Should we build on AWS or Firebase?

It depends on the product. Firebase is a strong fit for mobile apps, realtime features, and early-stage products that need managed auth and data out of the box. AWS fits products that need fine-grained control over compute, networking, and data, or that must meet specific compliance requirements. Many of our builds combine the two, and we recommend a platform only after understanding your product, team, and growth plans.

Why hire Codesigma instead of a freelancer or a larger agency?

You get senior engineers with direct access to the people doing the work, without the overhead of a large agency or the single point of failure of a freelancer. Codesigma was founded in 2015 and is founder-led, so the experience behind the proposal is the experience on the project.

How do we start an engagement?

We begin with a conversation about your product and goals, followed by a short discovery phase. For existing systems we review your current AWS or Firebase setup first, so the plan is based on what is actually there. You get a written proposal with scope, approach, and team shape before any commitment.

How do you handle communication across time zones?

You get a single point of contact, regular written updates, and scheduled calls at times that work for you. Decisions and cloud changes are documented so nothing depends on catching someone online.

Who owns the code, the infrastructure, and the accounts?

You do. All code, infrastructure definitions, and documentation are your IP, and we work inside AWS and Firebase accounts that you own from day one. We are NDA-friendly and treat every engagement as confidential by default.

How do you approach cost?

Cloud cost is a design input, not an afterthought. We estimate the cost drivers of a proposed architecture up front, choose services with your budget in mind, and set up billing visibility so there are no surprises. Engagement pricing is scoped per project after discovery, so you pay for what your product actually needs.

How do you approach timelines?

We plan in milestones and give estimates only after discovery, when we understand the real scope. Progress is visible throughout, and if anything threatens a milestone we raise it early with options, rather than reporting it after the fact.

Why hire Codesigma for AWS and Firebase development

Cloud problems rarely announce themselves early. Teams hire AWS developers or Firebase developers, ship a first version quickly, and only later discover runaway costs, security gaps, or an architecture that cannot handle real usage. Codesigma treats cloud work as product engineering: we choose services deliberately, document the architecture, and design for the bill you will actually pay, not just the demo that works today.

AWS and Firebase solve different problems, and knowing when to use which is half the value of hiring well. Firebase gets a product to market fast with managed auth, realtime data, and mobile-friendly tooling; AWS gives you the depth to run serious workloads with fine-grained control over compute, data, and networking. Our team is senior and founder-led, with 10+ years of software experience, and we will tell you honestly which platform fits your product, including when the right answer is both.

We cover the full lifecycle, from idea to development to deployment to support. Whether you need a new backend built from scratch, an existing Firebase project hardened for growth, or an AWS environment untangled and made maintainable, the engagement starts with understanding your goals and ends with infrastructure your team can own and operate with confidence.

What we build with AWS / Firebase

AWS and Firebase are our core cloud platforms across web and mobile products. Typical builds include:

Serverless backends and APIs

Event-driven backends on AWS Lambda and Firebase Cloud Functions with clean API design, typed contracts, and cost-aware architecture.

Realtime applications

Live dashboards, chat, presence, and collaborative features built on Firestore and the Firebase Realtime Database, with sync logic that stays correct under load.

Authentication and user management

Sign-in flows with Firebase Authentication or Amazon Cognito, covering social login, multi-factor auth, and role-based access control.

Mobile app backends

Complete Firebase backends for Flutter and React Native apps: data, auth, push notifications, analytics, and crash reporting wired in from day one.

AWS cloud infrastructure

Production environments on EC2, ECS, RDS, and S3 with infrastructure as code, sensible networking, and monitoring your team can actually read.

Data storage and pipelines

Storage and data-flow design across S3, DynamoDB, RDS, and Firestore, including migrations from one platform to another as products outgrow their first stack.

Why teams hire Codesigma

Senior, founder-led team

Founded in 2015, Codesigma is led by engineers with 10+ years of software experience. Senior people design your cloud architecture and review every change.

Clear, direct communication

You talk to the people doing the work. Plans, trade-offs, and progress are communicated plainly, and cloud decisions are explained before they are made.

Ownership of outcomes

We take responsibility for the result, not just the tickets. If an approach is wrong for your product or your budget, we say so and propose a better one.

NDA-friendly and confidential

Confidential by default. We sign NDAs readily, your AWS and Firebase accounts stay yours, and all code and infrastructure are your IP.

Full lifecycle coverage

From idea to development to deployment to support. The team that designs your cloud architecture is the team that runs and maintains it.

How an engagement runs

Discovery
We learn your product, users, constraints, and existing cloud footprint, and agree on what success looks like before any build begins.
Architecture and platform choice
We propose a concrete AWS, Firebase, or combined architecture with the reasoning written down: services, data model, security boundaries, and cost drivers.
Build
Iterative development in short cycles, with infrastructure as code, reviewed pull requests, and working software you can see throughout.
Testing and hardening
Automated tests, security review of IAM roles and Firebase rules, and load checks so the system behaves under real traffic, not just in staging.
Launch
Controlled deployment with monitoring, alerting, and rollback paths in place, plus handover documentation for your team.
Support and iteration
Ongoing maintenance, cost reviews, and feature work after launch, at whatever level of involvement your team needs.
