For Fleet Management & Mobility SaaS

Your system is the reason your business is slow.

We cut 30% off cloud bills and stop 3 AM production pages for Fleet Management and Mobility SaaS teams — by fixing the Kafka, event-driven, and OEM integration issues we've spent years solving at scale in automotive production systems. Backed by 7 years of aerospace engineering reliability mindset.

The problem

Does any of this
sound familiar?

Features take weeks, not days Every new feature touches a dozen services. Developers are afraid to change anything. The roadmap keeps slipping.
AWS bill doubled and nobody knows why Costs grow without a clear reason. No one wants to touch the infrastructure that's "working."
Production incidents at 3 AM Your team finds out about problems from customers, not from monitoring. There's no real observability.
New integration breaks everything Adding a new vendor or payment system requires touching 15 services and praying nothing breaks.
Engineers spend more time firefighting than building Your best engineers are stuck in incident response instead of working on what actually matters.
// what we do about it

These aren't talent problems. They're system problems that cost your business money every day they go unfixed.

We find the exact 2–3 decisions that are blocking you, give you a written plan with business impact estimates, and fix them — while your product keeps shipping.

No long silences. No surprise scope creep. Every sprint moves a business metric.

Who this is for

We work with a
specific kind of team.

Astoryx isn't a generalist dev shop. We pick engagements where our Kafka, event-driven, and Mobility background makes a measurable difference — and we say no to the rest. Better for you, better for us.

Strong fit
You run a Fleet Management, Connected Vehicles, Mobility, or IoT SaaS backend.
Your engineering team is 15–80 people. Product is 3+ years old.
Kafka or another event bus is load-bearing in your architecture.
Your cloud bill is growing faster than your user base.
You need to integrate a new OEM, telematics vendor, or partner API without destabilizing production.
Not a fit
You need someone to start Monday with zero technical discovery.
You're comparing us to offshore dev shops on $20/hour rates.
You want to build a generic CRUD app or marketing site.
You're looking for someone to close tickets by the hour without owning outcomes.
What we do

Three ways we can
work together

01
Backend Cost & Risk Diagnostic
Find $50–200K/year you're leaving on the table — before your cloud bill doubles again. Two-week deep audit of your Java/Kafka backend: codebase review, infrastructure analysis, engineer interviews. You get a 20-page report with ranked findings, quantified savings, and a 90-day action plan your CTO can sign off on. Money-back if identified savings < $50K annually.
$4,000 fixed
2 weeks
02
Fleet & Mobility System Fixes
Fix broken OEM integrations, harden Kafka consumers, rebuild telemetry pipelines — without pulling senior engineers off your roadmap. Fixed-scope, fixed-price delivery. Typical engagements: consumer group redesign, reactive service extraction, DLQ strategy, async refactoring. Proven patterns from years of high-volume vehicle telemetry production work.
from $15,000
4–8 weeks
03
Engineering Velocity Partner
Ship 30% more features per quarter — without adding engineering headcount. Fractional Staff Engineer retainer: we join your architecture decisions, review critical PRs, unblock integration work, and mentor your senior engineers. Best for teams stuck between "needs Staff Engineer" and "can't afford another hire."
from $8,000 / mo

How we work

No handoff gaps.
Full ownership, start to finish.

01
Discovery Call
30 min. We listen first. You describe what's broken — we ask the questions your team stopped asking months ago.
02
System Audit
2 weeks, fixed price. We map every bottleneck, quantify the cost, and deliver a written action plan with priorities.
03
Phased Delivery
Sprint by sprint. Each sprint targets one business metric. No big-bang rewrites. Production keeps running.
04
Measure & Retain
Monthly before/after metrics. Knowledge transfer to your team. We stay on retainer to protect the gains.
Patterns we solve

Problems we fix.
Outcomes we target.

Representative patterns drawn from production engagements we've delivered at scale in high-volume Mobility backends. Named client references available under NDA after Discovery Call.

