Capabilities
One team for the whole stack.
Most clients arrive with a single problem and stay for the rest. Design, engineering, infrastructure and the operations after launch sit under one roof — and one accountable partner.
Enterprise Systems
02ERP, billing, asset and dashboard systems that carry regulated workloads. Role-based access, audit trails, integration with the legacy estate you cannot switch off.
- PostgreSQL
- Node
- Go
- REST & GraphQL
Mobile Applications
03Cross-platform apps from first commit to store release — Flutter and React Native, with the release engineering and store pipelines that keep shipping weekly.
- Flutter
- React Native
- iOS
- Android
AI & Automation
04Practical machine intelligence: computer-vision features, LLM assistants and retrieval pipelines wired into products people already use.
- Vision
- LLM
- RAG
- Pipelines
Cloud & Reliability
05Infrastructure as code, CI/CD, observability and on-call runbooks. Deployments that are boring on purpose.
- AWS
- GCP
- Cloudflare
- Docker
In-house products
We ship our own software, too.
Client work funds it; product work sharpens it. Every pattern we sell has already survived our own production traffic.

VeilKey
A zero-knowledge vault for credentials and secrets. Everything is encrypted in the browser before it leaves the device — the server holds ciphertext it cannot read.

How we work
Four phases. No theatre.
The same sequence for a national utility and a seed-stage product. It is unglamorous, and it is why estimates hold.
- I
Discover
One week, senior only. We map the domain, the constraints and the integrations, and write down what success measures look like before anyone opens an editor.
Scope, risks, fixed estimate
- II
Architect
Data model, service boundaries, auth, environments and the release path. Decisions are documented so the third engineer to join reads the same story as the first.
Architecture & delivery plan
- III
Build
Two-week increments against a staging URL you can open any day. Code review on every change, tests where they earn their keep, no surprise at the demo.
Shippable increments
- IV
Operate
Monitoring, alerting, runbooks and a named engineer who answers. We stay after launch, because launch is when the interesting failures arrive.
SLA, observability, on-call
Four promises we
put in writing.
- Senior hands only
- The engineer in the kick-off is the engineer writing the code. No hand-off to a junior bench.
- You own everything
- Source, infrastructure, credentials and documentation are yours from day one. No lock-in, ever.
- One accountable partner
- A single point of ownership across design, engineering and operations — one throat to choke.
- Written down
- Architecture decisions, runbooks and handovers in writing. Institutional memory outlives contracts.
CF FENIX · Founder
From the founder
“We do not sell hours. We take responsibility for the outcome — the architecture, the release, the uptime at 3 a.m. That is the only reason a national utility or a Swedish software house keeps a partner ten thousand kilometres away.”
Cong Fandi has led web, enterprise-system and mobile engineering for clients on four continents — from Indonesia’s new capital authority and the national electricity utility to product teams in Sweden, the Nordics and the United States.
- Led delivery for Indonesia’s new capital authority (IKN) and PLN’s HARPA platform
- Long-running engineering partner to Abersoft (Sweden), Fika Connects and Nova Circle
- Founder of VeilKey, KickVote and AI Body Builder
- Hands-on across web, enterprise systems, mobile and cloud infrastructure

Engagement models
Three ways to work with us.
Every engagement starts with a conversation and a written scope. No retainer traps, no minimum term beyond the work agreed.
Product Build
Fixed scope
A defined platform, system or app taken from discovery to production release.
- Discovery & architecture
- Design + engineering
- Launch & handover
- 90-day warranty
Embedded Team
Monthly retainer
A senior squad inside your workflow — your board, your standups, our delivery discipline.
- 2–6 senior engineers
- Your tooling & rituals
- Fortnightly increments
- Named tech lead
Rescue & Scale
Assessment first
For a build that stalled or a system straining under load. Audit, stabilise, then accelerate.
- Codebase & infra audit
- Stabilisation sprint
- Performance & cost work
- Roadmap to hand back
Questions
Answered plainly.
The things prospective clients ask before the first call.
How do you work with clients in Europe and the US?
We run on GMT+7, which overlaps European mornings and US evenings. Every engagement has a written communication contract: async by default in your own tooling, a fixed weekly call, and a named engineer who answers within one business day. Ten-plus international clients have run this way for years.
Who actually writes the code?
Senior engineers, led by the founder. The person who scopes your project stays on it. We do not staff a project with juniors after the sales call.
What happens to the code and infrastructure?
It is yours from the first commit. Repositories live in your organisation, cloud accounts are in your name, and handover includes architecture notes and runbooks. Leaving us should cost you nothing but the goodbye.
Can you take over a project someone else started?
Yes — that is our Rescue & Scale engagement. We begin with a paid audit of the codebase, infrastructure and delivery process, then give you an honest assessment: stabilise, refactor, or rebuild. Sometimes the honest answer is that you do not need us.
How quickly can you start?
Discovery usually starts within two weeks. Full squads need three to four weeks of notice. Urgent production incidents on existing systems are handled immediately.

Tell us what you
need built.
You will hear back from a senior engineer — not a sales desk — within one business day, with an honest read on scope, timeline and whether we are the right partner at all.
