};01/About
I'm a full stack and machine learning engineer with 1 year and 10 months of professional experience, shipping production software from database schema to pixel. I care about clean, maintainable code: small functions, honest names, and tests that document intent. The goal is always a codebase the next engineer can read on day one.
On the backend I design and optimize REST and GraphQL APIs, model data in PostgreSQL and MongoDB, and ship services in Node.js and Go that are containerized with Docker. On the frontend I turn those APIs into fast, accessible interfaces with Next.js, React, and TypeScript.
The machine learning side is where the two halves meet. I train and fine-tune models in PyTorch and scikit-learn, evaluate them honestly, and serve them as versioned APIs that live in the same pipelines and dashboards as the rest of the product. A model that never reaches users is a notebook; I build the ones that ship.
Two disciplines / one engineer
01
Products people use every day.
02
Models that reach production.
02/Stack
Everything here has been used in production, not just in tutorials. Four layers, one system.
Interactive, accessible interfaces that feel instant.
Typed, observable services with clear API contracts.
Schema design, containers, and reliable deployments.
Training, evaluation, and serving models in production.
03/Projects
01SaaS platform2026
Built a multi-tenant SMS gateway for Bangladesh end to end: organization-scoped auth and API keys, a credit wallet whose append-only ledger debits atomically before dispatch and refunds rejected sends, self-service top-ups verified server-to-server through the EPS payment gateway, delivery-report polling, per-recipient link tracking, and an audited admin panel. Exposes a versioned public REST API with idempotent retries and rate limiting.
02Real-time AI platform2026
Built a multi-tenant voice agent platform that answers real phone calls with a speech model I trained myself. A Node gateway streams microphone or SIP call audio to the model over one persistent WebSocket per call, with barge-in, live transcripts, and self-hosted LiveKit WebRTC rooms. Each client gets its own agent with a prompt, HTTP and client-side tools, lifecycle webhooks, a knowledge base, S3 call recordings, and a poisha-precise wallet with per-customer markup. Every turn's speech and text is captured to keep improving the model.
03Machine learning2026
Fine-tuned OmniVoice, a 0.6B speech model on a Qwen3 backbone, for Bengali with LoRA so the Voice AI platform speaks in two consistent voices. Built the full data pipeline from raw call audio: normalized Bengali transcripts so digits match what is spoken, trimmed and loudness-normalized clips to 24 kHz, tokenized them with a neural audio codec, then trained on a free-tier T4 with checkpoints compared by ear against a zero-shot baseline. The chosen adapter is merged into the base model and published to Hugging Face.
04/Experience
From a first production deploy to owning full-stack architecture, shipping ML models into the product, and coordinating delivery across a team.
