Backend Transitioning to AI Dev

Sugam Agrawal — Sat, 17 Jan 2026 06:12:02 +0000

After working with LLMs, I believe the hardest part of the transition for backend engineers isn't the math—it's unlearning determinism.

In traditional distributed systems, Input A always yields Output B. If it doesn't, it’s a bug. With GenAI, Input A might yield Output B today, and a completely different structure tomorrow.

This breaks everything we know about stability at scale. You can't write a standard unit test for a "vibe check." You can't rely on a model to output valid JSON 100% of the time, even with strict prompting. You can't predict latency when the inference provider is overloaded.

The solution isn't better prompt engineering; it's defensive architecture. We need to shift focus from "making the model perfect" to building resilient wrappers—schema validators, circuit breakers, and automated evaluation pipelines that catch regressions before users do.

Treat the LLM like an untrusted, high-latency 3rd-party API, not a magic box.

starting the server:-
*redis-server
running the client:-
*redis-cli

Command:-

    > exists key                                                     //Test if specified key exists.
    > del key1 key2 ... keyN                                         //Remove the specified keys.
    > ttl key                                                        //Returns remaining time to live, in seconds, for a key with EXPIRE set.
    > set key value                                                  //Sets the value of key to the string value.
    > get key                                                        //Gets the value of key
    > rpush key string or
    > lpush key string                                               //Adds the string to the head (rpush) or tail (lpush) of the list at key. 
    > llen key                                                       //Returns the length of the list at key.
    >lrange key start end                                            //Returns the elements of list at key, zero-based. Negative numbers are offset from the end of the list.
    >lset key index value                                            //Sets the element of list key at index to the specified value.
    >lrem key count value                                            //Removes count number of items from the list that have the specified value.
    >lpop key string or
    >rpop key string                                                 //Atomically removes and returns the first (lpop) or last (rpop) element from list key.
    >sadd key member                                                 //Adds member to the set stored at key.
    >srem key member                                                 //Removes member from set key.

    >srandmember key                                                 //Returns random element from set key. spop will remove the element.Return element, or nil object if key is empty or doesn't exist
    >smembers key                                                    //Returns all of the members of set key.
    >HSET KEY field value                                            //Set field and value in HASHMAP
    >HGET key field                                                  //GET Key value from HASHMAP

Planning Projects

Sugam Agrawal — Wed, 22 Sep 2021 08:20:57 +0000

So Here we are to know how to plan your project?
So in industry standard we use a special method to plan the project known as AGILE METHODOLOGY.

What is Agile?
Agile software development refers to a group of software development methodologies based on iterative development,where requirements and solutions evolve through collaboration between self-organizing cross-functional teams.

What is Scrum?
Scrum is a daily team meeting of nearly 15-20 mins where we discuss our problems and work progress with our teammates.

So planning the project includes:-
1. Requirement gathering about the project.
2. Then breaking the projects into small atomic problems.
3. Creating HLD documents which consists of your work to do.
4. Conducting Daily SCRUMS to check upon work progress with teammates.
5. Getting feedback from Customers and using that feedback to update the project.

#For this we can use a software names- JIRA SOFTWARE.
