Surani S.

I build the software companies run their operations on: internal tools, customer portals, AI agents and the automations that tie them together. My clients range from early-stage startups to SaaS companies and enterprise teams. A lot of projects start the same way. Something important lives in a spreadsheet, or in tools that don't talk to each other, or in one person's head, and it's started to slow everyone down. I turn that into a proper app with a real database behind it, usually Supabase or Postgres, and automate the repetitive parts with n8n or Make. How I build depends on what you need. For customer-facing apps I use Next.js or React with TypeScript, on a Python, Node.js or Go backend depending on the job. For internal tools I often use Retool, which I'm certified in up to Platform Architect and Advanced Developer, because it gets a working tool in your team's hands in a fraction of the time a custom front end takes. Some things I've built: - An ERP and a set of labor tracking, purchasing and project tools, all in Retool - The Supabase database and Airtable sync behind a travel company's internal apps, schema designed from scratch with row-level security for several user roles - A sales tool pulling Salesforce, Jira and Slack into one view, which I built on my own - A production AI assistant running Claude and Gemini side by side, built in Next.js with a Python backend. - Nomadic Care, an Australian care-planning platform where clinicians, carers and patients work from one shared care plan. React on the front, Node.js behind it - Frontend and backend work on Oparko, a parking platform used across Scandinavia by operators like Lidl and Securitas (React and TypeScript on Go) A founder I built tools for wrote that I'm "one of the fastest developers we've hired." I think that's mostly because I ask a lot of questions at the start, so there's less to redo at the end. I'm certified by Anthropic on the Claude API and Claude Code, and by Airtable as an Airtable Builder. 10+ years writing software. AI & automation: Claude and OpenAI APIs, Gemini (Vertex AI), AI agents, RAG, OCR and document processing, n8n, Make, Zapier, webhooks, scheduled jobs. Data & backend: Supabase, PostgreSQL, MySQL, MariaDB, MongoDB, Firebase, BigQuery, Snowflake, Redshift, ClickHouse, Airtable, ETL pipelines, data warehousing, REST and GraphQL APIs. Frontend & app: Next.js, React, TypeScript, Node.js, Python, Go, AWS Lambda, Docker. Retool: multi-page apps, custom components, modules, permissions & authentication, workflows, query optimization, staging to production, embedded Retool. Integrations: Stripe, Xero, QuickBooks, Shopify, HubSpot, Salesforce, Jira, Slack, Twilio, Google Workspace, AWS, Elasticsearch, Mixpanel, PostHog, OAuth2. If you've got a spreadsheet that's become the business, or a process you're tired of doing by hand, send it over with a couple of lines about what you want it to do.
