I help General Contractors, EPC firms, and Owners build execution-ready projects before construction begins.
Control. Transparency. Structure.
That’s how complex construction projects stay aligned, controlled, and delivered successfully.
I build execution systems that bring these three elements into projects where coordination, cost, schedule, procurement, and risk must be managed—not assumed.
With 16+ years of experience across residential, hospitality, industrial, heavy civil, infrastructure, and mission-critical construction, I lead multidisciplinary teams of engineers and specialists in complex, fast-track environments where execution cannot be left to chance.
I operate at the intersection of preconstruction and field execution—translating drawings, specifications, contracts, and owner requirements into buildable scopes, sequencing logic, procurement strategies, and execution-ready work packages aligned with how projects are actually delivered.
My work focuses on aligning scope, cost, schedule, constructability, procurement, and project controls into a single coordinated system—where every activity is defined, every dependency is visible, every risk is identified early, and every outcome is measurable.
My experience spans mission-critical and industrial programs, including fast-track data center support works, large-scale water infrastructure, marine construction, mechanical piping, demolition, and complex field fabrication. I have also led residential and hospitality projects, including luxury developments and multi-year renovation programs—providing a practical understanding of construction execution across diverse sectors.
I take ownership across the complete preconstruction–execution interface, including:
Construction sequencing and schedule development
QTO / BoQ development and cost structuring
RFQ / RFP preparation, procurement strategy, and bid evaluation
Proposal development and tender documentation
Executive summaries, qualifications, assumptions, exclusions, and clarifications
Scope validation and subcontractor coordination
Technical risk identification across civil, structural, architectural, MEP, and process systems
Bid package QA/QC and submission readiness
Alongside this, I lead and coordinate engineering, estimating, and procurement teams—structuring workflows, validating deliverables, and ensuring alignment between design intent, commercial strategy, cost logic, procurement, and field execution.
I also develop Project Management Information Systems (PMIS), project workflows, procurement tracking systems, reporting dashboards, and standardized documentation that improve visibility, accountability, and decision-making throughout the project lifecycle.
My approach combines PMBOK® methodology with real-world construction execution—sequencing work as it is actually built, identifying risks before they become costly problems, and creating clear, traceable systems that support confident decision-making.
I don't rely on rigid software or predefined processes.
I build execution frameworks that adapt to the project—not the other way around.
I don't wait for structure—I create it.

I help SaaS companies, agencies, and government teams deliver complex technical projects on time — without the chaos.
15 years across Fortune 100 (Hewlett Packard Enterprise) and US government digital transformation (Granicus). At HPE I ran a multi-billion-dollar global portfolio across 150+ countries and cut deployment timelines by 20%. At Granicus I led public-sector digitization that changed how citizens reach essential services. On UpWork: 22+ projects · 5,000+ hours · 100% Job Success.
I now operate as SOTO⟂DEV — a doctrine-driven technical practice for businesses that have outgrown chaos. Most automation and software breaks within a year because it was built to demo, not to last. I work the opposite way: documentation-first, maintainable by your team, designed to outlive the technology it runs on.
What I deliver
– End-to-end project management (discovery → UAT → rollout) for SaaS and public-sector engagements
– Custom software & web apps — SaaS products, internal tooling, operational dashboards
– Automation architecture (n8n, Make, custom) with runbooks your team can actually maintain
– AI-assisted workflows (OpenAI, Anthropic) wired into your real CRM, not a toy demo
– Chatwoot deployments — multi-inbox, multi-agent, white-label-ready
– CRM optimization, SaaS operations, agile/sprint planning, cross-functional coordination
– Fractional technical operator engagements for founders and ops leaders who need a steady hand
How I work
– Written scope before any code. Written handoff after.
– Every system ships with a runbook, a recovery procedure, and a change log.
– Stakeholder communication tuned for both engineering teams and executive audiences.
– I optimize for the third year of the system, not the first week.
Who I am
Bilingual EN/ES, based in San José, Costa Rica (GMT-6). Available for US and EU time zones. Operating under a written doctrine — clients see it on day one, because the same standards that govern my code govern the engagement.
If you need a senior operator who's done this at Fortune 100 and government scale, won't disappear on you, and ships systems built to last — let's talk.
