Who we are

Senior backend engineers who keep your system up as you grow

FusionHit works as a backend development company for US product teams, staffed with senior engineers across Latin America.

They join your repo, your standups, and your release cadence, so the system carrying your traffic is owned by people you talk to every day.

WHAT WE DELIVER

Backend development services we deliver

The server-side work US product teams hand us most, staffed with senior engineers only.

Custom backend development

Server-side applications for web and mobile products, architected for the load you expect two years out.

API development

REST and GraphQL APIs with the versioning and documentation your other teams can build against without guessing.

Third-party integrations

Payments, CRMs, and ERPs wired into your product with the retry and error handling that keeps data flowing when a provider goes down.

Microservices architecture

Monoliths split along clear domain boundaries, or new systems built that way from day one, so your teams deploy without waiting on each other.

Database design

Relational and NoSQL models (PostgreSQL, MySQL, MongoDB, Redis) tuned for query performance and safe migrations as your data grows.

Legacy backend modernization

Aging services refactored or replaced in stages, with the current system running throughout, so your roadmap never stops.

RELIABILITY

Backends that hold up when traffic does

Three things a backend gets judged on, and how we build for each.

Performance under load

Query tuning, caching layers, and async processing, validated with load tests before every release.

Scale without rewrites

Architecture sized for your growth curve, with stateless services and horizontal scaling, so handling 10x traffic is a configuration change.

Security by default

Role-based access, encryption in transit and at rest, secrets kept out of the repo, and dependency scanning in every pipeline.

HOW WE ENGAGE

Three ways to add backend engineers to your team

Staff augmentation

Senior backend engineers added to your existing team, under your direction, in days rather than months.

Dedicated development teams

A stable backend team working only on your product, self-organizing sprint after sprint while you set the roadmap.

Full project outsourcing

You hand over the scope and we deliver it under our management, covering architecture, development, QA, and maintenance.

OUR PROCESS

How a backend engagement starts

01

Discovery call

Your goals, your current architecture, and where it strains (30 minutes).

02

Team proposal

Matched backend engineer profiles in days, not weeks.

03

Interviews

You meet and approve every engineer.

04

Sprint delivery

Your tools, your workflow, live demos every sprint.

FAQ

FAQs about our backend development services

01

How much do backend development services cost?
Senior nearshore backend rates run 30-50% below equivalent US salaries and agency fees. What you pay depends on team size, seniority mix, and engagement model. You get a transparent, line-item estimate on the first call, with no recruiting fees and no hidden overhead.
02

Can you work on our existing backend, or only on new builds?
Both, and most engagements start with a system already in production. We read the code, map the architecture, and ship inside your existing repo and release process. Greenfield builds follow the same setup, without the archaeology.
03

How do you decide between a monolith and microservices?
By your team size, your deployment cadence, and where the current system actually slows down. Splitting a monolith that works is often the wrong first move, and we will tell you when that is the case. When services are the right call, we split by domain boundary and migrate in stages, never in a single release.
04

How fast can backend engineers start?
We present matched profiles within days, you interview and approve them, and most engineers onboard in under 2 weeks. A US backend hire typically takes 3 to 6 months from job post to first commit.
05

Which backend languages and frameworks do you work with?
Node.js, Python, Java, .NET, Go, PHP, and Ruby, with PostgreSQL, MySQL, MongoDB, and Redis on the data side, deployed on AWS, Azure, or Google Cloud. We staff for the stack you already run.
06

How much time zone overlap will we have?
Our engineers work across Latin America on US Central and Eastern time, which gives 6-8 hours of daily overlap. Backend work benefits from that overlap more than most: architecture calls, incident response, and code review all move faster when both sides are online at once.
07

How do you handle security and data protection?
Role-based access to code and environments, encryption in transit and at rest, secrets kept out of the repository, and dependency scanning in the pipeline. For regulated products we work to your compliance framework (HIPAA, PCI DSS, SOC 2) and follow your audit requirements.
08

Who owns architecture decisions, your team or ours?
Yours. Our engineers bring the options and the trade-offs with a clear recommendation, and your CTO or architect signs off. On teams without a dedicated architect we take the lead on the design and document every decision, so you can review the reasoning later.
09

Do you cover DevOps and deployment, or only application code?
Our backend engineers own CI/CD, environments, and observability for the services they build. If you need a broader platform effort, such as a cloud migration or a full DevOps practice, our specialists pick that up: DevOps services
10

How do you protect our IP and source code?
Every engagement runs on US-friendly contracts, with an NDA in place before the first call and full intellectual property assignment to you. Access to repositories and environments is role-based, and your code stays in your accounts and your cloud, under your control at every stage.
11

Can your engineers work inside our team and tools?
Yes. Slack, Jira, GitHub, your review rules, your definition of done. Our engineers work as teammates inside your systems, with the same access and the same accountability as the rest of your team.
