I'm a full-stack web developer who builds custom websites and web applications that solve real business problems. I specialize in complex projects - ecommerce platforms, business management systems, and specialized tools that require careful architecture and custom features. I handle the complete technical lifecycle: custom development from scratch, database design, cloud and server infrastructure, domain management, and ongoing hosting and support. My experience spans payment processing integrations (Stripe), communication systems (Twilio), and scalable solutions built on platforms like Google Cloud and AWS. What sets me apart is my ability to translate complex requirements into clean, maintainable code and my commitment to transparent communication throughout the project. I don't just build websites - I create reliable, performance-optimized solutions that grow with your business. Whether you need a brand new platform, want to modernize an existing site, or require end-to-end technical management, I deliver on schedule and within budget. Let's discuss how I can bring your vision to life.

I help U.S. businesses navigate SMS approval, deliverability, and compliance requirements - reducing the risk of carrier rejections, blocked traffic, and regulatory issues. I specialize in A2P SMS compliance and deliverability, including 10DLC registration, Toll-Free Verification (TFN), and TCPA/CTIA consent audits, as well as diagnosing carrier-level delivery problems. My work focuses on aligning SMS programs with current carrier and regulatory expectations so they can operate and scale responsibly in the U.S. market. If your messages are being rejected, filtered, or delayed - or you’re unsure whether your consent flow and use case will withstand carrier or legal review—I can help assess and correct the underlying issues. What I Do • 10DLC brand & campaign registration (new submissions, rejections, reclassifications) • Toll-Free Verification (TFN) setup and resubmissions • TCPA / CTIA compliance audits (opt-in flows, disclosures, opt-out handling) • SMS deliverability diagnostics (carrier filtering, content flags, throughput limits) • Platform-specific guidance (Infobip, Twilio, GoHighLevel, ClickSend, SimpleTexting) • Compliance-aware SMS automation (webhooks, triggers, rate-limiting, quiet hours)

I build lead-response, quote follow-up, and renewal automation for insurance agencies and professional services firms. Three recent builds with evidence: A compliance consulting firm was losing leads that arrived in a Slack channel. I built Slack intake into Bigin CRM, an automatic templated email reply to the lead, and a sync that attaches the Fireflies call recording to the right pipeline record. Now, their leads are getting contacted right away, and nobody is falling through the cracks. A 4-person insurance agency runs on AgencyZoom, which has no native connector in n8n, Zapier, or Make. I built against their REST API directly: policy alert automations across five categories (non-payment, invalid payment, cancellation, missing documents, underwriting), service ticket creation from CSV uploads, inbound SMS auto-reply, voicemail auto-response, and a branded lead-capture page with TCPA consent capture. By responding to prospects instantly and following up, closing % has increased significantly, A B2B SaaS company needed its lifecycle email running. I built the Customer io campaigns, the Apollo outbound sequences, and the HubSpot and Calendly plumbing underneath them. Thousands of leads reached and hundreds of new customers. Common builds: Quote-to-bind follow-up. Renewal and retention cadences at 90, 60, and 30 days. Missed-call text-back and after-hours intake. Customer win-back sequences. Document extraction and reconciliation with a human review step. Stack Claude and n8n are my best friends (Zapier and Make too). Claude API and Python for document extraction and reconciliation. HubSpot, Bigin, Monday, AgencyZoom, Customer io. Twilio and RingCentral for SMS and voice. Webhooks and REST APIs for systems with no connector. Pretty flexible using anything with API documentation. How I work Fixed milestones when the scope is clear, hourly when it is not. The final milestone is always the system running live in your account with documentation. Documented builds and importable templates in my GitHub (linked) Shoot me a message and let's connect! :)
