A satellite parts supplier near the El Segundo aerospace corridor once asked us why their support inbox still took four people to manage. Engineers were retyping the same technical specs into emails all day, and nobody had time to fix it. That is usually the moment a company decides it needs a ChatGPT developer instead of another generalist coder, someone who understands prompt design, retrieval pipelines, and where GPT-4 actually breaks down under real usage.
El Segundo's economy leans hard on aerospace, defense contractors, and a growing cluster of media and sports tech firms near the Point Vicente corridor. Each of those industries has oddly specific documentation problems. A defense supplier can't just paste proprietary specs into a public chatbot, so the developer we place has to build retrieval-augmented generation on top of a private vector store, not just call the OpenAI API and hope. That distinction matters more in California, where data handling expectations from enterprise clients tend to be stricter than in smaller markets.
Our developers work in Python and Node.js depending on what your existing stack looks like, wiring LangChain orchestration around GPT-4 so the model only answers from your actual documents instead of guessing. Embeddings get tuned to your domain vocabulary, whether that's flight hardware terminology or licensing contracts, because generic embeddings tend to blur distinctions that matter to your business. We've seen teams skip this step and end up with a bot that sounds confident but answers wrong about a third of the time.
We're an India-based team of about ten engineers, founded in 2015, and we don't have an office in El Segundo or anywhere in California. That's by design. Clients get a developer who overlaps several hours with the Pacific workday, joins your daily standup over Zoom, and hands you full code ownership from day one. It's a different model than hiring locally, and for AI work specifically, we think it's a better one, because the same engineers building RAG pipelines for aerospace clients in California are also solving similar problems for teams in a dozen other countries every week.
Our developers specialize in GPT-4 integration, embeddings, and RAG pipelines, not general web development stretched to cover AI. That focus matters for El Segundo companies with technical documentation to protect.
Even without a California office, our team structures its schedule to overlap with Pacific business hours for standups and reviews.
Founded in 2015, we've shipped over 500 projects for clients in more than 20 countries, including several with the same aerospace and defense compliance concerns common around El Segundo.
Every repository, model configuration, and prompt template belongs to you from the first commit, no exceptions.
You get weekly time logs and sprint notes, so a part-time engagement never quietly turns into a full-time bill.
If GPT-4 and RAG aren't the right fit for your problem, or a simpler rules-based tool would serve California operations better, we'll say so before you sign anything.
One developer embedded in your team full time, suited for companies building a production chatbot or internal RAG tool from scratch.
Good for maintaining an existing GPT-4 integration or handling a defined scope like embeddings tuning.
Best for a short prompt-engineering audit or fixing a specific LangChain pipeline issue without a long commitment.
For larger builds needing a Python backend developer, a Node.js API engineer, and someone focused purely on retrieval quality.
We talk through your use case, whether it's internal search, customer support, or a domain-specific assistant, and flag any early red flags around data sensitivity.
We shortlist one or two developers whose GPT-4 and LangChain background fits your project, and you talk to them directly before deciding.
Your developer reviews existing documentation, data sources, and any prior AI attempts so the first sprint plan isn't built on guesswork.
We scope a two-week block of concrete deliverables, usually starting with the embeddings pipeline or a working RAG prototype.
Your developer joins standups, ships weekly, and adjusts the retrieval or prompt logic as real usage data comes in.
"Ritik and his team at Aneri Developers are top notch! We have been working together for almost 2+ years now and the project continues to evolve exactly how I had envisioned it. His communication is amazing and his attention to detail is even better! The mobile app and back office that we have created has freed up so much of my day to day while also giving my clients much better transparency and service in return too. His pricing is very fair and I feel extremely lucky to have him helping behind the scenes and growing my business! I look forward to all our future endeavors and continued success. Thank you!"
"I used Aneri Developers to build a campaign website. They were responsive, creative and handled any web-site related problems promptly. The turnaround time to implement updates was impeccable. Rutvik was also very patient and gracious. I recommend Aneri Developers for your website development needs."
"Great developer. On Time. Reasonable pricing. I trust working with him. We have an on going business now!"
