I fix the problems that stop you from working — Outlook not sending, Windows login loops, email sync failures, profile corruption, OneDrive issues, and Microsoft 365 account conflicts. If your system is stuck, slow, or refusing to cooperate, I get it back online fast.
If you need something fixed today, I’m available for quick sessions and urgent troubleshooting.
I specialize in:
Outlook repair (send/receive failures, sync issues, OST/PST problems)
Windows troubleshooting (profiles, login loops, updates, performance)
Microsoft 365 issues (account conflicts, authentication, device access)
Email configuration (IMAP, CalDAV/CardDAV, migrations, app passwords)
Virtualization (Proxmox, Windows VMs, Ubuntu servers, snapshots, lab builds)
My approach is simple:
Clear diagnosis → fast fix → clean documentation → no surprises.
I’ve built and repaired everything from Outlook/Yahoo CalDAV integrations to Proxmox virtualization stacks and Windows environments with sync, login, and profile issues. Whether you need a quick repair or a deeper technical fix, I bring senior‑level troubleshooting without the enterprise overhead.

I'm a Cloud and AI Architect with 15+ years of enterprise experience, including 4 years at Microsoft on the Azure team where I consulted F500 companies like AT&T, Walmart, and Mastercard on AI, cloud adoption, security, and infrastructure at scale.
I founded TechVora, a small in-office engineering team based in Houston, TX. We work mainly with clients where security, compliance, and uptime are non-negotiable. All engineers work in-house, we never sub out work, which matters when sensitive data is involved.
WHAT MAKES US DIFFERENT
I act as the architect on every engagement and don't bill for my time. You get senior-level architecture, design, and oversight built into the cost of your developer.
AI & PRODUCTION SYSTEMS
Over the last two years we've shifted heavily into production AI - we've shipped four enterprise-grade multi-tenant AI applications across legal, accounting, oil & gas, and media, all involving custom LLM pipelines, RAG, and agents handling real sensitive data at scale.
CORE COMPETENCIES
- Cloud Architecture & Migration (Azure, AWS, GCP)
- AI/LLM Integration — RAG, Agents, Multi-tenant Production Apps
- DevSecOps, CI/CD, Infrastructure as Code (Terraform, Bicep)
- Data Pipelines, Warehousing & ETL
- HIPAA-Compliant Architecture
- Monitoring, Observability & Incident Response
- M365, Azure Security & Compliance
Happy to jump on a quick call - I offer a free strategy session for any new engagement.

I design and build large-scale data and AI systems that ingest, process, and act on data in real time. My focus is on creating platforms that combine automation, observability, and autonomous decisioning to perform reliably under real-world production pressure.
I bring 24+ years of experience architecting mission-critical systems across government, defense, healthcare, and enterprise environments, including classified DoD systems, NASA infrastructure, and large-scale healthcare platforms. Today, I extend that same foundation into modern AI and agentic systems.
I have led engineering organizations of 50+ engineers, architected multi-million dollar data platforms, and delivered 10x performance improvements in production systems. I maintain a 100 percent Job Success Score with consistent five-star reviews.
I build platforms that process millions of events per hour, operate under strict compliance requirements, and continue functioning when things go wrong. My work combines distributed systems, real-time pipelines, AIOps, machine learning, and agentic workflows with edge AI infrastructure to deliver enterprise-grade capability at practical scale.
Earlier in my career, I served as Chief Architect on HealthConcourse at Perspecta, a next-generation electronic medical records platform built on open, standards-based technology. The platform connected healthcare data producers, consumers, and services across a cloud-agnostic architecture designed for enterprise scale.
I was also an early employee at IronNet Cybersecurity, where I designed the core data platform for real-time threat detection across enterprise-scale telemetry.
More recently, I have focused on agentic AI systems, building autonomous decisioning layers using OpenClaw, ZeroClaw, NemoClaw, Hermes, NVIDIA NeMo, and Claude on top of proven data infrastructure. I design systems that incorporate retrieval-augmented generation (RAG), structured tool use via MCP, and multi-agent coordination with memory, routing, and safety controls. These systems are built for production from day one, with observability, governance, and operational control fully integrated.
Selected Engagements
Johnson and Johnson
Led enterprise AI and machine learning readiness assessment across large-scale healthcare data platforms. Re-architected pipelines, advanced master data management strategies, and guided governance for compliant AI adoption.
Result: Established a clear path for enterprise AI adoption, improving data readiness, governance, and scalability.
HealthConcourse Platform (Perspecta)
Chief Architect for a cloud-agnostic healthcare platform connecting data producers, consumers, and services across enterprise-scale infrastructure.
HP / HPE / DXC / Perspecta
Architected a $24M data and reporting platform integrating 2,000+ data sources into a unified Hadoop ecosystem. Delivered 50%+ efficiency gains through ETL modernization.
IronNet Cybersecurity
Early architect of a real-time analytics platform supporting machine learning-driven threat detection across distributed, high-volume environments.
Army DCGS-A (INSCOM)
Led multiple engineering teams in classified environments, delivering 10x performance improvements and sustaining near-100% operational readiness.
How I Work
I am hands-on at every level, from architecture to deep troubleshooting and performance tuning. I do not hand off the hard parts. I assess quickly, identify root causes, and deliver solutions that work in production.
Security and compliance are built into every design, including HIPAA, FISMA, and classified environments.
My career began as a United States Army Counterintelligence Special Agent. That background shapes how I build systems today. Adversarial by default. Resilient by design. No ambiguity.
I hold a Master of Science in Information Technology, along with Cloudera certifications in Hadoop development and administration and a Microsoft data science certification. I am actively preparing for the Claude Certified Architect credential.
When you hire a senior architect, you are betting your platform on their judgment. I have spent 24 years earning that judgment in environments where failure was not an option.
If that’s the level of experience you’re looking for, let’s talk.

