Puttur West · Jaffna · Northern Province
Hashtag Coders builds custom software, websites, and mobile products from 9th Mile Post, Puttur West - for businesses across Sri Lanka and clients abroad who want a Northern Province team with production delivery, not a brochure address.
Commercial searches like “software company Jaffna” or “web and software development Jaffna” usually mean one of three things: lower overhead than Colombo for the same stack, Tamil/English collaboration for Northern Province products, or an offshore partner outside the capital with overlapping hours for Singapore, the UK, Germany, and France. We answer those needs with a fixed office, named engineers, and written scopes.
9th Mile Post, Puttur West, Jaffna 40000, Northern Province - not a Colombo shell company with a remote label.
Sri Lanka Standard Time (UTC+5:30). Strong overlap with Singapore business hours and morning stand-ups for the UK, Germany, and France.
Delivery and client calls in English and Tamil. Localised product copy for Northern Province and island-wide audiences.
Engineers trained around University of Jaffna, SLIIT pathways, and returning diaspora - modern stacks (React, Next.js, Flutter) are normal here, not experimental.

Many buyers searching “custom software development Sri Lanka” also evaluate Jaffna firms for cost and communication. Typical builds from our Puttur office include inventory and POS modules, booking systems, internal ops tools, and customer portals - with clear staging environments and documentation for your staff.
If you only need a marketing site, start with web development. If you need workflows, roles, and integrations, start with custom software development.
Talk through your briefBands are guidance only - always get a written scope. See the website cost guide for quotation checklists.

Practical answers for overseas buyers-timezone overlap, currency, ownership, references, and support-before you reach out. We also serve clients across Singapore, the UK, Germany, and France.
We have shipped for e-commerce retailers, travel operators, news publishers, creative studios, and custom business systems in Sri Lanka and abroad. Live international examples include Brotmann Kriens (Switzerland, brotmann-kriens.com) and Group Transfer Disney (France, grouptransferdisney.com/en)-both with admin panels for day-to-day content control. Local work includes Spices Jaffna (e-commerce), Imagina Creations (studio site), and Ravanaa News (publishing). In discovery we map your industry, integrations, and compliance needs to similar work we have done; if the fit is weak, we say so early rather than force a pitch.
Our office runs Mon–Fri 09:00–18:00 and Sat 09:00–14:00 Sri Lanka Standard Time (UTC+5:30, no daylight saving). Singapore (UTC+8): live calls typically land between about 11:30am and 3:30pm Singapore time during our weekday hours. UK, Germany, and France: morning overlap-roughly 5:30am–12:30pm Central European Time while we are open-suited to stand-ups and decision calls. Outside overlap we use async updates on Slack or email with a same-business-day response target on active projects.
Proposals are issued in LKR for Sri Lanka clients or USD for international engagements. Milestone invoices match the currency in your signed quote. If you need SGD or EUR for internal procurement, we can discuss equivalent quoting-payment terms and bank details are confirmed in the proposal before work starts.
You get a named lead from day one-usually one of our team members. We do not hand you to an anonymous account manager after the sale. Weekly calls, sprint demos, and escalation paths go through that same person.
Timelines are fixed in the written scope and proposal before build work. If we hit a blocker on our side, we flag it early with a revised plan-not silence until the deadline. Client-side delays (content, approvals, third-party API access) are tracked in the shared board and may shift dates without penalty to either party. Material scope additions go through a change request with new dates and cost before we build them. Specific remedies, if any, are only what your signed contract states.
You do. IP for work created under your project transfers to you on final payment-you receive repositories, designs, and agreed deliverables. We do not retain rights to your product codebase or hold it hostage for future work. NDAs and confidentiality are standard before sensitive discussions.
Yes, when there is a sensible match. After an initial fit call we can arrange a short conversation with a client who has agreed to be contacted-often on a similar project type (admin-managed e-commerce, multilingual booking sites, CMS, or internal tools). Public portfolio links such as Brotmann Kriens and Group Transfer Disney are available anytime; private contact details are only shared with permission.
New builds include an agreed warranty window for defects in delivered scope. After that, most clients choose a monthly retainer covering security patches, dependency updates, monitoring, and a small bucket of fix hours-with P1/P2 response times written in when uptime matters. Larger features are quoted as separate change orders, not buried in “free maintenance.” Handover docs and repo access are included so your team or another vendor can take over.

Practical answers for buyers comparing Northern Province vendors and Colombo alternatives.
Yes. We are based at 9th Mile Post, Puttur West, Jaffna 40000, Northern Province (founded 2019). We are not a Colombo-only firm with a marketing address in the North. Discovery calls, stand-ups, and delivery happen with the same team that writes the code.
Custom business software, websites and Next.js apps, mobile apps, cloud hosting and migration, DevOps pipelines, and security hardening. If you need a large enterprise RFP with 50+ seat staff augmentation, we will say so early and point you toward a better fit.
For equivalent scope, Jaffna quotes are often 15–35% lower than Colombo because of payroll and overhead - not because we cut QA. Brochure sites and mid-size custom apps see the clearest gap; senior specialist work converges. Always compare written scopes, not headline package prices.
Yes. We deliver for clients in Sri Lanka and our primary international markets-Singapore, the UK, Germany, and France. Communication is in English; SLST (UTC+5:30) overlaps Singapore hours and morning stand-ups in the UK, Germany, and France.
This page is the commercial overview for buyers searching for a software development company in Jaffna. Use the linked service pages when you already know you need web, mobile, cloud, DevOps, or cybersecurity specifically. Use our Jaffna buyer guides when you are still comparing vendors or budgets.
A short brief helps: goals, users (Sri Lanka vs international), must-have features, integrations (PayHere, Stripe, SMS), content ownership, and a realistic budget band. We reply with a scoped proposal - platform recommendation, timeline, and exclusions - not a one-line package price.
