What we build
Full-stack delivery, engineering-led from day one.
Every engagement is scoped and reviewed by someone who has shipped production systems at scale — not handed off to a generic delivery pipeline.
Mobile App Development
Native iOS and Android apps, plus cross-platform builds — architected for offline reliability, battery efficiency and real-world networks.
Mobile app developmentWeb & Cloud Engineering
Web applications and APIs on modern frameworks, backed by AWS-native infrastructure built to scale without a rebuild.
Web developmentEnterprise & ERP Solutions
Custom systems for businesses ready to move beyond spreadsheets — designed around how your team actually works.
Custom software & ERPCloud Hosting & DevOps
Infrastructure setup, CI/CD pipelines, monitoring and ongoing operations — so releases stay boring and reliable.
Software Consultancy
Architecture reviews, technology selection and technical due diligence — an outside engineering view before you commit budget.
AI solutions
Practical AI, engineered for production.
Not demos that stall after the pilot. We build AI features with the same discipline as any production system: measurable accuracy, predictable cost, and your data kept under your control.
Knowledge assistant on your data
A chat assistant that answers from your documents, policies and SOPs — with source citations, role-based access, and "I don't know" when the answer isn't there.
Document intelligence
Extract structured data from invoices, forms, contracts and IDs into your systems — with confidence scores and a human review queue for edge cases.
Customer support agent
An AI agent for your website or WhatsApp that answers questions, looks up orders through your APIs, and hands off to a human with full context.
AI features inside your app
Smart search, summaries, drafting and recommendations added to an existing mobile or web product — without rebuilding it.
Workflow automation agents
Agents that run multi-step back-office work — reports, data entry, CRM updates, reconciliations — with approval steps where a person should decide.
AI readiness & strategy
A short engagement to find the use cases worth building, estimate cost and accuracy, and choose models and hosting that fit your data-privacy needs.
Measured, not guessed. Every AI feature ships with an evaluation set, so accuracy is tracked release to release.
Your data stays yours. Private deployment options on AWS Bedrock or your own cloud; nothing used for model training.
Cost under control. Model choice, caching and limits designed up front, so usage bills are predictable.
Selected work
Real systems, real constraints.

Who's behind the work
Led by an engineer, not an account manager.
Lachhan Software is founded and led with 16+ years of hands-on software engineering experience — including production infrastructure work at Amazon, where the founder owned core modules (Cart, Payment Gateway, Order Summary) during a large-scale platform migration, and helped keep systems stable through peak-traffic events at Amazon's scale.
That same standard carries into every client engagement: architecture decisions grounded in what actually holds up in production, not just what looks good in a proposal deck.

Senior engineering, without the agency overhead.
Engineering-first strategy
No template roadmaps. Every engagement starts with an honest technical assessment of what your product actually needs — not a pre-packaged sprint plan.

Code held to the same standard used to ship systems that support real customers at scale — because that's the standard we were trained in.
Real support, after launch
Two weeks of complimentary live support on every project, with clear, direct access to the person who actually built your system.
