What I Offer

Full-Stack Web Development

Full-Stack Web Development

End-to-end web platforms for real businesses: customer-facing apps, admin consoles, member portals, and campaign tooling, built with modern TypeScript stacks and production-ready data layers.

  • Next.js & React applications: SPAs and full-stack apps with strong typing, server components where it helps, and Tailwind for fast, consistent UI.

  • Admin & operations dashboards: Back-office tools for campaigns, compliance, member records, attendance, and day-to-day operations.

  • Auth, roles & self-service: Secure sign-in, role-based access, QR check-in, digital IDs, and flows your users can run without support tickets.

  • PostgreSQL & Drizzle ORM: Relational schemas, migrations, and queries designed for correctness, reporting, and long-term maintainability.

  • Marketing & content sites: Fast, content-first sites (including Astro) when the goal is leads, storytelling, and minimal client runtime.

APIs & Backend Systems

APIs & Backend Systems

Reliable backends and integrations behind your product: REST APIs, caching, third-party data sources, and infrastructure shaped for latency and scale.

  • REST & edge-friendly APIs: Documented HTTP APIs with clear contracts, including public data products consumed at the edge.

  • Third-party integrations: Government and vendor APIs (e.g. tax/identity lookups), webhooks, and validation pipelines wired into your domain logic.

  • Caching & performance: Redis and similar layers to keep hot paths fast under real traffic.

  • Data modeling & storage: PostgreSQL, Turso/SQLite at the edge, and schema design aligned with how the product actually behaves.

  • Deployment-ready architecture: Services structured for observability, environment separation, and safe iteration in production.

AI-Integrated Software

AI-Integrated Software

Features and tools that put AI to work without the hype: transcription, summarisation, codegen helpers, and offline pipelines where privacy or cost matter.

  • Real-time speech & translation: Live sessions, audience sharing, and post-session summaries built around streaming audio workflows.

  • LLM-powered developer tooling: CLIs and automations that turn repo context (diffs, commits) into usable output with pluggable model backends.

  • On-device & local inference: Whisper-style transcription and similar workloads that stay on the user’s machine when data sensitivity matters.

  • Product-facing AI features: Summaries, insights, and assistive flows embedded in the app, not bolted on as a demo.

  • Pragmatic model integration: OpenAI, Gemini, Ollama, and others chosen per use case for quality, cost, and deployment constraints.
