Daniel Franco Fajardo — Principal Systems Architect, Critical and Intelligent Infrastructure


I design and govern systems that must remain reliable under real-world constraints across software, automation, edge infrastructure, and applied intelligence.

My value is not technology theater. It is architectural judgment under operational constraints.

Professional Positioning

I work at the intersection of architecture, operational reliability, and controlled technology adoption.

My focus is not isolated software delivery. It is the design of systems that must remain understandable, maintainable, and defensible when uptime, integration risk, compliance pressure, and deployment reality matter.

I contribute where technical scope, operational behavior, and delivery constraints must be translated into implementable architecture.

Core Signals

  • 9+ years across mission-critical transportation and industrial environments
  • Former Product Design Authority (PDA) for railway, tolling, and traffic-control platforms
  • international technical coordination across France, Italy, and Mexico
  • integration across PLCs, Modbus, sensors, SBCs, edge devices, software platforms, and validation environments
  • applied work in requirements analysis, gap evaluation, design trade-offs, R&D-oriented technology adoption, and operational validation
  • experience supporting technical proposals, compliance matrices, punch lists, supplier alignment, and executive / non-technical presentations
  • M.Sc. in Artificial Intelligence coursework completed; degree process underway

Proof Pillars

Critical Systems

Systems where uptime, continuity, fault handling, and maintainability matter.

Architectural Authority

System-level decisions, technical trade-offs, requirements framing, and risk-controlled implementation.

R&D / Technology Adoption

Evaluation of new technologies inside real delivery constraints, not detached experimentation.

Applied AI in Operations

Applied intelligence used as a bounded subsystem within governed operational environments.

What I Actually Do

This operating profile combines technical direction, validation discipline, and controlled delivery.

Requirements and Gap Analysis

I translate operational needs, bid constraints, and technical gaps into implementable system boundaries.

Trade-Offs and Decision Framing

I frame decisions around reliability, maintainability, cost, integration risk, and long-term operational behavior.

Tendering and Compliance

I support solution definition, technical annex interpretation, compliance alignment, and bid-oriented architecture shaping.

Integration and Validation

I work across PLCs, edge devices, software platforms, interfaces, and validation environments to reduce deployment uncertainty.

Operational Reliability

I prioritize observable, governable systems that fail predictably and remain defensible under real-world conditions.

Architecture foundations and cross-cutting engineering methods

Architecture, control, acquisition, evaluation, and delivery discipline are presented as one coherent implementation stack.

Professional Experience Highlights

  • Improved PLC-based vehicle classification effectiveness by 25% through logic optimization, process standardization, and validation improvements
  • Designed and implemented a Semi Stop & Go solution for elevated urban highway operations
  • Built real-time turnstile counting systems with Modbus communication, offline buffering, alerting, and fault-tolerant handling
  • Developed a PLC event simulator with Raspberry Pi to reduce test time and improve repeatability
  • Contributed to R&D-oriented evaluation of advanced sensing and applied intelligence without separating innovation from deployment constraints

Curated public evidence across GitHub Profile, GitHub Pages, PSRP, inventory-stream7-rescue, and EdgeResilienceLab

Evidence surface: public repositories and landing assets are organized as complementary proof points, not as competing project claims.

Selected project highlights including PSRP, inventory-stream7-rescue, GitHub Profile and Pages, and EdgeResilienceLab

Project signal: PSRP remains the primary technical proof; inventory-stream7-rescue demonstrates operational tooling; EdgeResilienceLab communicates publishable architecture direction.

Professional Boundary

This profile presents selected public architectural references and bounded prototypes.

It does not expose proprietary client code, confidential data, official warning systems, or production operational platforms.
