INTRODUCE

I Craft The
Digital Landscape

I am a Senior Full Stack Engineer & Engineering Lead with 10+ years building production systems across EU & Asia, currently leading an 8‑engineer team on multi‑tenant platforms in finance and healthcare.

I work the whole stack: Go microservices and SvelteKit, the CI/CD and testing standards around them, and AI engineering, LLM agents with tool‑calling, RAG pipelines, computer vision and forecasting, shipped as evaluated production features rather than demos.

ABOUT ME

About Me

Hi, my name is Radinal Dewantara. I lead engineering teams and still write the hard parts myself. Over 10+ years I have taken systems from an empty repository to production for companies across Europe and Asia.

Most recently: a multi‑tenant finance platform for European SMEs, and a multi‑tenant residential care platform covering resident census, movement pipelines, an event outbox with audit trail and retention, and tenant provisioning. Go microservices behind generated OpenAPI clients, SvelteKit on the front, PostgreSQL underneath. The AI engineering is held to the same bar: LLM agents with tool‑calling, RAG over vector search, computer vision and forecasting, each with evaluation and failure handling before a user ever sees it.

SERVICES

My Services

Product engineering end to end: scalable full‑stack architecture, engineering leadership, DevOps automation and production‑grade AI integration.

01

Full‑Stack Development

Architect and build scalable web and mobile apps using SvelteKit, React.js, Go, Python, Flutter, and cloud‑native services, delivering high‑quality, maintainable code end‑to‑end.

02

Team Leadership & Mentoring

Lead remote teams of up to 8 engineers, establish CI/CD and testing standards, mentor juniors, and align technical strategy with product goals.

03

DevOps & CI/CD

Design and maintain Docker‑based pipelines, GitLab CI/CD workflows, infrastructure‑as‑code, and cloud deployments on AWS & Firebase for zero‑downtime releases.

04

AI Engineering & LLM Integration

Design and ship production AI features: LLM agents with tool‑calling, RAG pipelines over vector search, OpenAI & Anthropic workflows, TensorFlow / computer‑vision models, plus forecasting and anomaly detection, turning model output into reliable, evaluated, user‑facing product capability.

Also Available: Growth & Brand

Offered to consulting clients who would rather have product and go‑to‑market handled by the same person. This half of the practice came first: I started out in brand and online marketing, including brand ambassador work for Cosmic Clothes, before moving into engineering.

05

SEO & SEM

Grow organic and paid visibility: technical SEO audits, on‑page and content optimization, Core Web Vitals, plus Google Ads and Meta campaigns with conversion tracking and ROAS‑focused reporting.

06

Social Media Management

Run social presence end‑to‑end: content calendars, copywriting, scheduling, community engagement and performance analytics across Instagram, TikTok, LinkedIn and Facebook.

07

Branding

Craft distinctive brand identities: logo systems, color and typography, brand guidelines, voice and messaging, a cohesive identity that scales across every touchpoint.

08

Graphic Design

Design that communicates: marketing collateral, social creatives, pitch decks, packaging and UI assets, produced in Figma, Photoshop and Illustrator for print and digital.

SKILLS

My Advantages

Deep expertise across the modern senior engineering stack (SvelteKit, Go, TypeScript, React, Next.js, and cloud‑native infrastructure) combined with hands‑on AI engineering using OpenAI, Anthropic, TensorFlow, RAG and LLM‑agent workflows to ship production‑grade, intelligent products.
