Open for projects and collaborations
Ganmarie Duque
Software Engineer
I keep most of my work invisible, which is the point.
You only hear about it the day it stops being invisible.
01What I do
-
Product engineering
Empty repository to something people actually use, then the unglamorous half: migrations, tests, CI/CD, and the deploys nobody has to schedule around.
-
Critical-path integrations
The flows that aren't allowed to fail quietly. Third-party APIs, webhooks that arrive twice or not at all, and the reconciliation jobs for when reality disagrees with the database.
-
AI systems
Agents with real tools and generative pipelines that route each job to whichever model does it best.
02Work
-
2023 - Present
Autopilot Solutions, Inc.
A B2B platform for home-service businesses covering scheduling, dispatch, invoicing, payments, and telephony, taken from empty repository to production.
- Architected the telephony layer: per-company Twilio subaccounts, automated A2P 10DLC registration, call routing with whisper and voicemail, and a softphone in the mobile app.
- Built the full Stripe money path: Connect onboarding, subscriptions with invoice retries, deposits, booking payments, and in-person terminal readers.
- Cut delivery failures 60% with reconciliation jobs, error-specific remediation, and logging that says what actually happened.
- Shipped an OAuth 2.0 server and webhook API that made Autopilot a published Zapier app.
-
2021 - 2023
Freelance & Contract
Three production platforms in three unrelated industries, which is the fastest way to learn that every domain thinks it's the special one.
- Scout by Spacesium3D drone spatial analytics with IAM auth, Lambda processing, and EC2
- OmniReal-estate CRM on Firebase, Lambda, and S3
- Nodac FinanceSolidity & Hyperledger smart contracts, sole engineer
-
2021
Bit Create IT Solutions
Web applications for startup clients, plus the first bugs I ever shipped to production, then fixed.
03Projects
-
GhostReach
ghostreach.xyzAgencies run SMS, voice, and email campaigns for their whole client roster under one account, with every tenant isolated, billed, and compliant without a human in the loop.
- A2P 10DLC compliance automated end to end: Trust Hub profiles, brand and campaign registration, per-tenant subaccounts with scoped keys.
- Email infrastructure that provisions itself: domain search, mailbox orders, warmup reconciliation, launch.
- White-label mode: branded agency portals on custom domains via the Vercel Domains API.
- Thirteen providers behind one interface, from Stripe and Twilio to Firecrawl and Apollo.

Wally OS
wallyos.comGive it a trade and a town and it goes: registers the domain, files the LLC, publishes the site, runs the ads, and answers the phone when customers call.
- LLM tool definitions with real side effects: domain registration, LLC filings, ad campaigns on Google and Meta, live phone calls.
- A video pipeline that routes each scene by shot type across Veo, Kling, Seedance, OmniHuman, and HeyGen, rendered on Remotion and Lambda with hand-written SigV4 signing.
- Generative image and logo work across gpt-image-1, Gemini 3 Pro Image, Stability, and Recraft, so a brand new business has a mark and photography before it has a customer.
- ElevenLabs speech with character-level timestamps, so captions land on the syllable.
- Finished video and image ads post themselves: the agent uploads the creative, builds the campaign, and schedules the run inside the Google and Meta accounts it opened.
- Every customer site gets its own Vercel project, GitHub repo, and sandbox. Multi-tenant down to the infrastructure.

Let's make something worth the caffeine.
The unglamorous parts are my favorite parts. Tell me what keeps breaking.
