You will get a practical AI/RAG integration plan for your SaaS product
Top Rated
Project details
I will help you design a practical AI/RAG feature for an existing Rails or SaaS product. This project is for teams that want semantic search, document Q&A, AI-assisted workflows, embeddings, pgvector, OpenAI, Claude, Amazon Bedrock, or API-level AI features, but need a clear technical plan before implementation.\n\nYou will get a production-minded architecture recommendation: data and retrieval strategy, model/provider tradeoffs, database/storage notes, privacy and permission risks, integration points, first milestone, and a prioritized roadmap. My focus is not hype or demos; it is the smallest practical plan that can be built, tested, and maintained inside a real product.

Job Success
Athens, Greece - 7:50 am local time
I have 16 years of Rails experience and 20 years building software products across SaaS, marketplaces, healthcare, payments, real estate, booking systems, and internal tools. I am most useful when a project needs senior ownership: someone who can join an existing codebase, understand the product, make practical technical decisions, and ship production work without heavy supervision.
What I can help with:
- New Rails features and full product workflows
- Rails API design, integrations, and backend architecture
- PostgreSQL, Redis, Sidekiq, Hotwire/Turbo, Stimulus, React, React Native
- AWS-backed infrastructure and integrations, including Amazon Bedrock where it fits the product
- Stripe payments, marketplace flows, booking systems, and admin tools
- Performance work, production debugging, and legacy code cleanup
- Role-based permissions and internal operations workflows
- AI/RAG features inside existing products: embeddings, pgvector, semantic search, AWS Bedrock, Claude, OpenAI, and LLM workflows
Recent work:
- Led engineering for a Rails real estate marketplace, covering architecture, delivery, and production decisions.
- Built workflow automation and granular role-based permissions for internal operations.
- Scaled a high-traffic Ruby service from 50k to 150k requests/minute ahead of Black Friday by tuning ActiveRecord pooling and rewriting hot-path queries.
- Built booking and mobile product flows across a Rails API, Redis-backed scheduling, React Native, and Stripe.
- Built natural-language search over HTA documents using embeddings, pgvector, structured filters, and a RAG service.
I care about simple architecture, clear communication, small deliverables, reliable deployments, and code that is easy to maintain after the first release. If you need a senior Rails engineer who can own a feature end-to-end, stabilize a production app, or help a small team move faster, I am a good fit.

Review goals and data sources
I review the use case, current stack, documents/data, privacy constraints, and success criteria.
Map RAG architecture
I outline retrieval, embeddings, model/provider choice, storage, permissions, and API boundaries.
