Dev Ganugapenta

Full-stack and AI product development for startups and enterprise clients. The ventures and platforms below were built through this practice.

• •Built four startup products from zero to market as founding engineer, two now generating revenue, alongside enterprise platform delivery for corporate clients.
• •Top Rated Plus on Upwork with 100% Job Success; every completed engagement rated 5.0.

AI Navigator, an enterprise AI readiness platform. Live at navigator.leadingwith.ai.

• •Owned the platform end to end: built the GPT-4o assistant that navigates the app and runs analyses for the user, and a sentiment engine scoring 1,000+ employee survey responses on where and why AI adoption stalls.
• •Delivered Phase 1 ahead of the client’s Web Summit 2025 presentation, then wrote the Phase 2 proposal (scope, team, budget) and won the follow-on contract.

Field-service SaaS for service businesses. Live at dyia.io with paying subscribers.

• •Built the company’s product from zero to launch in two months: crew dispatch on Google Maps, invoicing, job profitability reporting, an Anthropic-powered reporting assistant, and tiered Stripe subscriptions.
• •Took it to market and first paying subscribers, diagnosed and fixed the first live billing incident, and wrote the release QA checklist that has gated every release since.

Pet wellness e-commerce startup on headless Shopify. Live at animalia.market, pre-launch.

• •Built the storefront from zero as the only engineer, turning a raw supplier catalog into a working store: typed domain layer over the Shopify Storefront, Cart, and Admin APIs (33 GraphQL operations).
• •Wrote a revenue-weighted merchandising engine (deterministic, no LLM at render time) and an AI product photography pipeline that generates brand-constrained images and writes them back to the catalog.

Enterprise learning platform, delivered and invoiced. companychallenges.com

• •Built and delivered the entire platform solo, designing the content model so a challenge is authored once and runs across any number of cohorts without duplicating content.
• •Traced a production query failure to a PostgREST regression from a Supabase upgrade and shipped the fix within hours.

Church discipleship platform on multi-tenant Postgres.

• •Worked across a multi-tenant Postgres platform where each congregation’s data is isolated through row-level security (200+ policies).
• •Built sermon and study authoring on TipTap with scripture insertion, shipping through CI that runs lint, typecheck, build, and Playwright smoke tests on every push.

AI creative platform with a paid credit system. In market and generating revenue.

• •Built the platform to launch and first revenue: multi-studio AI generation on fal.ai with Stripe subscriptions and a paid credit system, on Next.js 15 and Supabase.
• •Designed the billing core: an atomic SQL credit ledger that cannot go negative under concurrent spend, escrowed credits refunded automatically when a model fails, and idempotent webhooks that survive replay.

Privacy-focused AI relationship companion startup, built solo to investor-demo stage.

• •Built the entire product alone in three months (98 API routes, 38 migrations) and carried it to investor-demo stage.
• •Designed the privacy architecture the product depends on: dual-store memory across Postgres and Pinecone with ownership-scoped retrieval, so two partners sharing one companion can never read each other’s entries, plus an operator console where a human approves every AI-drafted message.
