WordPress systems engineer specializing in CRM architecture and email deliverability. I audit, stabilize and rebuild mission-critical WordPress and CRM stacks for businesses that need them reliable. If your WordPress or CRM system is unstable, slow, or quietly costing you customers, I help you regain control quickly and safely. My work centers on three things: WordPress systems engineering deep technical audits, complex bug troubleshooting (race conditions, cron reliability, background jobs), custom PHP and MU-plugin development, and performance and security hardening. CRM architecture full CRM builds, segmentation, automations, pipelines and integrations on FluentCRM, ActiveCampaign and Klaviyo, plus clean migrations between platforms with automation parity and a rollback plan. Email deliverability engineering SPF, DKIM and DMARC alignment, blacklist remediation, provider strategy, and inbox-placement monitoring built to current Gmail and Yahoo bulk-sender rules. I also handle automation and integrations (n8n, Make, Zapier) when a stack needs its tools to work together. I work with businesses, organizations and established brands that need a senior technical partner they can trust: to protect reputation, modernize critical workflows, or recover from unstable or poorly-implemented systems. Every project is approached with structure, documentation and long-term maintainability in mind. Typical engagements: → System audits (CRM, deliverability, WordPress security and performance): prioritized roadmap, fixed deliverables → CRM builds and migrations: full automation parity, rollback plan included → Email deliverability engineering: DNS, provider strategy, inbox-placement monitoring → Complex bug fixes: race conditions, cron reliability, background tasks → Rebuilds and automation migrations: full-stack rebuilds, data migrations, QA, documentation Trust: Top Rated, 100% Job Success, 14 completed contracts at 5.0, ID verified. Bilingual EN/FR. How to start: → Book the 1-hour CRM / email / WordPress diagnostic call ($35 fixed) for a prioritized action plan → Request the free deliverability audit (PDF in 24h, no obligation) → Send a message with your stack and the problem.

I help companies secure their Google Cloud infrastructure and fix broken analytics pipelines — without the guesswork. Most recently, I worked as embedded GCP infrastructure and marketing-analytics support for a client over 220+ hours (5-star review), handling cloud architecture decisions, security hardening, and analytics setup end-to-end. Before that, I spent 5 years as a Security Engineer at SGS Ghana, where I reduced infrastructure provisioning time by 70% through Terraform automation and cut production misconfigurations by 40% via CI/CD security controls, while managing security across 20+ technology vendors. Where I add the most value: Cloud Security & Infrastructure GCP architecture design, IAM/zero-trust policy enforcement, Terraform IaC Kubernetes (GKE) hardening, container security ISO 27001 / SOC 2 technical compliance mapping Analytics & Data Engineering Server-side GTM, GA4 → BigQuery pipelines, SQL schema work Conversion tracking (Meta CAPI, Google Ads) for teams with attribution gaps Google Apps Script automation for internal ops I'm Google Cloud certified (Professional Cloud Security Engineer) with additional skill badges in DLP, BeyondCorp Enterprise, network security, and DevOps workflows on GCP. If you're dealing with a cloud security gap before an audit, or an analytics pipeline that's quietly losing data, send me your current setup and I'll tell you plainly what's broken and what it'll take to fix it.

When your documentation is unclear, incomplete, or buried in a developer's head — your users struggle, your support team drowns, and your product adoption stalls. I fix that, and I do it faster and smarter than a traditional technical writer. I'm a Top Rated Plus Technical Writer with a 100% Job Success Score across 28 completed projects and $100K+ earned on Upwork. Over 6+ years, I've helped SaaS companies, API-first products, fintech platforms, cybersecurity firms, and Web3/blockchain products build documentation that actually works — content that reduces support tickets, accelerates onboarding, and gives your users the clarity to act. I've built and maintained documentation for brands including Alchemy (Web3 infrastructure), BoostSecurity (CI/CD security), and WoodCore (banking platform), from ground-zero API reference builds to full developer portal architecture, knowledge base migrations, and DevRel content programs. What makes me different: I'm AI-native. I don't just use AI to write faster — I build documentation systems. I design and implement AI-augmented documentation workflows using tools like GPT-4, Claude, and custom LLM pipelines integrated with docs-as-code frameworks (Mintlify, Docusaurus, GitBook) to auto-generate drafts, validate API references against OpenAPI specs, and keep docs in sync with fast-moving codebases. For engineering teams shipping rapidly, this means documentation that ships with the product instead of six weeks after it. What I can take off your plate: → API Documentation (REST, OpenAPI/Swagger, Webhooks, SDK guides) → SaaS User Documentation & Product Guides → Developer Portals & Integration Docs → DevRel Content (Tutorials, Quick Starts, Code Walkthroughs, Changelogs) → AI-Augmented Documentation Systems & Automation Workflows → Help Center & Knowledge Base Architecture → Cybersecurity & Compliance Documentation → AI/LLM Product Documentation & Technical Whitepapers How I work: I integrate directly with your engineering, product, and DevRel teams — not as an outsider who needs hand-holding, but as a documentation partner who ramps fast, uses your stack, and delivers docs your team can maintain and extend. I'm proficient with OpenAPI, Swagger, Postman, Mintlify, Docusaurus, GitBook, Confluence, Markdown, Git, and Jira, and I build AI-assisted workflows that keep your documentation accurate as your product evolves. Proven results: ✔ Reduced support tickets by 30%+ across 30+ companies through improved documentation ✔ 100% Job Success Score across 28 completed projects on Upwork ✔ 6+ years spanning SaaS, fintech, cybersecurity, and blockchain products ✔ Available immediately — response time 0–4 hours Ready to fix your documentation? Message me today, and I'll respond within 4 hours. I'm open to short-term audits, one-time projects, long-term retainer engagements, and embedded DevRel content partnerships.

I build secure internal AI copilots and enterprise search systems that connect your documents, CRM, databases, Slack, email, and internal tools so your team can get answers, trigger workflows, and automate repetitive work with confidence. If you need more than a chatbot demo, I can help you ship a production-ready AI system with grounded answers, citations, clean tool integrations, human handoff where needed, and clear evaluation. What I build: • Internal copilots for operations, support, sales, and knowledge teams • Enterprise search / RAG systems over SOPs, policies, contracts, tickets, product docs, and databases • MCP and API integrations for CRMs, helpdesks, Slack, email, Postgres, and internal tools • Workflow automation that updates records, routes tasks, sends follow-ups, and closes manual loops • Evals, tracing, and observability so answer quality improves over time • FastAPI backends, Python services, dashboards, and deployment-ready architecture Common outcomes: • Faster internal answers for teams • Fewer repetitive support tickets • Better lead routing and cleaner CRM workflows • Safer document Q&A with citations • Less manual operational work across disconnected systems I work with: Python, FastAPI, OpenAI, Claude, MCP, PostgreSQL, pgvector, Qdrant, Weaviate, Langfuse, n8n, webhooks, REST APIs, React, and Next.js I do not focus on AI theatre. I focus on useful systems that are measurable, maintainable, and tied to real business workflows. If you already know your bottleneck, send me the workflow and tool stack. If you do not, I can help you design the shortest path to a reliable internal AI system.