I help founders and companies turn market and customer needs into the right product and technology solutions.
My strength is working at the intersection of business, customers, product, and technology. I listen to what people are actually trying to accomplish, uncover the underlying requirements, understand the technical implications, and translate those needs into practical direction for product and engineering teams.
I have spent years building software, working directly with customers and stakeholders, designing enterprise systems, launching products, and making the difficult decisions that come with turning an idea into something people will actually use.
AI has dramatically changed the economics of building software. Today, the advantage isn't simply being able to build something quickly. It's knowing what to build, what not to build, and how quickly you can determine whether you've built the right thing.
I bring that perspective to both startups and established companies.
WHAT I HELP WITH
⬛️ PRODUCT & MARKET STRATEGY
Understand customer needs, evaluate market opportunities, define product direction, identify product-market fit signals, and determine what is actually worth building.
⬛️ TECHNICAL DISCOVERY & REQUIREMENTS
Work directly with clients and stakeholders to uncover requirements, identify gaps and contradictions, ask the questions that matter, and turn ambiguous business needs into clear technical direction.
⬛️ AI-NATIVE PRODUCT STRATEGY
Help founders take advantage of the dramatically lower cost of building with AI, identifying what should be tested first, what can be built quickly, and where traditional product development processes create unnecessary cost and delay.
⬛️ ENTERPRISE SOLUTION ARCHITECTURE
Design and evaluate complex software solutions involving APIs, integrations, cloud services, applications, databases, and distributed systems. I focus on solutions that solve the business problem without creating unnecessary technical complexity.
⬛️ API & INTEGRATION ARCHITECTURE
Deep experience designing enterprise integrations and API strategies, including complex environments where multiple systems, teams, vendors, and requirements need to work together.
⬛️ CLIENT & STAKEHOLDER ADVISORY
Bridge the gap between technical and non-technical teams, explain complex technology clearly, challenge assumptions when necessary, and help clients and engineering teams reach a shared understanding of the solution.
WHY ME?
I'm a technical founder, not a consultant who only advises from the sidelines.
I've built products, hired developers, worked directly with customers, designed enterprise architectures, raised money, launched companies, and experienced both the successes and expensive mistakes that come with building technology.
I spent thousands of dollars and years building a code-generation product using the traditional development model. The technology worked. Customers loved the results. But the market ultimately told us the product wasn't right.
We listened and pivoted.
We later spent months researching and developing a much larger modernization platform based on what customers told us they needed. By the time we were ready to take it to investors, the investment market had moved on.
Those experiences fundamentally changed how I approach product development.
Today, I believe founders should use the dramatically lower cost of experimentation created by AI to get products in front of the market faster, listen carefully to what customers actually do and say, and invest heavily only after genuine demand begins to emerge.
The same principle applies to enterprise software:
LISTEN → UNDERSTAND → CHALLENGE → DESIGN → BUILD
WHAT I'M BUILDING
⬛️ THEDEVPLATFORM
A developer platform where engineers discover, nominate, vote on, and review development tools.
⬛️ SMARTCODE.NEWS
An engineering publication covering architecture, APIs, AI, and the technologies developers are actually building with.
⬛️ EVERYTHING API
Founder of the Everything API LinkedIn community, connecting developers and technology professionals with the latest API and integration news.
CREDENTIALS
⬛️ Speaker at MuleSoft CONNECT
⬛️ Speaker at API Days
⬛️ Technical founder and systems architect
⬛️ Extensive experience in enterprise integration, APIs, and software architecture
⬛️ Extensive client-facing and stakeholder experience
