Conventional software program improvement usually entails weeks of planning, designing, and programming earlier than seeing a working utility. However what if it’s attainable to go from a tough concept to a production-ready system in a matter of minutes?
On this publish, we stroll by way of how we used Kiro, an agentic Built-in Improvement Surroundings (IDE), to construct an entire health middle administration utility that digitizes paper-based health monitoring. We discover Kiro’s spec-driven improvement workflow and see the way it transforms complicated utility improvement right into a streamlined, iterative course of. Our resolution makes use of Amazon DocumentDB because the backend. We present the best way to construct an entire health middle administration system utilizing Kiro synthetic intelligence (AI) and DocumentDB because the backend, which might take customers from preliminary idea to a completely purposeful minimal viable product (MVP) in lower than two hours, as seen in our improvement.
Kiro is an agentic IDE that helps builders go from idea to manufacturing with spec-driven improvement. From easy to complicated duties, Kiro works alongside customers to show prompts into detailed specs—then into working code, docs, and checks.
Why Amazon DocumentDB?
Amazon DocumentDB (with MongoDB compatibility) is a serverless, totally managed native JSON doc database that makes it easy and cost-effective to function vital doc workloads on any scale with out managing infrastructure.
We selected Amazon DocumentDB as our backend database resulting from its schema flexibility and actual time aggregation capabilities. Health knowledge is inherently complicated and varies considerably between purchasers. This complexity stems from the varied nature of health metrics—starting from primary measurements like weight and physique fats share to superior biometrics reminiscent of VO2 max, coronary heart charge variability, and muscle-specific power assessments. Moreover, exercise buildings can fluctuate dramatically, from easy cardio periods to complicated multi-phase power coaching applications with various units, reps, weights, and relaxation durations. Amazon DocumentDB shops exercise applications with nested train buildings, versatile physique measurements that may embrace customized metrics for every consumer, and sophisticated progress monitoring knowledge, all in a pure JSON format.
Amazon DocumentDB aggregation pipeline permits us to effectively slice and cube health knowledge by time durations, train sorts, physique metrics, or customized dimensions, enabling real-time pattern evaluation and complete reporting on consumer progress, efficiency patterns, and objective achievement metrics.

Kiro in motion – constructing a health middle utility
Step 1: Beginning with Kiro specs
We started with a easy dialog with Kiro concerning the health middle administration concept.
Immediate for Kiro
We designated Python as our improvement language and Amazon DocumentDB as our backend database within the immediate. For different elements and frameworks, we delegated these selections to Kiro.
Kiro instantly acknowledged the immediate for spec-driven improvement and started the structured workflow.
Creating the necessities doc
Kiro robotically generates complete necessities in EARS format (Straightforward Strategy to Necessities Syntax). In our instance, it created complete six necessities for our health middle administration system.
Pattern Requirement:
Necessities doc generated by Kiro exhibiting structured consumer tales and acceptance standards
The necessities section helps us perceive precisely what the system ought to do earlier than writing the code. This iterative course of concerned Kiro asking clarifying questions whereas we offered suggestions, persevering with till we developed an entire specification.
Step 2: Architectural design
As soon as necessities had been authorised in Kiro, Kiro moved to the design section. Kiro creates an in depth design doc overlaying:
System structure
Kiro designed a clear MVC structure utilizing Flask:
Database design with DocumentDB
The design makes use of the document-based construction of Amazon DocumentDB to deal with complicated health knowledge relationships. The next are just a few samples from design paperwork.
Consumer Doc – versatile private knowledge
Exercise program – nested train construction
Design paperwork present full design together with excessive stage structure, know-how stack, utility structure, and detailed element interfaces and knowledge fashions.
Excessive stage structure diagram is proven within the following picture:
Knowledge Circulate Diagram is proven within the following picture.
Step 3: Implementation planning
As soon as we approve the design, Kiro strikes to implementation planning. Kiro converts the design into actionable implementation plan. Kiro creates a improvement plan with 15 essential duties with logical sub-tasks, following a test-driven method that builds incrementally. When requesting an MVP model, Kiro simplifies the implementation plan whereas preserving core performance. We additionally handed on the Amazon DocumentDB connection string to make use of as Kiro use test-driven improvement method and construct incrementally. The Amazon DocumentDB connection string factors to a neighborhood host as we already arrange the SSH tunneling as a prerequisite.
Immediate for MVP model
The authentic implementation plan had 15 main duties with 22 sub-tasks. The MVP plan has eight streamlined duties specializing in important options.
For production-ready functions, instruct Kiro to make the most of AWS Secrets and techniques Supervisor for Amazon DocumentDB’s safe credential and implement Amazon Cognito for consumer authentication.
Step 4: Implementation execution
Kiro follows a complete test-driven improvement methodology that helps reliability and high quality at each step of the implementation course of. After finishing every activity or implementation, Kiro robotically runs checks to confirm that the performance has been correctly applied and meets the required necessities. This systematic testing method helps catch points early and maintains code high quality all through the event lifecycle.
As soon as the implementation plan receives approval, Kiro begins executing duties in a sequential method. Every activity is processed one after the other, following a structured method that helps with ensuring correct order and dependencies are maintained. Throughout this course of, Kiro could request your belief in its implementation selections or ask you to confirm particular performance to assist with accuracy.
In our instance, Kiro applied the MVP utilizing by executing the next duties:
- Activity 1: Undertaking construction setup with config
- Activity 2: Amazon DocumentDB connection implementation
- Activity 3: Consumer administration fashions and kinds
- Activity 4: Exercise program administration system
- Activity 5: Physique measurement monitoring with developments
- Duties 6-8: Abstract of dashboard, authentication, and net interface
We strongly suggest verifying the performance each time Kiro requests affirmation. This collaborative method makes certain that every activity is applied accurately earlier than continuing to the following step. By taking the time to validate Kiro’s work when prompted, customers can preserve confidence within the general implementation high quality and catch potential points early within the improvement course of.
Step 5: Operating the online utility
Kiro creates a clear, responsive interface utilizing Bootstrap. Customers can begin an utility regionally utilizing the next command or ask Kiro to run it.

Progress dashboard
The dashboard tracks the consumer’s progress and gives an general abstract.
Utilizing Kiro Hooks for automation
Considered one of Kiro’s highly effective options is Hooks – automated actions triggered by occasions. For our health middle system, we applied a vital infrastructure hook:
Hook: Obtain International Bundle Privateness-Enhanced Mail (PEM)
Function:Â Robotically manages the SSL certificates required for DocumentDB connections
Set off:Â When database-related recordsdata are edited (run.py, database.py, config.py)Â Motion:Â Downloads the Amazon DocumentDB international bundle certificates if lacking
What’s subsequent?
The MVP gives a strong basis for enhancement:
- Cell app integration – Add REST API endpoints
- Superior analytics – Machine studying for progress prediction
