Query filters are hashed alphabetically via MD5 into keys (`visits:self:uid:hash`). Mutations execute non-blocking SCAN pattern sweeps, guaranteeing zero stale data with sub-millisecond read times.
