AI voice agents & receptionists
Phone agents that answer, schedule, take intake and route calls, around the clock.
Best for: clinics, law firms and service businesses buried in calls.

I've spent the last two years putting AI in front of real people: patients calling a clinic, clients calling a law firm, customers proving who they are on camera.
I started on backend APIs and CI/CD, brought that discipline into Video KYC and RAG at Code Himalaya, then built a voice agent answering a US hospital's phones at MeetGabbi. There, a wrong answer isn't a bug report. It's a patient left waiting.
I'm finishing my BSc IT (Hons) in Kathmandu, where my final-year project teaches the city's own traffic signals to adapt. I speak Nepali, English and Hindi.

What people say
For teams and businesses
From a question in your data to an AI system in production: I analyse, model, build and ship, then hand you something you can measure. Pick what you need, or all of it.
Phone agents that answer, schedule, take intake and route calls, around the clock.
Best for: clinics, law firms and service businesses buried in calls.
LangGraph agents that plan, call your APIs and hand off to humans when they should.
Best for: repetitive intake, triage, follow-ups and back-office work.
Chat over your documents, grounded in retrieved sources and tuned to reduce hallucinations.
Best for: support teams, internal wikis and policy-heavy work.
Integrate GPT, Gemini, Groq or open models into your product, with prompts and fine-tuning tuned for accuracy and cost.
Best for: teams adding AI features to an existing product.
Identity verification, liveness checks, OCR and parsing that turns documents into clean data.
Best for: fintech onboarding, KYC and document-heavy operations.
Transcription, summarisation, named-entity recognition and semantic search over text and audio.
Best for: call analytics, meeting notes and search over unstructured text.
Models that predict outcomes from your data, built with scikit-learn, PyTorch or TensorFlow and validated properly.
Best for: teams with historical data and a decision to improve.
Content and similarity-based recommenders using embeddings and vector search, refreshed on a schedule.
Best for: media, e-commerce and content platforms.
Unsupervised models that flag unusual transactions or behaviour in real time.
Best for: fintech, payments and risk teams.
Clean, explore and explain your data, then ship interactive dashboards that decision-makers actually use.
Best for: founders and managers who need answers from their data.
Agents that learn control policies in simulation, with safety guardrails and honest baselines.
Best for: scheduling, control and resource-allocation problems.
Independent evaluation of an AI system against strong baselines, with retrieval quality, hallucinations and real metrics.
Best for: teams unsure whether their model is actually working.
Turn a notebook model into a fast, documented FastAPI service on Docker and AWS.
Best for: teams with a working model and no way to ship it.
Automated pipelines for testing, versioning, deploying and monitoring models.
Best for: teams losing hours to manual releases.
Run large open models on cloud GPUs by managing memory, offloading and streaming inference.
Best for: teams self-hosting speech or language models.
Before you reach out
AI/ML engineering roles focused on voice AI, AI agents and RAG, where the work ships to real users. I'm also open to contract and fixed-scope projects.
Production. My voice agents ran for a US orthopedic hospital, ARC Psychiatry and US law firms. At Code Himalaya I deployed AI services with Docker, AWS and CI/CD.
Yes. At MeetGabbi I worked remotely from Kathmandu with a team in Cincinnati, collaborating with product and engineering on healthcare and legal features.
I've built HIPAA-compliant voice systems with compliance-aware conversation design. My Video KYC system kept face embeddings, audit logs and ID documents securely in Amazon S3.
I measure it against honest baselines. In my traffic project, every trained model had to beat a random-control baseline, not just fixed timers. When it didn't, I said so and worked out why.
