AI & RAG architecture sprint
Design-first engagement for retrieval quality: data sources, chunking, embeddings, reranking, evals, and safety before you commit engineering weeks.
- Problem framing, data sources, evaluation plan
- Chunking, embeddings, reranking, latency budget
- Threat model: prompt injection, PII, access control
- Written architecture + backlog for your team

Build & integrate
FastAPI, Django & microservices
Production Python and Node backends: async APIs, workers, auth, multi-service boundaries — aligned with how WinstaAI and past SaaS backends were built.
- REST / async APIs, Celery jobs, observability hooks
- PostgreSQL, Redis, Mongo, vector stores as needed
- JWT, OAuth, RBAC, WebSockets, GraphQL where fit
- Docker-ready layout, OpenAPI, README, runbooks

Agents & orchestration
Agentic AI & multi-agent systems
Tool-calling agents, multi-model routing, admin and metering patterns for SaaS — the same class of work as production agentic platforms on my CV.
- Agent workflows, planners, tool registries, guardrails
- Multi-model routing, fallbacks, cost controls
- Stripe, PayPal, RunPod, FAL.ai, OpenAI-style APIs
- Pairs with Next.js / React frontends when you need UI

End-to-end product
Full-stack development (React / Next.js)
MVPs and product lanes across dashboard, marketing surfaces, and API integration — TypeScript, Tailwind, SSR/SSG, wired to your Python or Node backend.
- Next.js App Router, React, TypeScript, Tailwind
- Auth flows (Auth0, Firebase, custom JWT) and RBAC-aware UI
- Billing UX hooks to Stripe / PayPal where needed
- SSR, SEO-sensitive pages, performance passes

Automation & integrations
Workflow automation & internal tools
Reliable background processing and glue between systems: queues, webhooks, notifications, and third-party APIs so ops and product move faster with less manual work.
- Celery / async workers, schedules, retries, idempotency
- Webhooks, Twilio, DeepL, payment and AI provider hooks
- Admin tooling, imports/exports, reporting pipelines
- GitHub Actions and release automation patterns

Generative & media AI
Generative AI APIs — speech, vision, images, GPU
Ship features like STT/TTS pipelines, OCR, text-to-image, and hosted GPU inference — similar surface to Dibbly, Paperport, and Winsta-style media stacks.
- Speech-to-text, TTS, transcription, multilingual flows
- OCR, text-to-image (ComfyUI, Replicate), face swap patterns
- RunPod, FAL.ai, Hugging Face, Ollama integrations
- Queues, quotas, and safe rollout behind feature flags

Data & events
Event-driven systems & data pipelines
High-throughput patterns: Kafka-style messaging, CDC, and service boundaries for systems that must scale without losing consistency.
- Apache Kafka, async consumers, backpressure-aware design
- Debezium CDC patterns where applicable
- Service decomposition and contract-first APIs
- Operational playbooks for your SRE or platform team

Cloud & reliability
Cloud, DevOps & platform hardening
Docker and Kubernetes-oriented delivery, CI/CD, Nginx, AWS/GCP primitives, and observability — production paths from years shipping containerized backends.
- Docker, Kubernetes, Nginx, VPS and cloud layouts
- GitHub Actions CI/CD, environments, secrets hygiene
- AWS EC2/S3/Lambda, GCP touchpoints as needed
- Sentry and logging hooks for triage-friendly ops

Healthcare & compliance-aware
Secure backends for regulated domains
Experience from HIPAA-oriented diagnostic reporting (PathHub-style): access control, audit-friendly flows, and careful handling of sensitive data — scoped to your legal requirements.
- Role-based access, session hardening, audit trails
- Secure file and imaging workflows where applicable
- Collaboration with your compliance/legal stakeholders
- Documentation suitable for security review

Rescue & review
Performance, security & cost audit
Short, opinionated review of your AI and backend stack: latency, token spend, GPU vs CPU choices, auth/webhooks/secrets — you get a prioritized fix list.
- Slow RAG paths, redundant LLM calls, caching wins
- Right-size infra and model routing for unit economics
- Security pass: auth, webhooks, secrets, headers
- Optional follow-up implementation milestones
