Built with Next.js, Tailwind CSS & Prisma

    Capabilities

    What I can build for you

    A breakdown of skills across web development, AI engineering, and growth marketing — with links to live proof.

    Web Development

    Next.js App Router (full-stack)

    Production apps with SSR, ISR, server actions, and the full App Router — from routing to deployment.

    React + TypeScript

    Strictly typed component architecture, custom hooks, context, and performance-optimized rendering patterns.

    Tailwind CSS + Design Systems

    Scalable design tokens, consistent component libraries, and pixel-perfect responsive UIs from scratch.

    Prisma ORM + PostgreSQL

    Schema design, complex queries, migrations, and relational modeling for production databases.

    API Development (REST, GraphQL, OpenAPI)

    Well-documented, versioned APIs with proper auth, rate limiting, validation, and OpenAPI specs.

    tRPC (type-safe APIs)

    End-to-end type-safe API layers with zero schema duplication between client and server.

    Authentication (NextAuth, Clerk)

    Full auth flows — OAuth, magic links, sessions, JWTs, role-based access, and multi-tenant support.

    Stripe Payments & Billing

    Subscriptions, one-time payments, webhooks, metered billing, and customer portal integrations.

    Edge / Serverless functions

    Globally distributed compute with Vercel Edge, Cloudflare Workers, and cold-start optimized lambdas.

    Redis caching & queues

    Cache strategies, job queues (BullMQ), pub/sub, and rate limiting to handle high-throughput workloads.

    WebSockets / real-time

    Live dashboards, chat, collaborative features, and streaming UIs using WebSockets and SSE.

    Docker + CI/CD pipelines

    Containerized apps, multi-stage builds, GitHub Actions workflows, and automated test/deploy pipelines.

    AWS S3 / Cloudflare / Vercel

    Object storage, CDN configuration, edge caching, and infrastructure-as-code for scalable deployments.

    Testing (Vitest, Playwright, Jest)

    Unit, integration, and E2E test suites with CI enforcement, coverage thresholds, and typed mocks.

    Monorepo architecture (Turborepo, pnpm)

    Shared packages, incremental builds, and workspace tooling for large codebases with multiple apps.

    AI Development

    OpenAI (all models — GPT, o1, o3, Realtime)

    Chat completions, function calling, structured outputs, assistants, and the Realtime API for voice and streaming.

    Anthropic Claude (all models)

    Claude 3.5/3.7 Sonnet and Opus integrations — extended context, tool use, and vision capabilities.

    Google Gemini (all models)

    Gemini 1.5/2.0 Flash and Pro — multimodal inputs, long context, and native Google ecosystem integrations.

    AI Agents & Tool Use

    Multi-step autonomous agents with tool calling, memory, planning loops, and human-in-the-loop checkpoints.

    RAG (Retrieval-Augmented Generation)

    Full RAG pipelines — chunking, embedding, retrieval, reranking, and grounded response generation.

    Embedding & semantic search

    High-performance vector search with cosine similarity, hybrid search, and metadata filtering at scale.

    Prompt engineering & evals

    Systematic prompt design, chain-of-thought, few-shot patterns, and automated eval frameworks.

    Multimodal AI (vision, audio, documents)

    Image analysis, document parsing, audio transcription, and mixed-modality pipelines across providers.

    AI Voice & TTS (WebSockets, Realtime API)

    Low-latency voice applications using OpenAI Realtime API, WebSocket streaming, and speech synthesis.

    AI Streaming (SSE, streaming responses)

    Token-by-token streaming UIs, server-sent events, and backpressure-aware streaming architectures.

    Vector databases (Pinecone, pgvector)

    Index management, namespace isolation, upsert pipelines, and ANN search for production RAG systems.

    LangChain / LlamaIndex pipelines

    Composable LLM pipelines, document loaders, retrievers, and chain abstractions for complex workflows.

    Model Context Protocol (MCP)

    Building and consuming MCP servers to give AI agents structured access to tools, data, and APIs.

    AI-powered automations (n8n, Zapier)

    No-code/low-code automation workflows with LLM nodes for classification, extraction, and generation.

    Fine-tuning (LoRA, PEFT)

    Domain adaptation of open-source models using LoRA and PEFT techniques on custom datasets.

    Image generation (DALL-E, Stable Diffusion)

    Programmatic image creation, variation, and editing pipelines for product, marketing, and content use cases.

    Growth Marketing

    GA4 + GTM implementation

    Full analytics setup — event schemas, custom dimensions, conversion tracking, and data layer architecture.

    Marketing attribution modeling

    Multi-touch attribution, assisted conversion analysis, and channel ROI reporting across the funnel.

    SEO strategy & technical SEO

    Core Web Vitals, structured data, crawl optimization, content gap analysis, and programmatic SEO.

    Content strategy & creation

    Editorial calendars, SEO-led content briefs, long-form articles, and AI-assisted content workflows.

    Email automation (Klaviyo, Mailchimp)

    Lifecycle flows, segmented campaigns, A/B tests, and behavioral trigger sequences for retention.

    Paid search & social campaigns

    Google Ads and Meta campaign setup, audience building, bidding strategies, and performance reporting.

    CRO & A/B experimentation

    Hypothesis-driven tests, statistical significance analysis, and iteration loops to lift conversion rates.

    UTM tracking & campaign QA

    Consistent UTM taxonomy, tagging audits, and real-time dashboards to keep attribution clean.

    Analytics dashboards (Looker, Metabase)

    Self-serve BI dashboards with live data connections, drill-downs, and automated report delivery.
