API DEVELOPMENT & INTEGRATION SERVICES

Systems that talk to each other — automatically.

I build the connections your business runs on: documented REST APIs, webhooks that keep systems in sync, and integrations with the platforms you already pay for — so data flows between tools instead of being carried by people.

What disconnected systems cost you

01Manual data transfer

Export the CSV, reformat it, import it somewhere else, repeat tomorrow. Hours of skilled time spent being a human cable between two machines.

02Models nobody can use

A prediction that lives in a notebook helps no one. Served through an API, the same model answers inside your product and workflows.

03Fragile, undocumented hacks

A script someone wrote once, that breaks silently and nobody dares touch. Integrations should be logged, tested and boringly reliable.

04Two versions of the truth

The CRM says one thing, the spreadsheet another. When systems sync automatically, there is one record — and everyone works from it.

What you receive

✓REST API development

Documented, versioned FastAPI endpoints your web, mobile or partner systems can build on — with automatic OpenAPI documentation.

✓Third-party integrations

Payments, messaging, CRMs and AI platforms (including Groq and Gemini APIs) connected into your workflows properly.

✓Webhooks & event sync

Systems that update each other the moment something happens — an order placed, a payment received, a record changed.

✓Data pipelines

Scheduled synchronisation and transformation between systems, with validation so bad data is caught instead of copied.

✓APIs for ML models

Your prediction models served as reliable endpoints any application can call — the bridge from notebook to product.

✓Integration documentation

Endpoints, payloads, error behaviour and credentials handling — written down so the integration outlives its author.

Tools & technologies

FastAPI (Python)

High-performance APIs with validation and documentation generated from the code itself.

REST & JSON

The standard contract between systems — predictable, testable, widely supported.

Webhooks

Event-driven updates between platforms, with signature verification and retry handling.

PostgreSQL & Supabase

The data layer integrations read from and write to, with proper access control.

Groq & Gemini APIs

Production LLM integrations for chat, extraction and document intelligence.

n8n

Where a visual workflow is the right tool, integrations plug straight into automations.

From disconnected to in sync

1

Integration audit

We map your systems, the data each holds, and the events that should move between them. Feasibility is confirmed against real documentation.

2

Contract first

Endpoints, payloads and error behaviour are agreed in writing before code — both sides know exactly what to expect.

3

Build & test

Built against sandboxes where available, tested on success and failure paths alike — including duplicates and timeouts.

4

Deploy & monitor

Deployed with logging and alerts, so the first sign of trouble reaches you before your customers notice.

Straight answers

An API is a standard, secure way for one piece of software to ask another for data or actions — like a waiter between two kitchens. It is what lets your tools work together without anyone copying data by hand.

If a tool offers an API or webhooks — and most serious business tools do — then almost always yes. I check the documentation first and confirm feasibility before quoting anything.

With retries for temporary failures, logging you can inspect, alerts when something breaks, and idempotency — so a repeated message never creates duplicate records.

Yes. All traffic runs over HTTPS, API keys are stored in environment variables rather than in code, and each integration uses the least access it needs to do its job.

It depends on the number of systems and endpoints involved. After a short technical review you receive a written, fixed scope — integrations are quoted on facts, not guesses.