Infrastructure costs
Kafka consumers silently reprocessing events in loops. Cloud bill climbing $10–15K/month faster than user base. Engineers afraid to touch the pipeline.
−28%
typical cloud cost reduction after consumer group redesign, idempotency layer, and DLQ strategy. ROI usually in first month.
Delivery speed
Every feature touches a dozen services. Developers afraid to change anything. Roadmap slipping by weeks. OEM integrations delayed 2 quarters.
deploy frequency recovered within 90 days. 3 AM alerts stopped. Team velocity returns to where it should be.
System reliability
Production incidents discovered by customers, not by monitoring. On-call rotation burning out the team. Reconciliation jobs as band-aids everywhere.
−90%
on-call pages eliminated after observability rebuild and root-cause fixes. Team sleeps again. Reconciliation becomes exception, not routine.

Representative engagements

What changes when
the system stops blocking

Narrative scenarios drawn from real production engagements our core team has delivered at scale. Specifics anonymized — detailed case studies and direct references available under NDA after Discovery Call.

01
Features that should have taken days were taking weeks — every change rippled through a dozen tightly coupled services. After a two-week architecture diagnostic, the team had a clear 90-day roadmap. Three months in: deploy frequency tripled, on-call rotation went quiet, feature velocity returned to where it should have been.

Mobility SaaS engagement
Engineering Manager perspective · EU mid-market
// outcome
deploy frequency within 3 months of engagement start
02
Cloud bill was climbing $10–15K per month faster than the user base — no one could explain why. Root cause identified in week one of the diagnostic: Kafka consumers reprocessing events in silent loops after deploys, missing idempotency, inefficient DLQ topology. Fixed in two focused sprints. ROI realized within the first month.
02
Fleet platform engagement
CTO perspective · High-volume telemetry backend
// outcome
−28%
cloud cost reduction, ROI realized in the first month
03
A seven-year-old legacy system with documentation fragments scattered across three tools and tribal knowledge locked in two senior engineers' heads. Within a week we mapped the critical event flows, identified the two architectural decisions blocking velocity, and delivered a written plan with ranked priorities. No wasted time. No vague "let's refactor everything."

Now
Astoryx Software
Boutique engineering firm for Fleet Management, Connected Vehicles, and Mobility SaaS. Led by senior engineers, delivered with a vetted bench of European and Ukrainian specialists. We take engagements where production reliability is the product.
01
We don't learn on your system
Our team runs 100M+ event/day pipelines in production across global automotive platforms. When we touch your architecture, we already know what breaks at scale — before it breaks for you.
02
We sell outcomes, not hours
We're not closing tickets. We're solving the root cause that's costing you speed, money, or reliability. Every engagement is scoped around a measurable business result — not a sprint backlog. Our Backend Diagnostic comes with a money-back guarantee if identified savings fall below $50K annually.
03
Failure modes first, features second
Most teams build features and discover failure modes in production. We design around failure first — then ship fast. A different order of operations. Systems that hold up under pressure aren't an accident.
04
We choose clients, not projects
Two active engagements at a time, maximum. We say no to bad fits. That selectivity means the teams we work with get full attention — not divided bandwidth across a stack of concurrent accounts.
Common questions

What people ask
before they book

Still not sure? These are the questions every client asks before they reach out.

Do you work with teams that already have engineers? +
Yes — that's the typical setup. We come in as a senior external expert alongside your existing team. We own architecture decisions and complex implementation. Your team owns the product long-term and grows stronger through the engagement.
How long is a typical engagement? +
The Backend Cost & Risk Diagnostic is 2 weeks, fixed scope. Project engagements run 4–8 weeks, fixed scope. The Engineering Velocity Partner retainer runs 6 months minimum — legacy migrations and reliability work done properly take time. Clients who want it "done quickly and cheaply" are usually not the right fit.
Can we start with a small paid trial first? +
Absolutely. Most clients start with a Backend Cost & Risk Diagnostic — $4,000 fixed price, 2 weeks. You get a written deliverable with findings, priorities, and effort estimates. Money-back guarantee if identified savings fall below $50K annually. You see exactly how we work before any longer commitment.
How do you measure success in an engagement? +
We agree on 2–3 concrete business metrics before we start: deploy frequency, infrastructure cost, incident rate, time-to-feature. Every sprint has a measurable before/after. If we can't define what success looks like, we don't take the engagement.
Who is this NOT for? +
Companies looking for a developer to close tasks by the hour. We work with clients who want the underlying system problem solved — not just the next sprint unblocked. If you want "cheap and fast," we're not the right fit.
