Seniortechnology.Executionwithoutfriction.
A network of senior IT professionals. We help companies scale their teams, modernise their technology and deliver complex projects with quality, speed and commitment.
Engineering that solves, rather than promises.
At Halyard Network we combine technical seniority, methodology and distributed talent to accompany companies through their technology challenges.
We work as a flexible network of experts: without the rigidity of large consultancies, without the limitations of isolated freelancers. We assemble the right team for the right moment, with the agility of a boutique and the seriousness of an established firm.
Our clients are growing startups, established scale-ups and traditional companies going through modernisation. We work with them as partners, not as vendors.
How we work with you.
Four collaboration models designed to adapt to the moment and real needs of each company. Pick the one that fits or combine several as things evolve.

Fast integration, clear and frequent communication. Modern tools with integrated AI to deliver faster.
We support
Orderly handover, living documentation, internal team training. Available for the continuous evolution of the system.

Payments, digital banking, insurance.
B2B SaaS
Software platforms for enterprises.
E-commerce
E-commerce at scale.

Four reasons. Nothing more.
Senior profiles only
We don't send junior engineers to learn on your project. Everyone in our network has at least 5 years of contrasted production experience.
No middlemen
You speak directly with the people doing the work. No account managers translating requirements, no management layers inflating costs.
Real flexibility
We adapt the collaboration model to your real needs, not the other way around. Team extension, fixed-scope project, fractional leadership, or hybrid model.
AI as a multiplier
Modern AI-assisted development tools integrated into our workflow. We deliver faster and with higher quality, without compromising robustness or maintainability.
Work in production.
A selection of projects delivered to production for clients across different sectors. Cases anonymised under confidentiality agreements.
Travel bookings marketplace
Architecture refactor to solve hot partitions in the bookings pipeline. Dynamic partitioning design and consumer rework. Sustained throughput at 5x the previous volume, contention eliminated at peak hours.
Telecommunications operator
Design of idempotency mechanisms and DLQ (dead letter queue) in SIM activation pipeline. 90% reduction in manual interventions for failed messages, duplicates eliminated.
Digital banking, regulated system
Implementation of the Transactional Outbox pattern for consistency between database and event publishing in a regulated employment verification system integrated with Social Security. Zero event losses, complete audit trail.
What those who already workedwith us say.
The Halyard team came in to solve a critical bottleneck in our event pipeline. Within three weeks the problem was fixed and our in-house engineers were trained to maintain it. Very different from other consultancies we've worked with.
Hiring seniority by project without the friction of recruiting ourselves. With Halyard we had a senior architect embedded in the team in less than a week. Zero time wasted on endless briefings.
They brought an external perspective that made us question assumptions we had accepted internally. The result was a more pragmatic architecture migration with lower risk than what we had planned.
