I'm SM Ashiqurzamman, a senior full-stack developer and AI engineer, and the founder of Ashik Dev. For the last seven years I've helped startups, agencies and product teams ship reliable software: AI agents, voice bots, LLM-powered chatbots, business automation, and full-stack SaaS on React, TanStack, Next.js and Supabase.
On the AI side I build production agents with tools, memory and retrieval not demos. Voice automation for sales and support, chatbots wired to your real data via RAG, and n8n / webhook pipelines that quietly replace hours of manual ops every week.
On the product side my focus is where engineering meets product: design systems, performance, accessibility, type-safe data layers and developer experience. Small, obsessively-considered details add up to interfaces that feel obviously right to the people using them.
I work exclusively through Upwork so every contract is covered by their payment and dispute protection. Whether you need an AI agent, a voice bot, a new SaaS surface, or a senior pair of eyes on an existing codebase, I'd love to hear about it.

How I work
Working principles
The defaults I bring to every engagement — whether it's a weekend audit or a multi-month full-stack build. Worth raising early if your team disagrees with any of them; better to align before contracts are signed than during a sprint.
Type-safe by default
End-to-end TypeScript across UI, server functions, and database schemas. Schemas and inputs validated with Zod so production stays loud-fail, not silent-fail.
Performance and accessibility are features
Lighthouse and axe checks are part of every milestone — not a launch-day scramble. Real Web Vitals on mid-range Android, not just desktop.
Security and RLS from day one
Row-level security policies, least-privilege keys, and audit-friendly migrations on every Postgres/Supabase build. No service keys on the client, ever.
Automate the boring parts
CI, preview deploys, error tracking, and structured logs wired up early so the team isn't reinventing dev infra on a deadline.
Ship in small, demoable slices
Weekly milestones with a recorded demo at the end. Feedback loops stay short and scope changes get priced before they ship.
Design systems, not ad-hoc UI
Shared tokens, primitives, and accessible patterns so the next feature looks consistent without a designer in the loop for every screen.
