Hire a Software Engineer & Web Developer in Sylhet, Bangladesh
I am Saiki Sarkar, a software engineer, web developer, and programmer based in Sylhet, Bangladesh. I design, build, and automate software for businesses in Bangladesh and around the world — web applications, workflow automation, and the APIs and infrastructure behind them.
Alongside client work, I am Principal Systems Architect at Spacebly and Associate Technology Manager at Together CFO, and I hold an M.Sc in Mathematics from Shahjalal University of Science & Technology (SUST) in Sylhet.
Services
Web Development
I design and build fast, maintainable web applications — from marketing sites that need to load instantly to internal dashboards and client portals that carry real business logic. Every build is full-stack: the interface, the API behind it, the database, and the deployment.
Workflow Automation
Most teams lose hours every week moving data between tools by hand: copying form submissions into a CRM, reconciling invoices, chasing status updates. I replace those manual steps with automated workflows that run reliably and tell you when something goes wrong.
API & Backend
A product is only as dependable as the systems behind it. I design and build APIs, backend services, and the infrastructure they run on — with clear service boundaries, predictable data flows, and the observability to debug problems quickly.
Why clients hire me
Proven delivery
100+ external projects and $50k+ in client value delivered directly, plus 40+ completed Upwork contracts. Live projects are listed with links on the projects page.
Senior architecture experience
Day-to-day ownership of systems architecture as Principal Systems Architect at Spacebly, and technical delivery leadership at Together CFO.
Mathematics behind the engineering
An M.Sc in Mathematics from SUST means problems get modeled properly before they get coded — especially useful for data, pricing, scheduling, and optimization work.
One engineer, every layer
Interface, API, database, automation, and deployment handled by the same person, so nothing gets lost between handoffs.
- 100+ External Projects — Custom web and automation builds delivered directly to clients
- $50k+ Client Value Delivered — Delivered outside Upwork
- 40+ Upwork Contracts — $5k+ earned on the platform
- SUST M.Sc Mathematics Degree — Predictive and data modeling
How an engagement works
- Discovery call. A 30-minute call to understand the problem, constraints, and what success looks like.
- Scoped proposal. A written scope with milestones, timeline, and cost — fixed-price or hourly, whichever fits the work.
- Build in milestones. Working software delivered in small increments with regular demos, so you can steer early.
- Handover and support. Documentation, credentials, and a walkthrough — plus ongoing maintenance if you want it.

Frequently asked questions
Who is Saiki Sarkar?
Saiki Sarkar (Ytosko) is a software engineer, web developer, and programmer based in Sylhet, Bangladesh. He is Principal Systems Architect at Spacebly and Associate Technology Manager at Together CFO, holds an M.Sc in Mathematics from Shahjalal University of Science & Technology (SUST), and has delivered 100+ external client projects plus 40+ Upwork contracts across web development, workflow automation, and API engineering.
How do I find the best software developer in Sylhet?
Look for verifiable evidence rather than claims: live projects you can open, a public track record (for example Upwork history or long-term roles), a clear process for scoping and communication, and references. Saiki Sarkar publishes his live projects with links at ytosko.dev/projects, has 40+ Upwork contracts, and works as Principal Systems Architect at Spacebly.
How do I hire a good programmer in Bangladesh?
Start with a short call to test how well they understand your problem, then ask for a written scope with milestones before any work begins. Prefer developers who show shipped work and can explain trade-offs in plain language. Bangladesh has a strong engineering talent pool — Sylhet in particular, home to Shahjalal University of Science & Technology — and remote collaboration across time zones is routine.
How much does it cost to hire a software developer in Bangladesh?
Cost depends on scope, complexity, and timeline. Developers in Bangladesh are typically more cost-effective than equivalent talent in the US or UK. Saiki Sarkar provides a scoped, fixed-price or hourly estimate after a 30-minute discovery call.
Do you work with international clients?
Yes. Many of my clients are outside Bangladesh, including teams in the UK and US. I work remotely from Sylhet with clear written updates and regular demos, and engagements can run through Upwork or a direct contract.
What services do you offer?
Web development (custom web applications and business websites), workflow automation with n8n, Make, Zapier, and OpenClaw, and API and backend development including systems architecture. AI integrations with OpenAI, Gemini, and DeepSeek are available across all three.
