floework is a modern collaborative execution platform engineered for high-velocity software engineering teams. Rather than relying on invasive screen tracking, shallow status counters, or fragmented spreadsheets, floework pairs real-time collaborative task execution with quantified focus sessions, directed acyclic graph (DAG) dependency intelligence, and executive AI summaries.
The platform has undergone a comprehensive, zero-downtime architectural evolution: transitioning from an early monolithic prototype into a production-hardened, decoupled cloud platform on Amazon Web Services (AWS) using Infrastructure as Code (Terraform), zero-lock Optimistic Concurrency Control (OCC), asynchronous FIFO queues, and keyless GitHub Actions OIDC pipelines.
The floework platform runs on a Multi-AZ Virtual Private Cloud (VPC) designed according to the AWS Well-Architected Framework:

- Eliminates destructive database row locks during high-frequency collaborative sprint planning.
- Every task mutation enforces
version = client_versionsequencing. - Conflicting writes instantly return
HTTP 409 Conflict(STALE_UPDATE), log structured audit metadata toconcurrency_conflicts, and trigger client-side randomized jitter reconciliation (50–200ms).
- Replaced monolithic server-bound sockets with Amazon API Gateway WebSockets backed by Amazon DynamoDB connection registry.
- Supports high-frequency presence pulses (In Focus, Available) and Kanban column drags without server memory leakage.
- Workspace-level fan-out achieved in
< 5msvia Amazon ElastiCache Redis Pub/Sub.
- Critical path HTTP requests (such as deep work session completions) offload heavy stability scoring to Amazon SQS FIFO queues (
focus-completion.fifo,audit-logs.fifo,notifications.fifo). - Handlers respond immediately with
HTTP 202 Accepted(< 15msresponse latency). - Resilient worker processes leverage 20-second long polling and automated routing to Dead-Letter Queues (DLQ) after 3 failed attempts.
- Automated delta synchronization engine (
scripts/cutover_delta_sync.mjs) replays records in strict topological dependency order across all 7 core domain tables. - Employs transactional idempotency (
ON CONFLICT (id) DO UPDATE) and SHA-256 checksum digests. - Supports reverse replication mode (
--reverse) providing a 48-hour safety net during cutover.
- Workflows authenticate to AWS using short-lived tokens via AWS STS (
AssumeRoleWithWebIdentity) bound torepo:Atharva-Mendhulkar/floework:*. - Zero static AWS Access Keys (
AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY) stored in GitHub Secrets. - Automated container builds with Docker Buildx, Trivy vulnerability scanning, and push to Amazon ECR.
- Powers Floework's
@xyflow/reactExecution Intelligence Graph. - Server-side 3-color topological DFS (
UNVISITED,VISITING,VISITED) rejects self-loops and circular dependencies (A -> B -> Aor transitiveA -> B -> C -> A) withHTTP 400 Circular dependency detected. - Features real-time downstream blocker cascade calculation and critical path identification.
- Declarative cost control layer managed via
terraform/modules/finops/with multi-tier AWS Budgets (50%, 80%, 100% actual + 100% forecasted) routing alerts to the SNS operational bus. - AWS Cost Anomaly Detection running dimensional service monitors with $10 (staging) / $20 (production) root-cause impact triggers.
- Automated FinOps CLI audit engine (
scripts/finops_cost_audit.mjs) evaluating idle resources, unattached storage, NAT Gateway consolidation, and baseline run-rates:
$ node scripts/finops_cost_audit.mjs --multi-az-nat
