Critical platforms that turn technology into business scale

I lead engineering in high-scale environments, combining distributed architecture, reliability, payments, and governed artificial intelligence. I build platforms that increase team autonomy, reduce operational risk, and deliver measurable results.

Bruno Silva

I have led transformations at Serasa Experian, Visa, and Mercado Libre, coordinating multidisciplinary teams across Engineering, Product, SRE, DevSecOps, Security, Compliance, Finance, and commercial organizations.

What I deliver

Strategy, architecture, and execution connected to customer, operational, and business metrics.

Governed applied AI

Agents, RAG, MCP, evaluations, autonomy limits, auditability, and human review for financial operations and critical back offices.

Financial platforms

Ledger, idempotency, events, reconciliation, antifraud, reversals, and end-to-end traceability in regulated environments.

Reliability and scale

SRE, observability, low latency, capacity planning, resilience, and predictable handling of traffic peaks.

Platforms and autonomy

Shared capabilities, self-service, delivery standards, and operating models that remove repetitive work from engineering.

Featured case studies

Four transformations led at real-world scale, with technical and business impact.

How I apply AI in critical environments

I integrate AI into operational architecture with security, clear objectives, and explicit accountability.

1Real problemDefine the outcome, risk, and baseline before choosing a model.
2Trusted contextRAG grounded in validated rules, events, and procedures.
3Bounded toolsMCP, scope, permissions, and explicitly allowed actions.
4Evidence and evaluationsConfidence, traceability, cost, and quality.
5Human decisionMandatory escalation for sensitive cases.
Finance

Intelligent reconciliation

Agents correlate events, ledger entries, tracking IDs, and settlements to investigate discrepancies and recommend actions.

Operations

Assisted back office

Commercial users validate launches, data, and inventory without turning engineering into an operational support layer.

Governance

Human-in-the-loop

Low confidence, inconsistent output, or financial impact routes the case to a human owner before execution.

Principle: AI accelerates investigation, improves consistency, and reduces manual work; accountability, authorization, and financial decisions remain explicit and auditable.

Experience that connects technology and business

End-to-end leadership

My work combines architectural decisions with team design, clear ownership, and operational governance. I have led initiatives ranging from high-traffic shared platforms to regulated financial integrations and international operations.

I work closely with Product, Engineering, SRE, Infrastructure, Security, Finance, Legal, Compliance, and commercial teams. The goal is not simply to modernize technology, but to turn platforms into engines of growth, reliability, and autonomy.

For AI, I prioritize use cases with verifiable impact, including financial reconciliation, exception investigation, launch validation, and context-aware automation. Each application uses evidence, boundaries, and oversight appropriate to its risk.
