Diagnose
Map the system, risks, dependencies and decisions constraining the operation.
Alexsandro Freitas · Consultant & solution architect
Complex operations.
Designed into systems that work.
Productized consulting in solution architecture, cloud modernization, integrations, identity and applied AI — from diagnosis to delivery.
Real artifactSupply Plan / Architecture
Method
From ambiguity to operational capability.
Every engagement leaves decisions, artifacts and capability with the team — never a black box.
Design
Define target architecture, contracts, boundaries and modernization sequence.
Build
Deliver bounded APIs, integrations, interfaces and automations.
Transfer
Document decisions and leave context, operations and capability with the team.
Selected work
Projects explained through their artifacts.
Real diagrams, interfaces and decisions — with the evidence boundary made explicit.

Current practice · Appfy
Accelerators that make consulting more traceable.
Appfy turns operational and technical problems into architectures, automations, evidence pipelines and reusable accelerators. Repositories prove capability and execution; they are not, by themselves, a SaaS catalogue.
01
Alembic — agentic delivery engine
Canonical archive title: Alembic — motor de execução agênticaAn internal accelerator that turns AI consulting into traceable, repeatable execution.
M3
Open record in the catalogue →Consulting capability
- AI platform architecture
- Multi-agent orchestration
- Gates, receipts and fail-closed operation
- Provider integration and automation
Preserved evidence
- 27 packages and 1 app
- 1,027 TypeScript files
- 217 test files
- 255 commits in the local checkout
- 202 default-branch commits linked to the user in appfyai/alembic
The full suite was not rerun in this inventory and the checkout was dirty; this is not presented as a clean release or client SKU.
02
Framecast — video to multimodal evidence
Canonical archive title: Framecast — vídeo para evidência multimodalA knowledge-operations accelerator that turns video into auditable transcription, frame and analysis packages.
M4 no limite local
Open record in the catalogue →Consulting capability
- Multimodal pipelines
- Media processing
- Output contracts and resumability
- Knowledge curation
Preserved evidence
- 160 packages reconciled
- 159 real items and 1 fixture
- README, transcription.json and frames_manifest.json present in every package
No local Git history and no full semantic review of all 159 items; third-party media and transcripts are not published.
03
X research system and corpus
Canonical archive title: Sistema de pesquisa e corpus do XResearch engineering that separates identity, deduplication, structural validation and semantic audit.
M4 com gap ativo
Open record in the catalogue →Consulting capability
- Data engineering
- Authenticated extraction with explicit limits
- Quality and reconciliation
- Corpus traceability
Preserved evidence
- 1,278 unique IDs in the master corpus
- Structural validation passed
- 2 active semantic gaps explicitly recorded
The corpus is private and currently partial; only architecture, aggregate metrics and synthetic or consented material are shown.

- Executive synthesis
- Knowledge transfer
Preserved evidence
- 84,632-byte report with 5 SVGs and 12 sections
- 20 HTML pages
- 234 relative links with no missing destination
The proposed models, cluster and benchmarks were not executed in this inventory; external references require attribution.
05
Multi-agent accelerator family
Canonical archive title: Família de aceleradores multiagenteComputer Use MCP, Council Runtime, Agent Platform, AI Dev Kit and Loop Engineering as evidence of one delivery capability.
Evidência de repositório; maturidade varia por componente
Open record in the catalogue →Consulting capability
- Multi-LLM development environments
- Councils and cross-validation
- Desktop automation and agents
- Verification cycles
Preserved evidence
- 107 linked default-branch commits across five repositories
- All five are non-fork, non-empty and have strong contribution evidence
- Loop Engineering also has an Appfy local checkout
Five accelerators are not presented as five commercial products; owned material remains distinct from vendored content.
06
Delivery evidence in consulting projects
Canonical archive title: Evidência de execução em projetos de consultoriaPrivate repositories that support authorized Notion and diagram cases without exposing code.

- portal-credenciados, api-portal-credenciados and nestjs-keycloak-integration: linked contribution
- DynamoRelacionalPOC: linked contribution
Outcome, client and scope come from the authorized dossiers; a repository alone does not prove a result.

About
I work at the boundary between decisions and delivery.
I’m Alexsandro Freitas, founder of Appfy, solution architect and full-stack engineer. My practice combines problem investigation, architecture design, implementation and documentation so complex systems can be understood, evolved and operated.
This portfolio brings together the professional archive recovered from Notion, Miro, PDFs, GitHub, LinkedIn and the résumé. Scale, production or outcome claims appear only when supported by source material.
