If your project needs more than someone who writes code to spec — if you need someone who can architect the solution, own the delivery, and still be there for support six months later — that's the role I take on. WHAT I BUILD ──────────────────────── ✦ SaaS Platforms — multi-tenant, subscription-based .NET Core / Azure applications built to scale from a handful of users to enterprise volume ✦ Healthcare Systems — HIPAA-aware EHR/EMR platforms, HL7/FHIR integrations, and clinical workflow tools built to compliance standards ✦ Fintech & Payments — secure transaction processing, Stripe/PayPal integrations, reporting and reconciliation systems, PCI-conscious architecture ✦ E-Commerce Platforms — custom storefronts, order/inventory management, and integrations with payment gateways, CRMs, and ERPs ✦ Real Estate & Property Management Systems — listing platforms, tenant/lease management tools, and workflow automation for property teams ✦ AI-Powered Features — OpenAI/LLM integrations, intelligent document processing, and AI-assisted workflows added to existing .NET applications ✦ Legacy Modernization — turning outdated ASP.NET/VB.NET systems into maintainable, cloud-ready .NET 8 platforms without breaking what already works TECH STACK ──────────────────────── + Backend: C# · .NET 8 / .NET Core · ASP.NET Core · ASP.NET MVC · Web API · Entity Framework Core · LINQ · Blazor · SignalR · Microservices · REST & SOAP APIs + Frontend: Angular · React · TypeScript · JavaScript · HTML5 · CSS3 · Blazor UI + Cloud & DevOps: Microsoft Azure (App Services, Functions, AKS, Service Bus, Key Vault, Azure SQL) · AWS (EC2, Lambda, RDS, S3) · Azure DevOps · GitHub Actions · CI/CD · Docker · Kubernetes · Infrastructure as Code + Databases: SQL Server · PostgreSQL · Cosmos DB · MongoDB · Stored Procedures & Query Optimization for high-volume systems + Integrations: Stripe · PayPal · Twilio · SendGrid · OAuth 2.0 · HL7 · FHIR · CRM/ERP integrations HOW I WORK ──────────────────────── I stay involved from architecture through deployment — writing clean, documented, production-ready code, and communicating progress clearly at every step. I manage scope, timelines, and stakeholder expectations as carefully as I manage the codebase itself. Depending on what your project needs, I can work as a hands-on senior engineer, a solution architect, or a long-term technical lead. I'll tell you honestly, early, if I'm the right fit for what you're building. Send me your project scope and I'll respond within a few hours.

Helping manufacturing and industrial teams build scalable CPQ, quoting, pricing automation, quote generation, proposal generation, and quote-to-cash systems that actually work in real sales operations. Experience working with CPQ platforms including Salesforce CPQ, Revenue Cloud, Oracle CPQ, Apttus CPQ, custom product configurators, and pricing automation solutions. Verticals: industrial equipment, HVAC & mechanical contractors, contract manufacturing, building materials, engineered products, custom assemblies, field services. Where I've helped: Spreadsheets → structured quoting & pricing automation Moved pricing logic, product configuration rules, pricing configuration, quote generation processes, and approval workflows out of Excel into scalable CPQ and quote management systems sales reps can actually use without breaking pricing. Homegrown tools → maintainable quote-to-cash systems Preserved existing business logic while removing single-developer dependency and improving maintainability, quoting workflows, sales operations visibility, CRM automation, and RevOps processes. Document builders (PandaDoc, Qwilr) → automated proposal generation Connected configuration, pricing engines, CRM data, Salesforce CRM, and ERP systems so quotes, proposals, SOWs, and sales documents generate automatically from rules instead of manual assembly. Heavy CPQ (Salesforce CPQ, Oracle CPQ) → right-sized implementation Simplified existing CPQ setups, pricing workflows, quote generation processes, product configuration models, and product configurators — or replaced overengineered systems with tools that better match how the sales team actually sells. Quote-to-cash workflow setup end-to-end Quotes → proposals → contracts → e-sign → sales orders → fulfillment Built full document automation flows with branded proposal generation, contract generation, approval routing, e- sign integration (DocuSign, PandaDoc, native e-sign), and downstream Sales Order / Purchase Order automation. Approved quotes flow directly into fulfillment without manual re-entry, duplicate data entry, pricing mismatches, or version control issues between sales and operations. Experience with: CPQ, Configure Price Quote (CPQ), Salesforce CPQ, Revenue Cloud, pricing automation, pricing configuration, proposal automation, sales quoting, quote generation, proposal generation, RevOps workflows, Quote to Cash (QTC), sales document automation, CRM automation, Salesforce CRM, Salesforce Sales Cloud, product configuration, approval workflows, contract management, ERP/CRM integration, API integration, subscription pricing, dynamic pricing, sales operations, and quote-to-cash processes. Not sure where to start? Send a quick overview of your current quoting process, pricing workflow, quote generation process, CPQ implementation, or proposal generation setup — I’ll take a look and share what I’d improve, no commitment required.
