01.Where teams get stuck

Most teams don't need another deck. They need a senior partner close to the work.

Leadership wants progress, but the real blockers live in code, tools, architecture, team habits, and undocumented tradeoffs. Good consulting turns that mess into decisions, working software, and momentum.

What leaders need

A practical path from technical uncertainty to measurable product improvement.

  • Ship important product work without adding more process
  • Modernize fragile systems while keeping the business moving
  • Improve performance, reliability, and developer velocity
  • Add automation only where it saves real time

What teams are carrying

This is the day-to-day reality many software initiatives inherit.

  • Legacy codebases with unclear ownership and hidden dependencies
  • Product, engineering, and operations pulling on different priorities
  • Slow applications, brittle releases, and observability gaps
  • Important knowledge spread across people, tickets, docs, and chat
  • Roadmaps that need senior technical judgment before they need more hands

Resynapse helps make the path explicit: architecture, performance, modernization, integrations, and pragmatic AI support. The point is to ship useful improvements without pretending the environment is simpler than it is.

02.Consulting focus

Where a small senior consultancy helps.

The shape of the engagement depends on the problem. The common thread is turning technical uncertainty into decisions, working software, and a team that can keep moving after the engagement ends.

01

Architecture needs a clearer path

  • The current system works, but every change feels riskier than it should
  • Technical choices are scattered across teams, services, and old decisions
  • Teams need a pragmatic plan that respects deadlines and existing constraints
02

Performance and reliability are holding growth back

  • Users feel slowness, but the real bottlenecks are not obvious
  • Rendering, data loading, bundle size, and runtime behavior need measured fixes
  • The team needs improvements that stick, not one-off tuning passes
03

The team needs implementation leverage

  • Critical context lives with a few senior people or inside scattered tools
  • Internal workflows depend on manual handoffs that software could simplify
  • AI and automation ideas need product-shaped boundaries before they can ship
03.Services

Consulting, architecture, and implementation help.

Resynapse is set up for focused work: review the system, fix the bottleneck, or stay close while the team makes the calls that matter.

01 /

Architecture review

For teams that need a clear technical direction before they spend another quarter guessing. We look at the product, the code, the constraints, and the tradeoffs.

  • Codebase and architecture review
  • Performance and reliability risks
  • A practical plan for the next move
1–2 weeksBest when the team knows something is off but needs sharper technical judgment.
02 /

Product engineering sprint

Hands-on help for a focused build, migration, or cleanup. Enough scope to make real progress without turning it into a long consulting program.

  • Frontend, full-stack, or internal tool work
  • Modernization of painful parts of the system
  • Implementation support with your team
3–6 weeksBest when there is a concrete product or engineering problem worth fixing now.
03 /

Embedded technical advisory

Ongoing senior help for teams that are already building. Useful for architecture decisions, React and Preact work, performance reviews, and AI features that need sensible boundaries.

  • Architecture and implementation reviews
  • Product and engineering tradeoff calls
  • Coaching for staff engineers and founders
MonthlyBest when the team has momentum and wants a senior outside view before the hard calls.
05.How the work runs

Close to the work, light on ceremony.

The process is simple on purpose. Understand the problem, inspect the system, make a small number of good calls, and help ship the work.

01

Start with the business problem

We pin down what is actually slowing the team down. Sometimes it is architecture. Sometimes it is product scope. Sometimes it is a workflow nobody has written down.

02

Read the system before prescribing fixes

That means code, product behavior, team constraints, release habits, and the weird edge cases people usually skip in kickoff calls.

03

Choose the smallest useful move

The goal is not to redesign everything. We pick the change that removes real friction and gives the team a better next step.

04

Ship with the team

Depending on the engagement, that can mean implementation, review, pairing, technical direction, or helping shape the work so your team can deliver it.

05

Leave the path cleaner

A good engagement should leave behind better decisions, clearer ownership, and software the team can keep improving without me in every meeting.

04.About

You work directly with Jovi De Croock.

Resynapse is Jovi De Croock's consulting practice. Jovi is a Preact core maintainer with deep technical work across frontend architecture, signals, developer tooling, and product implementation. Companies bring him in when they need senior judgment and hands-on execution across architecture, performance, modernization, and product delivery. Not a layered team billing for slideware.

The work usually starts with a business or product bottleneck: a slow UI, an uncertain architecture, a legacy modernization, an internal tool that no longer fits, or an AI idea that needs production boundaries. The job is to make the path clear and help the team ship.

Small consultancy. Senior partner. Practical delivery.

Founder-led from discovery through delivery
Works with existing codebases, teams, tools, and constraints
Bridges product, engineering, and operations without adding theater
Focused on practical software outcomes, not slideware
Start a conversation

Bring the software problem that keeps coming back.

If the team is stuck on architecture, performance, modernization, internal tooling, or an AI feature that needs a real shape, start with a 30-minute call.

Good fit: founders, CTOs, product leaders, staff engineers, and teams that want direct senior help instead of a big consulting process.
