Eddie T.

I help founders, business owners, and engineering teams ship production Next.js, TypeScript, and Python applications, build reliable WordPress, WooCommerce, Shopify, and Webflow websites, wire up Twilio, Telnyx, and Make AI voice/SMS automations, fix urgent backend bugs, and harden Stripe, Cloudflare, and database pipelines without ongoing hand-holding. Over 10 years as a software engineer in Boston (6 years building backend SMS, email, and voice messaging systems at Jobcase, 4 years at Raytheon, and a BS in Computer Science from Brandeis University), I have built and operated high-volume backend services, AI call-handling agents, and event-driven pipelines supporting millions of users alongside live production web platforms. Production Engineering & Live Systems Track Record: • Front Desk Answer (AI Voice Receptionist & Missed-Call Recovery): Built a real-time AI phone agent, missed-call text-back, and service/order dispatch platform (FastAPI, async SQLAlchemy/PostgreSQL, Next.js on Cloudflare Workers). Engineered a bidirectional WebSocket audio bridge connecting Telnyx Call Control and Twilio Voice/SMS with Deepgram Nova-3 real-time STT, ElevenLabs streaming TTS (with caller barge-in handling), and LLM state-machine guardrails (OpenAI, Gemini, Vapi, and Make), backed by 700+ automated Pytest and Vitest tests. • EasyPayRequest (Multi-Tenant Stripe Billing & Invoicing SaaS): Built and operate a live multi-tenant Stripe Connect billing, payment request, recurring invoicing, and ledger reconciliation SaaS using Next.js, TypeScript, and PostgreSQL, with duplicate-safe webhook handling, idempotency locks, and verified Cloudflare and Resend DNS setups. • Messaging, SMS/Email & Event Pipelines (Jobcase, 6 Years - Communications Compliance Tech Lead): Led the Communications Compliance team and built high-volume SMS, transactional email, and real-time notification services on AWS (Kinesis, SQS, S3), Kubernetes, SQL, and Amazon Redshift for millions of users. Built a Twilio AI call-handling agent, integrated OpenAI/ChatGPT into production messaging workflows, unified two compliance systems post-acquisition, and owned observability and on-call triage across Datadog, New Relic, and Sumo Logic. • Custom Recruiting Platform, WordPress Hubs & Inbound Email Pipeline: Built a full-stack job board, candidate directory, and recruiter dashboard (React, TypeScript, Express/tRPC, MySQL), plus custom WordPress/Elementor vertical landing hubs bridged under the main domain via a Cloudflare Worker reverse proxy with modal lead-capture routing, Google JobPosting schema, Resend SPF/DKIM/DMARC setup, inbound email reply threading, and signed resume downloads. • Shopify OS 2.0 Theme Engineering, Custom Configurators & Mobile Checkout CRO: Built custom Shopify Liquid and JS storefront features (multi-option framing/matting gallery previews, dynamic price-summary bars, sticky mobile buy bars, and AJAX slide-out cart drawer sync), automated variant media updates via the Shopify Admin GraphQL API, and resolved mobile checkout drop-offs and Meta Pixel, Conversions API (CAPI), GA4, and Microsoft Clarity attribution gaps across iOS Safari and in-app browsers. • Defense Systems & Test Automation (Raytheon, 4 Years): Engineered C++ and MATLAB radar systems, built automated subsystem test environments, and integrated static analysis tooling that saved over $500,000. Core Technical Stack: • Languages & Frameworks: Python (FastAPI, Async SQLAlchemy, Alembic, Playwright, Pytest), TypeScript, JavaScript, Next.js, React, Node.js, Tailwind CSS, Shopify Liquid, HTML/CSS, PHP, Java (Spring Boot), C++, SQL. • Voice AI, Telecom & Automation: Twilio (Voice, TwiML, SMS, A2P 10DLC), Telnyx (Call Control, Media WebSockets), Deepgram (Streaming STT), ElevenLabs (Streaming TTS), Vapi, Make, n8n, OpenAI, Anthropic & Gemini Tool Calling. • Payments, E-Commerce, CMS & Cloud DNS: Stripe API (Checkout, Connect, Subscriptions, Webhooks), Shopify (OS 2.0 Liquid, AJAX Cart, Admin GraphQL API, Webhooks), WordPress (Elementor, WooCommerce, Custom Themes/Plugins, REST API, Core Web Vitals), Webflow, Squarespace, Meta Pixel & CAPI, GTM & GA4, Cloudflare (Workers/Pages, OpenNext, DNS, SSL/TLS), Resend (SPF, DKIM, DMARC). • Infrastructure, Data & Observability: AWS (Kinesis, SQS, S3, SSM, Elastic Beanstalk), Vercel, Supabase, Railway, PostgreSQL (PgBouncer, asyncpg), MySQL, Redshift, Docker, Kubernetes, OpenTelemetry, Datadog, New Relic, Sumo Logic. How I Work: For new clients and urgent fixes, I start with a fixed-price initial milestone (a diagnostic audit, root-cause bug fix, responsive page build, or scoped Twilio/Telnyx/Make/API/DNS/Shopify/WordPress integration) delivered within 24 to 48 hours. You get clean, tested systems and zero production downtime before moving into larger milestones.
