Engineering for financial institutions
For more than three decades in the financial ecosystem, MRemittance combines deep domain knowledge, public-cloud architecture and intelligent-agent orchestration to replace critical slices of processes still locked into traditional banking cores.
MRemittance is an engineering and project firm for banks and non-bank financial companies. Headquartered in Brazil with a strong presence in West Africa (Cape Verde), we also deliver in Angola — with the same standards for architecture, security and governance the industry demands.
The founding partner has spent more than four decades in IT, including Brazil’s leading banks — Banco do Brasil, Caixa Econômica Federal, Bradesco, Itaú and Santander, among others. Many initiatives led or co-authored became reference points for the sector.
Several engagements have been recognised as innovative and disruptive in Brazil and internationally. Today we channel that history into a clear proposition: modernise critical paths in your digital ecosystem without sacrificing compliance, auditability or legacy integration.
Engagements typically span architecture assessment, solution design, implementation and production support — always with measurable business outcomes and reduced operational risk.
Domain modelling, integrations, SLAs, security and cloud economics — turning business and regulatory requirements into an executable blueprint.
Transactional systems, APIs, queues, batch jobs and interfaces to financial software vendors — with reviewable code and audit-ready documentation.
Gradual extraction of processes from the core when it makes technical sense — with feature flags, observability and rollback plans.

Read paper →Cloud is not an add-on in our work — it is the default. We size workloads, networks, identity, encryption and cost across AWS, Microsoft Azure and Google Cloud Platform, choosing the provider (or multicloud pattern) that best fits your strategy and contractual constraints.
Accounts, organisation, IAM, private networks, controlled internet exposure, secrets and backup policies — a solid base before any “innovation layer”.
Patterns for environments that need audit trails, segregation of duties, encryption in transit and at rest, and monitoring aligned with risk committees.
Technical & architectural specialties
We design and run multi-agent networks that plan, decide and execute end-to-end flows — with enterprise RAG, serverless integration and guardrails for regulated domains such as core banking and microcredit.
Autonomous agent networks coordinated by robust frameworks (e.g. AWS AgentCore) to plan, decide and execute complex end-to-end work.
Agents connected to living knowledge bases and vector stores in the cloud — precise retrieval with a zero-hallucination focus.
AI architectures for highly regulated environments — controlled replacement of core banking and microcredit flows.
Custom tools via AWS Lambda and hardened APIs so agents can act safely on relational databases, ERPs and CRMs.
LGPD and financial-compliance barriers, human-in-the-loop approvals and token-cost control — full audit of each agent decision.
Amazon Bedrock and cloud best practices to scale natively, securely and with predictable infrastructure cost.
Financial systems leave no room for error. Resilience by design and a complete trail over every decision process.
Bedrock and serverless stacks that scale with security and strong cost efficiency.
Credit, reconciliation and operational journeys become coordinated flows agents execute with human oversight.
We serve financial institutions and non-bank players in the three markets below, with awareness of each regulator’s and operating context.
Brazil — headquarters and largest project footprint
Cape Verde — West Africa subsidiary
Angola — growing delivery and partnerships
For small and mid-sized banks and non-bank players, the leap is not “having a website”: it is putting supervised flows into production — explicit policies, audit trails and legacy integration — with agents and models as an extension of the core, not a brochure.
