Cases, experience, contextualized stack, deployment, infrastructure and production operations.

Enterprise implementations spread tasks, risks, evidence, tests, documents and decisions across multiple fronts, making traceability and go-live tracking harder.

Multi-tenant SaaS platform to plan, execute, validate and track implementation projects from start to go-live, including customer portal, reports and audit.

Next.js frontend, Fastify API, PostgreSQL with RLS, Redis/BullMQ, RabbitMQ, MinIO and an asynchronous worker for notifications, reports and integrations.

Reproducible environment with Docker Compose, Nginx, health checks, Prometheus/Grafana/Loki observability and a CI pipeline.

The technical delivery brings planning, execution, validation, documents, reports, integrations, customer portal, audit and observability into a single multi-tenant foundation.

Enterprise integrations across APIs, databases, files, SFTP and webhooks require reliable execution, traceability, failure handling and reprocessing.

Multi-tenant iPaaS with visual flow editor, connectors, versioning, manual/scheduled/webhook execution, replay, structured logs, retry and DLQ.

Control plane on Next.js/Fastify/PostgreSQL and a data plane based on Redis/BullMQ, distributed workers, scheduler, connectors and MinIO artifacts.

Stack prepared for Docker Compose and Nginx, stateless services, Prometheus/Grafana/Loki observability and a smoke test covering flow, webhook and artifacts.

The technical flow covers modeling, triggering, distributed execution, retry, replay, step-level tracking and Dead Letter Queue without depending on a single integration type.

Financial processing must prevent duplicates, keep entries balanced, identify risk and reconcile sources without losing traceability.

Multi-tenant platform with idempotent ingestion, immutable double-entry ledger, explainable fraud rules, investigation, reconciliation and daily settlement.

Fastify and Next.js on PostgreSQL with RLS, Redis/BullMQ and independent workers for ingestion, fraud, reconciliation and settlement, with MinIO for evidence.

Containerized environment with Nginx gateway, separated services, health checks, Prometheus/Grafana/Loki and CI with automated validations.

The implementation closes the transaction → ledger → fraud → reconciliation → settlement cycle while preserving idempotency, auditability and compensating entries for refunds and chargebacks.

Monitoring alone does not solve operational response: checks, incidents, on-call, maintenance, runbooks and status communication need a shared context.

Multi-workspace Reliability Command Center with HTTP/TCP/heartbeat monitors, incidents, on-call, runbooks, maintenance windows, postmortems and public status page.

Next.js and Fastify with PostgreSQL/RLS, Redis/BullMQ and a monitoring worker responsible for checks, failure thresholds, recovery and automatic incident creation.

Stack prepared for Docker Compose and Nginx, health checks, Prometheus/Grafana metrics and separated services for the application and monitor execution.

The implemented operational cycle connects check, state change, incident, timeline, alert and recovery, with maintenance support and public status communication.
