Performance tuning for critical FinTech systems

Make slow workflows faster and steadier before a rewrite becomes the only plan.

Your core services now handle more trading activity, payment volume, reports, and background jobs than before. We help FinTech, trading, and banking teams fix one painful workflow at a time — focused on latency, throughput, and memory pressure at the software and system level.

What this looks like in practice

The symptoms start showing up outside engineering.

Slow user actions, support noise, late reports, delayed jobs, restarts, higher cloud bills. For a CTO, it becomes a business problem: senior engineers pulled off the roadmap, customer trust suffers.

  • Order-related work crawling near New York market open
  • Payment processing buckling under peak load
  • Long reports, slow APIs, overloaded queues and jobs
  • Memory growth, restarts, occasional crashes under load
  • Cloud spend climbing faster than usage
  • Recent performance incidents that nobody owns

The rule stays simple.

Your workflow may differ. It must matter to users, revenue, risk, or daily operations.

If it does, we can scope it. Common examples include order-related work near New York market open, payment processing under peak load, long reports, slow APIs, queues, and background jobs.

How we work

One workflow. Clear target. Real evidence.

We pick one critical workflow with your team and agree on the target before the audit starts. Then our analyst and technical lead inspect the evidence and bring back a concrete answer.

01

Pick one workflow

Together we choose the workflow that hurts most, then agree on the terms before any work starts.

  • current symptoms
  • business impact
  • technical metrics
  • access rules & risk limits
  • production boundaries & test window
02

Inspect the evidence

Our analyst and technical lead look at what actually runs in production — not slideware.

  • code paths
  • database queries, indexes, access patterns
  • logs, traces, and metrics
  • API & service behavior
  • queues, schedulers, background jobs
  • memory growth, restarts, incident history
03

Deliver a clear answer

You get one of three outcomes — concrete, measured, and tied to the agreed target. No vague advice.

  • short-cycle fix you can ship
  • phased plan with controlled steps
  • no-go answer — no fee
You get a clear answer in 2 to 3 weeks. If we propose a short-cycle fix, it typically fits inside up to 4 weeks of build or test time — with rollback, monitoring, and production boundaries written down.
What you get

One of three outcomes — never a broad audit dressed as findings.

Every engagement ends in a concrete answer that ties back to the target you agreed on at the start.

Outcome 1

A short-cycle fix

A concrete change that fits the agreed target and can be built or tested, often in up to 4 weeks. Tied to code, metrics, and a measurable target — with rollback and monitoring.

Outcome 2

A phased repair plan

The issue is real, but the right fix needs several controlled steps. We document the sequence, dependencies, risk limits, and what each step buys you.

Outcome 3

A no-go answer

No safe, measurable fix found inside the agreed scope. We tell you that plainly — and you owe no fee. Time you don't spend chasing the wrong fix is time saved.

How payment works

You do not pay for a broad audit or vague advice.

Gehtsoft USA charges only after we find a credible short-cycle fix that matches the terms set upfront. Your team reviews the proposal with us before any fee starts.

A credible fix must:

Every short-cycle proposal is held to the same standard.

  • Match the agreed business goal
  • Connect to code, metrics, logs, traces, database behavior, runtime behavior, or memory data
  • Have a measurable target
  • Include expected impact, work size, and risk
  • Fit the agreed build or test window
  • Include rollback, monitoring, and production boundaries

Then you choose the next step.

Gehtsoft USA builds the fix with you, or your team builds it from our plan. Either way, the scope and the metrics are already agreed.

No black box. No rewrite-first pitch. No fee without a credible short-cycle fix. If we cannot find one safely, we tell you — and we walk away.

Why trust Gehtsoft

We keep the work narrow. One workflow. Clear metrics. Clear risk limits.

Twenty-five-plus years of production software work behind a small, focused engagement.

Production-grade discipline

Our software has served 5M+ end users. We have worked with financial services, regulated projects, and applications tied to the NYSE — and we treat your production with the same care.

Software-level focus

Latency, throughput, and memory pressure at the software and system level. That is the layer where a careful engineer still moves the needle the most.

Evidence, not opinion

Every claim ties back to code paths, traces, queries, runtime behavior, or memory data. If we cannot show the evidence, we do not put it in the proposal.

What we do not sell.

Network tuning, routing, hardware, cloud provider issues, and external infrastructure sit outside this service. We document those findings and point them to the right owner — we don't pretend to be that owner.

Best fit

For growing FinTech, Trading, and Banking teams that see any of these.

If one or more of these is on your status page or in your weekly review, there is a workflow worth scoping.

FAQ

Common questions before we start

The honest answers we give every CTO before the first call.

What if you find nothing fixable inside the agreed scope?

Then we say so. That is the no-go answer — and there is no fee. We would rather tell you the truth than ship a fix that doesn't reproduce the target in production. You keep the time and the relationship.

How is this different from a generic performance audit?

A broad audit reports findings. We commit to one workflow with a target you agree to upfront. Every proposed change is tied to code, metrics, or runtime data, and fits an agreed build or test window — with rollback and monitoring written down.

Will you push for a rewrite?

No. We look for short-cycle fixes first. When a rewrite is genuinely the only safe path, we say so — and structure it as a phased plan with controlled steps, not a year-long migration. Most engagements never get there.

How do you protect production during the work?

Risk limits, access rules, and production boundaries are part of the upfront agreement — before the audit starts. Any change we propose includes rollback, monitoring, and an agreed test or build window.

Does this slow down our current development?

No. We work in parallel with your team, which doesn't require code freezes or roadmap pauses. Our analyst and technical lead inspect production evidence, write up findings, and propose fixes independently; we sync with your team at agreed checkpoints while you keep shipping.

Who actually does the work?

An analyst and a technical lead from Gehtsoft USA, working directly with your team. No black box, no offshore handoffs. After we deliver the proposal, your team chooses: we build the fix with you, or you build it from our plan.

How long until we get a clear answer?

Two to three weeks from the agreed start. If we propose a short-cycle fix, it typically fits inside up to four weeks of build or test time. Phased plans are scoped step by step.

Do you handle network, routing, or cloud infrastructure tuning?

No. Network tuning, routing, hardware, and external infrastructure sit outside this service. If our evidence points there, we document the finding and point it to the right owner.

Start small. Pick one workflow that hurts users or operations.

Gehtsoft USA will help you find out what can be fixed safely first. Tell us a little about the workflow — a senior engineer reads every message.

Typical first reply within one business day. Nothing is shared outside Gehtsoft USA without your written go-ahead.
